Q & A

  • What are the two main types of diabetes mentioned in the script?

    -The two main types of diabetes mentioned are Type 1 and Type 2 diabetes.

  • What is the primary cause of Type 1 diabetes according to the script?

    -Type 1 diabetes is primarily caused by the autoimmune destruction of pancreatic beta cells, which are responsible for producing insulin.

  • What is the typical age range for individuals with Type 1 diabetes?

    -Type 1 diabetes is usually seen in younger individuals, typically those under the age of 30.

  • How does insulin resistance in Type 2 diabetes affect the body's ability to regulate glucose?

    -In Type 2 diabetes, insulin resistance leads to the body's inability to effectively use insulin, resulting in high blood glucose levels as cells do not take up glucose efficiently.

  • What is the role of adipokines in the development of Type 2 diabetes?

    -Adipokines, released by fatty tissue in obese individuals, cause alterations in metabolic parameters that can lead to insulin resistance and the development of Type 2 diabetes.

  • What are the common autoimmune diseases associated with Type 1 diabetes?

    -Autoimmune diseases such as celiac disease and Hashimoto thyroiditis have been linked and are commonly associated with Type 1 diabetes.

  • What is the term used to describe the condition where the body cannot effectively use glucose due to insulin deficiency?

    -The condition is referred to as hypoglycemia, which is characterized by high blood glucose levels because glucose is not being taken up into the cells.

  • What are the classic symptoms of hyperglycemia known as?

    -The classic symptoms of hyperglycemia are known as the 3Ps: polyurea (frequent urination), polydipsia (increased thirst), and polyphagia (increased hunger).

  • What is Diabetic Keto Acidosis (DKA) and what type of diabetes is it more commonly associated with?

    -Diabetic Keto Acidosis (DKA) is a condition where the body, lacking insulin, starts breaking down fats for energy, leading to the production of ketone bodies that can cause metabolic acidosis. It is more commonly associated with Type 1 diabetes.

  • What is the difference between DKA and Hyperglycemic Hyperosmolar Syndrome (HHS) in terms of ketone body production?

    -In DKA, ketone body production is present due to the lack of insulin, whereas in HHS, ketone body production is not a feature as the body still produces some insulin, preventing the shift to ketone body formation.

  • What are the chronic complications of diabetes that can affect the cardiovascular system?

    -Chronic complications of diabetes that affect the cardiovascular system include macrovascular complications such as stroke, TIA (transient ischemic attack), coronary artery disease, myocardial infarction, and peripheral artery disease.

  • How does hyperglycemia contribute to the development of atherosclerosis?

    -Hyperglycemia can trigger non-enzymatic glycation, which accelerates atherosclerosis by causing damage to blood vessels, leading to thickening of the basement membrane and increasing the risk of plaque formation.

  • What are the common treatments for Type 1 diabetes?

    -Treatments for Type 1 diabetes include the administration of insulin, which can be rapid-acting, short-acting, intermediate-acting, or long-acting, depending on the patient's needs.

  • What is the typical first-line medication for treating Type 2 diabetes?

    -Metformin is typically the first-line medication used to treat Type 2 diabetes.

  • What are the common treatments for diabetic ketoacidosis (DKA)?

    -Treatments for DKA include fluid replacement, electrolyte correction (especially potassium), insulin therapy to reduce ketone production, and monitoring and managing acid-base balance.

  • How is the management of hyperglycemic hyperosmolar syndrome (HHS) different from DKA?

    -HHS management focuses on fluid and electrolyte replacement, insulin therapy to address hyperglycemia, and careful monitoring of osmolarity to prevent rapid shifts that could worsen the condition, unlike DKA, which emphasizes ketone body reduction.

🔬 Introduction to Diabetes Mellitus

The video begins with an introduction to diabetes mellitus, focusing on the pathophysiology of type 1 and type 2 diabetes. Type 1 diabetes is typically seen in younger individuals and is characterized by the destruction of pancreatic beta cells, leading to insulin deficiency. This deficiency results in reduced insulin receptor activation, hindering glucose uptake by cells and causing hyperglycemia. The destruction of beta cells is often due to an autoimmune attack, associated with conditions like celiac disease and Hashimoto's thyroiditis. Type 2 diabetes, more common in older individuals, is linked to metabolic syndrome and involves insulin resistance, where cells do not respond effectively to insulin, leading to high blood glucose levels. The lecture emphasizes the importance of understanding these differences for effective management.

05:00

💉 Complications of Diabetes and Pathophysiology

This paragraph delves into the complications associated with diabetes, particularly the metabolic changes that occur due to high glucose levels. It discusses how beta cells, when overworked, release amyloid proteins that can lead to fibrosis and destruction of these cells, eventually causing insulin deficiency. The video also covers the classic symptoms of diabetes, such as polyuria, polydipsia, and polyphagia, which result from hyperglycemia. The osmotic effects of glucose in the bloodstream lead to increased thirst and urination, and the breakdown of alternative energy sources like proteins and fats can cause weight loss and increased hunger. The paragraph concludes with a discussion on the acute complications of diabetes, such as diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar syndrome (HHS), which can arise from stress responses and the release of hormones like cortisol and catecholamines.

10:01

🌡 Differentiating DKA and HHS in Diabetes

The video script clarifies the differences between diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar syndrome (HHS). DKA is more common in type 1 diabetics and is characterized by the absence of insulin, leading the body to break down fats for energy, resulting in ketone body production and metabolic acidosis. Symptoms include fruity breath, rapid breathing, and high glucose levels. In contrast, HHS is more prevalent in type 2 diabetics and involves insulin resistance rather than insulin deficiency. This condition is marked by high blood glucose without ketosis, leading to severe dehydration and potential mental status changes due to hyperosmolarity. The paragraph emphasizes the importance of recognizing these conditions and their distinct management approaches.

15:03

🏥 Managing Acute Complications of Diabetes

This section of the video script discusses the treatment of acute complications in diabetes, specifically focusing on DKA and HHS. The primary goal in managing these conditions is to address severe dehydration through fluid replacement, typically with half normal saline or LR solution. For DKA, insulin therapy is crucial, starting with an insulin infusion and monitoring the anion gap to adjust the infusion rate. Potassium levels must be normalized before initiating insulin therapy to prevent hypokalemia. In cases of severe acidosis, bicarbonate may be administered. For HHS, the focus is on treating hyperglycemia and hyperosmolarity with insulin infusions, closely monitoring glucose levels and osmolarity, and ensuring potassium supplementation to counteract the effects of insulin-induced shifts in potassium.

20:05

🛠 Chronic Complications and Management of Diabetes

The video script highlights the importance of managing chronic complications of diabetes, such as retinopathy, nephropathy, neuropathy, and atherosclerosis. Annual eye exams are recommended to detect and prevent retinopathy, with treatments like VEGF inhibitors and laser photocoagulation considered if necessary. Nephropathy is managed through annual urine albumin and creatinine ratio tests, with ACE inhibitors or ARBs used to reduce albuminuria and slow CKD progression. Neuropathy management involves annual foot exams and treatments for neuropathic pain, such as gabapentin or duloxetine. Atherosclerosis prevention includes annual lipid panel checks and the use of statins and aspirin for patients at high risk of cardiovascular disease. The script emphasizes the need for proactive management to reduce the long-term impact of diabetes.

25:06

💊 Treatment Approaches for Type 1 and Type 2 Diabetes

The video script outlines the treatment strategies for type 1 and type 2 diabetes. For type 1, insulin therapy is essential, with different types of insulin like rapid-acting, short-acting, intermediate-acting, and long-acting used based on meal times and basal needs. A basal-bolus regimen is commonly used, involving long-acting insulin for baseline coverage and rapid-acting insulin for mealtime control. Type 2 diabetes treatment starts with lifestyle changes and metformin, with additional anti-diabetic medications added if A1C goals are not met. These may include GLP-1 agonists, SGLT2 inhibitors, DPP-4 inhibitors, and insulin, depending on the patient's specific needs and risk factors. The script emphasizes the importance of individualized treatment plans based on patient history and metabolic parameters.

30:07

📈 Monitoring and Adjusting Diabetes Treatment

This paragraph discusses the importance of monitoring and adjusting diabetes treatment plans based on A1C levels and other clinical factors. For type 2 diabetes, if A1C remains above target after three months on metformin, additional anti-diabetic medications are considered. The choice of second and third line agents depends on the patient's underlying conditions, such as coronary artery disease, CKD, or weight loss goals. Insulin therapy may be initiated if A1C remains above 9.5% despite multiple anti-diabetic medications. The script underscores the need for regular A1C testing and medication adjustments to achieve optimal glycemic control and reduce the risk of complications.

35:08

🏥 Hospital Management of DKA and HHS

The final paragraph of the video script focuses on the in-hospital management of DKA and HHS. It emphasizes the need for aggressive fluid replacement, potassium monitoring, and insulin therapy. For DKA, regular insulin infusion is used to reduce ketosis, with the rate adjusted based on the anion gap. If the patient becomes hypoglycemic, dextrose is added to the IV fluids to maintain blood glucose levels. For HHS, the primary focus is on treating hyperglycemia and hyperosmolarity, with insulin infusions adjusted based on hourly glucose levels. Potassium supplementation is crucial to prevent hypokalemia, and the script concludes with a reminder of the importance of comprehensive care in managing these acute diabetic complications.

40:09

🌟 Conclusion and Final Thoughts on Diabetes Management

The video concludes with a summary of key points and a reminder of the importance of comprehensive diabetes management. It emphasizes the need for regular monitoring, appropriate medication adjustments, and proactive management of both acute and chronic complications. The script encourages viewers to apply the knowledge gained in the lecture to improve patient outcomes and manage diabetes effectively. The presenter expresses hope that the information was clear and helpful, and signs off with a reminder to stay informed and engaged in diabetes care.

Keywords

💡Diabetes Mellitus

Diabetes Mellitus is a chronic metabolic disorder characterized by high blood sugar levels. In the video, it is the central theme, with a detailed discussion on its two main types, pathophysiology, and treatment approaches. The script mentions the distinction between Type 1 and Type 2 diabetes, emphasizing their different causes and management strategies.

💡Insulin

Insulin is a hormone produced by the pancreas that regulates blood sugar levels by allowing glucose uptake into cells. The script explains that in Type 1 diabetes, there is an insulin deficiency due to the destruction of insulin-producing beta cells, while in Type 2 diabetes, there is insulin resistance where cells do not respond effectively to insulin.

💡Autoimmune Attack

An autoimmune attack refers to the body's immune system mistakenly targeting and damaging its own tissues. In the context of Type 1 diabetes, the script describes how an autoimmune attack destroys pancreatic beta cells, leading to insulin deficiency.

💡Metabolic Syndrome

Metabolic Syndrome is a cluster of conditions that increase the risk of heart disease and type 2 diabetes. The script associates Type 2 diabetes with metabolic syndrome, highlighting factors such as obesity, high blood pressure, and abnormal cholesterol levels that contribute to insulin resistance.

💡Hyperglycemia

Hyperglycemia is a condition where there is a high concentration of glucose in the blood. The script discusses hyperglycemia as a downstream consequence of insulin deficiency or resistance, leading to glucose accumulation in the bloodstream and the associated clinical manifestations.

💡Polyuria, Polydipsia, Polyphagia

These terms describe the classic symptoms of diabetes: excessive urination (polyuria), excessive thirst (polydipsia), and increased hunger (polyphagia). The script explains how these symptoms arise due to the body's attempt to manage high blood sugar levels.

💡Diabetic Ketoacidosis (DKA)

Diabetic Ketoacidosis is a metabolic complication that occurs in diabetes, characterized by high levels of ketones in the blood. The script describes DKA as a potentially life-threatening condition more common in Type 1 diabetes, where the lack of insulin leads to the breakdown of fats for energy, resulting in acidic blood.

💡Hyperosmolar Hyperglycemic Syndrome (HHS)

Hyperosmolar Hyperglycemic Syndrome is a condition where there is severe dehydration and very high blood sugar levels without ketosis. The script differentiates HHS from DKA, noting its association with Type 2 diabetes and the absence of ketone body formation.

💡A1C

A1C, or glycated hemoglobin, is a measure of average blood sugar levels over the past 2-3 months. The script mentions A1C as a critical test for diagnosing diabetes and monitoring its control, with a value greater than 6.5% indicating diabetes.

💡C-Peptide

C-Peptide is a biomarker used to assess insulin production by the pancreas. The script refers to C-Peptide levels to differentiate between Type 1 and Type 2 diabetes, with lower levels typically indicating Type 1 diabetes due to the destruction of beta cells.

💡Neuropathy

Neuropathy is a type of nerve damage that can occur in people with diabetes, leading to pain, numbness, or tingling in the hands and feet. The script discusses diabetic neuropathy as a complication that can affect the quality of life and requires careful management.

H what's up Ninja nerds in this video

play00:12

today we're going to be talking about

play00:13

diabetes metis this is a monster lecture

play00:16

let's get right into it when we talk

play00:18

about the pathophysiology of diabetes

play00:20

meitus there is two there's type one and

play00:22

type two and the pathophysiology does

play00:24

differ somewhat so for type one the

play00:27

concept behind this is that it's usually

play00:28

in a younger individual usually want to

play00:30

think age less than 30 that's not always

play00:32

the case but it is most commonly going

play00:34

to be like this for your board exams the

play00:37

other important thing to remember for

play00:38

this is that the pathophysiology is

play00:40

different in the sense that the beta

play00:41

cells the pancreatic beta cells that are

play00:43

ones that are responsible for producing

play00:45

insulin are being destroyed and because

play00:48

of that they're not going to be able to

play00:49

produce an adequate amount of insulin so

play00:51

there'll be a reduction or deficiency of

play00:53

insulin in these patients now with a

play00:56

reduction in insulin what leads to the

play00:58

downstream consequence here is that

play01:00

insulin won't be able to bind on to its

play01:02

appropriate receptors right so these

play01:04

insulin receptors aren't going to be

play01:05

activated as much what do these do

play01:07

they're supposed to come down and tell

play01:09

this glucose transporter to allow for

play01:12

glucose to be brought easily into the

play01:14

cell and to be metabolized and undergo

play01:16

oxidation processes or glycogenesis Etc

play01:20

however since insulin isn't sending the

play01:22

signal appropriately glucose will not be

play01:23

taken up into the cell and instead it

play01:25

will remain in the bloodstream it'll

play01:27

develop something called

play01:28

hypoglycemia this is really the big

play01:31

pathophysiological difference now the

play01:33

question comes is what's leading to the

play01:35

destruction of the beta cells correct

play01:36

and it's usually an autoimmune attack of

play01:39

the beta cells so there has been some

play01:41

Associated like autoimmune diseases like

play01:43

celiac disease maybe Hashimoto

play01:45

thyroiditis that have been linked and

play01:47

very commonly associated with type 1

play01:49

diabetes the reason why is there's these

play01:52

certain types of like gene mutations in

play01:53

the HL drr3 and hr4 that may make the

play01:57

immune system a little bit more

play01:58

hyperactive than it should be

play02:00

what do I mean well let's say that a

play02:02

patient has these immune system cells

play02:04

they become exposed to an environmental

play02:05

agent of some particular etiology and

play02:08

what happens is this causes these immune

play02:10

system cells to inadvertently become

play02:12

hyperactive and produce lots of cyto

play02:14

kindes that then stimulate plasma cells

play02:17

these plasma cells become stimulated in

play02:19

such a way that they start to make

play02:21

antibodies

play02:23

inappropriately and these antibodies

play02:24

that are produced they're going to start

play02:27

attacking proteins that unfortunately

play02:29

look like those environmental agents and

play02:32

these proteins that they're going to

play02:33

attack is going against be against the

play02:35

beta cells the cells that are producing

play02:37

insulin so you'll produce these

play02:39

antibodies like the anti-gad antibodies

play02:41

which is a very critical enzyme within

play02:43

the beta cells that helps with the

play02:44

production of insulin and these ones

play02:47

that actually go against the eyet cells

play02:49

again the eyelet cells of langerhan the

play02:51

cells of the pancreas that are again

play02:53

responsible for producing hormones such

play02:55

as the beta cells and the alpha cells so

play02:57

again you're going to be destroying

play02:58

those cells leading to the reduction in

play03:03

insulin in comparison type 2 diabetes

play03:06

malius you want to think about this in a

play03:08

patient who is a little bit older

play03:10

usually the age is greater than 40 but

play03:12

it can happen in younger individuals

play03:13

especially in the more modern era what

play03:16

you really want to associate this with

play03:18

is more particularly uh metabolic

play03:20

syndrome so in patients who are obese

play03:22

they may have kind of a transition into

play03:25

this adipokine process where their fatty

play03:27

tissue is releasing adipokines and

play03:29

causing a lot of alterations within some

play03:32

other metabolic parameters for example I

play03:34

may drop down my HDL I may increase my

play03:37

triglycerides to greater than 150 my BP

play03:40

might start trending up to greater than

play03:42

130 over 85 my blood glucose may start

play03:45

kind of going up to greater than 100 my

play03:47

waist circumference may start exceeding

play03:49

40 if I'm a male uh 35 of I'm a female

play03:52

and if I have at least three out of five

play03:54

of these I have what's called metabolic

play03:55

syndrome so usually in patients who are

play03:58

a little bit older and have features of

play03:59

metabolic syndrome what we found is that

play04:01

these things alter the insulin receptors

play04:04

in other words it makes the insulin

play04:06

receptors less sensitive and more

play04:07

resistant to

play04:08

insulin so what the heck does that mean

play04:12

that means if these receptors are not

play04:14

responding to insulin then they're not

play04:16

going to be as good at being able to

play04:18

stimulate this receptor that's supposed

play04:20

to take glucose up into the cell and as

play04:23

a result glucose will build up in the

play04:25

bloodstream this is referred to as

play04:27

hypoglycemia this high glucose will then

play04:30

tell the pancreatic beta cells hey dude

play04:32

glucose is pretty high here you want to

play04:34

do something about it and the beta cells

play04:36

will say okay I got you I'm going to

play04:38

release a lot of insulin and other types

play04:39

of molecules this insulin that's being

play04:42

released though you have to remember

play04:44

it's not going to work properly on these

play04:46

tissue cells because again these

play04:48

receptors are less sensitive why likely

play04:50

because of metabolic syndrome these

play04:52

particular factors that we just talked

play04:54

about above so because of that again

play04:56

they're not going to take the glucose up

play04:58

into the cells it's going to build up

play04:59

and they start going to developing

play05:00

really bad high glucose

play05:02

levels the other thing that's really

play05:04

important to remember here in these

play05:05

patients is that whenever the beta cells

play05:07

are pumping out tons of insulin the

play05:09

other complication that we see here is

play05:11

that there's other proteins that are

play05:12

released called ameloid proteins ameloid

play05:14

proteins whenever you're releasing tons

play05:16

and tons of insulin you're releasing

play05:17

tons and tons of amalo proteins and

play05:20

these over time can lead to fibrosis and

play05:22

destruction of the actual beta cells to

play05:25

the point where the beta cells die and

play05:27

they aren't able to produce enough

play05:29

insulin and so that's the difference

play05:32

over time is that initially in a patient

play05:33

who has Type 2 diabetes they'll have

play05:35

insulin resistance hypoglycemia and high

play05:37

insulin levels but over time with more

play05:41

amalo deposition their insulin levels

play05:43

will drop and they'll kind of start

play05:44

taking on the characteristics of a type

play05:46

1

play05:47

diabetic so metabolic syndrome is going

play05:49

to be one of the big features here but

play05:51

there's also been a lot of studies that

play05:53

have shown that family history can be

play05:55

you know accompanied to this so there

play05:57

may be some type of genetic relationship

play05:59

here that causes an alteration in the

play06:01

sensitivity of the insulin receptors not

play06:03

just these factors

play06:05

themselves we know now that hypoglycemia

play06:08

is the common thread between type 1 and

play06:10

type two diabetes though right now often

play06:14

times this will lead to the classic 3p

play06:16

presentation polyurea polyphasia

play06:19

polydipsia how well hyperglycemia

play06:22

whenever this happens it actually is one

play06:24

of the solutes of our bloodstream so the

play06:26

it's going to lead to a change in What's

play06:28

called the osmolarity of the blood with

play06:31

higher amounts of glucose comes a higher

play06:33

osmolarity it's a part of our normal

play06:35

osmolarity calculation so whenever our

play06:38

osmolarity goes up there's a couple

play06:40

things that happen one is it starts to

play06:44

activate the osmo receptors in the

play06:46

hypothalamus right the subicular organ

play06:49

the lamina terminalis and what happens

play06:51

is when they become stimulated they

play06:52

start causing an increase in our thirst

play06:55

so now we're going to start getting

play06:56

thirsty trying to drink tons and tons of

play06:58

water why the concept is that if we

play07:00

drink more water will then help to

play07:02

dilute down the amount of solutes in our

play07:04

bloodstream and reduce the osmolarity

play07:06

all right but you're still going to have

play07:07

hypoglycemia that will

play07:09

persist the other concept is when

play07:11

patients have hypoglycemia that Sugar

play07:13

that's not getting taken into the cells

play07:14

will get filtered across the Glarus into

play07:17

the kidney tubules and what glucose is

play07:20

it's an osmotic molecule and it'll draw

play07:22

with it a ton of water and these

play07:25

patients can have massive what's called

play07:27

osmotic diuresis and pee out very large

play07:29

volumes of urine or they have to pee

play07:31

more frequently and this is called

play07:33

polyura problem with this is that now

play07:36

not only is your sugar going up which is

play07:38

causing an increase in your

play07:39

hyperosmolarity but you're also getting

play07:41

rid of a ton of water and if I pee out a

play07:43

ton of water the amount of water I have

play07:45

in my bloodstream starts going down

play07:46

because I'm becoming dehydrated so now I

play07:48

have high glucose and low water that's

play07:51

going to make even more hyperosmolar and

play07:53

make me even more thirsty so it's a very

play07:55

vicious cycle the polyphasia one's very

play07:58

interesting and these patients they're

play08:00

not utilizing the main source of kind of

play08:03

fuel which is the

play08:05

carbohydrates so because of that they

play08:06

start taing into alternative sources

play08:09

they start breaking down proteins in

play08:11

particular tissues and they start

play08:12

breaking down fats in other tissues

play08:14

because they need that to generate ATP

play08:16

so as I break down proteins and I break

play08:18

down lipids I start chewing through this

play08:20

metabolic kind of fuels and this could

play08:23

lead to a catabolic state that leads to

play08:25

increased hunger because as I start kind

play08:27

of breaking down all these molecules

play08:30

right I'm going to increase my

play08:32

metabolism increase my heat generation

play08:34

and this will start causing the people

play08:35

to be in much more hungry right so this

play08:38

is another thing to also consider and

play08:39

usually in type 1 diabetics this

play08:41

hypercatabolic state can be so insane

play08:43

that they actually could be uh have

play08:45

weight loss so they actually can lose

play08:47

weight in type

play08:48

ones all right that's a lot of stuff to

play08:51

talk about with diabetes with the path

play08:53

of fiz but I think it really sets us up

play08:55

for the next part here which is what are

play08:57

some of the complications and the scary

play08:59

issues that can arise in patients with

play09:00

diabetes metis where they live with this

play09:02

very chronically high high glucose or in

play09:05

the scary scenarios they have very acute

play09:08

rise of glucose so there's something

play09:10

that you really need to remember and

play09:12

this is called dka and HHS this is a

play09:14

part of our hyperglycemic crisis and a

play09:17

patient who has diabetes and they

play09:19

experience an infection maybe they have

play09:20

a myocardial infarction they have

play09:23

pancreatitis or they have some type of

play09:25

like surgical procedure of some sort

play09:27

what happens is that in the States you

play09:30

create a stress response that stress

play09:33

response will then increase the release

play09:35

of your catacol amines like

play09:36

norepinephrine and epinephrine via the

play09:38

sympathetic nervous system and it'll

play09:40

also increase the release of cortisol

play09:43

both of these guys are Bad News Bears

play09:46

especially in a patient with diabetes

play09:47

you want to know why because they're

play09:49

going to increase

play09:50

glycogenolysis

play09:52

gluconeogenesis and they are going to

play09:54

lead to a very high glucose level and

play09:57

when you have a high glucose level and a

play09:58

patient already has diabetes you have a

play10:00

recipe for some disaster such as dka and

play10:04

HHS diabetic keto acidosis and

play10:06

hypoglycemic hyperosmolar syndrome now

play10:09

we have to differentiate between these

play10:11

two so let's talk about that so first

play10:13

one's dka I like to remember more

play10:16

particularly that dka is going to be

play10:17

something that's more likely to be seen

play10:19

in type 1 diabetics it can be seen in

play10:21

type two diabetics but it's much more

play10:23

common in type ones the concept behind

play10:26

diabetic keto acidosis is that the

play10:28

pancreatic beta cells are not making

play10:29

insulin if you're not making insulin the

play10:32

concept behind this is that you're not

play10:33

going to be taking glucose up into the

play10:35

cells if you don't take glucose up into

play10:37

the cells your body has to start tapping

play10:39

into alternative source to generate ATP

play10:43

and that's usually starts chewing

play10:44

through fats and it does this through a

play10:47

process called

play10:48

ketogenesis so what happens is you start

play10:51

breaking down lipids in your adapost

play10:53

tissue and in your liver what happens is

play10:55

those fatty acids get taken up into your

play10:57

liver and it starts chewing through them

play10:59

via a process called beta

play11:02

oxidation unfortunately when you take

play11:04

fatty acids and convert it into aeta you

play11:07

may be doing way too many of them that

play11:08

acetyl Co gets kind of built up and it

play11:10

can't go into the kreb cycle so what

play11:13

happens is it shunts into an alternative

play11:15

cycle which is making Ketone bodies like

play11:16

beta hydroxy uate and

play11:19

acetoacetate these Ketone bodies are

play11:21

problematic the reason why is is that

play11:23

they can kind of cause especially the

play11:25

acetone which is one of the products of

play11:27

the Ketone bodies they can cause the

play11:29

breath to be very

play11:30

fruity the other thing is that they can

play11:33

actually release protons and when it

play11:35

releases protons it drops the pH of the

play11:38

blood and it can actually cause

play11:39

metabolic acidosis and these are kind of

play11:42

organic acids so they have the

play11:43

capability of causing an Anin Gap

play11:45

metabolic acidosis where the anine Gap

play11:47

is greater than 12 and the pH is very

play11:49

low less than

play11:51

7.35 the other thing is because they're

play11:53

super acidotic this actually stimulates

play11:55

the peripheral chemo receptors and tells

play11:58

the patient to breathe faster to

play12:00

hopefully breathe off more CO2 and then

play12:03

by doing that hopefully you'll bring up

play12:04

the pH so often times as a result these

play12:07

patients are breathing very fast and we

play12:09

call this cous small breathing very deep

play12:11

and fast

play12:13

breathing going back to the problem with

play12:15

having less insulin is that you don't

play12:16

take glucose up into the cells and so

play12:18

their glucose goes up as well and this

play12:20

glucose can be pretty high sometimes

play12:21

greater than like 250 uh in a patient

play12:24

with dka so if I have type 1 diabetes I

play12:27

have keto acidosis and H hyper glycemia

play12:30

that really kind of gives me the the

play12:31

recipe for a patient having

play12:33

dka other things that are really

play12:35

important to remember with these

play12:36

patients with dka that are complications

play12:38

is when you have very very high glucose

play12:40

it actually has the capability of kind

play12:42

of pulling potassium out of the cells

play12:44

and so you can get a really total body

play12:45

potassium depletion another thing is

play12:47

that it's going to cause osmotic

play12:48

diuresis when you have lots of glucose

play12:50

into the bloodstream it gets filtered

play12:51

into the kidneys it's going to pull a

play12:52

ton of water with it and these patients

play12:54

can develop massive polyurea and

play12:57

dehydration now with that being said we

play13:00

go to HHS HHS is hyperglycemic

play13:03

hyperosmolar syndrome I want you to

play13:05

think type 2 diabetics now remember I

play13:07

told you that dka it is more common in

play13:09

type one you can see it in type two but

play13:11

it's usually at the end stage when the

play13:13

insulin levels pretty much dropped and

play13:16

HHS I'm thinking early type 2 diabetics

play13:19

now in this particular scenario you

play13:20

pancreatic beta cells are still

play13:22

producing insulin it's just not a

play13:23

sufficient amount right but you're still

play13:26

producing to some some of this to some

play13:27

degree

play13:29

problem is is that it is enough insulin

play13:32

for your body to use some of the glucose

play13:35

but it's not it's not the problem enough

play13:37

where you'll actually start kind of

play13:38

tapping in to the Ketone body formation

play13:41

so that's the big difference they'll

play13:43

have enough insulin that they don't have

play13:45

to tap into the liver and start

play13:47

generating Ketone bodies that's one huge

play13:49

difference between HHS and dka is that

play13:53

there is no ketogenesis so there's not

play13:54

going to be any cous small breathing

play13:56

there's not going to be an anap

play13:57

metabolic acidosis there's not going to

play13:58

be any Fruity breath but you are going

play14:00

to have all the other complications such

play14:02

as insulin resistance where they're not

play14:04

going to respond to the insulin they're

play14:06

not going to take the glucose simp into

play14:07

the cell it builds up in the bloodstream

play14:10

you pull potassium out of the cells and

play14:11

depletes your total body potassium you

play14:13

cause a lot of water to be lost into the

play14:15

urine and cause polyera and dehydration

play14:17

the last thing that's really interesting

play14:19

here in these patients is that their

play14:21

glucose can be so high greater than 600

play14:24

milligram sometimes to the point where

play14:26

it can cause the osmolality of the blood

play14:28

to start PR exceeding

play14:30

320 and the problem with this is this

play14:33

starts causing

play14:36

encylopaedia

play14:38

altered with respect to their mental

play14:40

status and that's a really big

play14:42

difference here so you're not going to

play14:44

see this kind of effect as clear as you

play14:46

would see dka and you're not going to

play14:48

see keto acidosis and HHS as well to

play14:52

really kind of recap this I think the

play14:54

big thing to remember here is in between

play14:55

these two is type one type two again

play14:58

when we're think thinking about DK it's

play15:00

more likely type one HHS more likely

play15:02

type two which one's gonna have more

play15:05

significant hypoglycemia HHS can get up

play15:08

into the 600s or greater dka can get up

play15:10

above greater than

play15:12

250 dehydration HHS is going to be

play15:15

profound hypoglycemia that's going to

play15:16

cause significant osmotic diuresis

play15:19

polyura and profound dehydration DK they

play15:21

will be dehydrated but not as

play15:23

significantly keto acidosis you're going

play15:25

to see that in dka because they don't

play15:27

have any insulin h s you get a little

play15:29

bit of insulin enough that you don't

play15:30

have to tap into the Ketone bodies

play15:32

hyperosmolarity you're going to see a

play15:34

very high hyperosmolarity almost G than

play15:36

320 for patients who have HHS not as

play15:39

severe in patients with

play15:41

dka the other thing is dka is usually

play15:43

rapid so these patients they develop

play15:46

severe hypoglycemia keto acidosis

play15:49

dehydration Etc whereas HHS is more of a

play15:52

gradual slow Insidious

play15:54

onset all right that covers the

play15:56

hyperglycemic crisis which is one of the

play15:58

most Terri terrifying complications of

play16:00

diabetes what about the more chronic

play16:02

like masro macrovascular complications

play16:04

that you can experience if a patient has

play16:06

chronic hyperglycemia so one of the big

play16:08

things to remember is if again your

play16:09

patient has like no insulin or they're

play16:11

having insulin resistance whatever this

play16:13

you know the issue is they're not taking

play16:14

glucose into the cell so they're living

play16:15

with hypoglycemia one of the problems

play16:17

with hypoglycemia is that it can

play16:19

actually trigger something called

play16:20

non-enzymatic glycation in other words

play16:22

you can take proteins and lipids and

play16:23

bind glucose onto them problem with this

play16:26

is is that this really accelerates

play16:27

atherosclerosis

play16:29

whether it be Highline or basement

play16:30

membrane thickening you're really

play16:32

causing damage to the blood vessels the

play16:34

blood vessels become more thick and they

play16:36

become more high risk for

play16:38

atherosclerosis the problem with having

play16:40

atherosclerosis is now that this patient

play16:42

can have plaqued up vessels that supply

play16:44

their brain they end up with a Tia or a

play16:45

stroke they can end up with potentially

play16:47

coronary artery disease from pla up

play16:49

myocardial from pla up coronary arteries

play16:52

in severe cases they even have very high

play16:54

risk of myocardial infarction and on top

play16:57

of that they also can pla up some of the

play16:58

vessels that supply their lower

play16:59

extremities and end up with peripheral

play17:01

artery disease in the form of

play17:02

claudication or sometimes severe ulcers

play17:05

that can even become infected and even

play17:08

chronic

play17:09

lisia these are what we call

play17:11

macrovascular complications so big

play17:14

things like Strokes Tia again myocardial

play17:17

infarction CAD pad critical osmia

play17:21

there's other vessels that can become

play17:22

atherosclerotic and they can cause

play17:24

injury but particularly more at the

play17:26

smaller microscopic level this this is

play17:28

going to be something that we call

play17:29

diabetic nephropathy and retinopathy so

play17:33

when patients have diabetic nephropathy

play17:34

you actually cause damage to the

play17:37

particularly to the Glarus and a lot of

play17:39

injury to the Glarus Glarus sclerosis

play17:41

starts to occur and as a result these

play17:43

patients have difficulty being able to

play17:45

excrete waste products um and also they

play17:48

lead to a lot of loss of albumin due to

play17:50

damage to their nephrons so you'll see

play17:52

these patients will have significant

play17:53

increased risk of developing chronic

play17:55

kidney disease and we'll see that based

play17:57

on an increase in their GFR

play17:58

as well as a very significant loss of

play18:00

albumin in their urine retinopathy is

play18:03

another one they can really cause a lot

play18:05

of damage to the blood vessels and

play18:07

plaque these puppies up so these

play18:09

patients can start off with maybe like

play18:10

Little

play18:11

microaneurysms they can cause hard

play18:13

exudates which are these kind of like

play18:14

little lesions that kind of occur

play18:16

outside of the vessels and the the

play18:18

retinal tissue they can cause flame

play18:20

hemorrhages and cotton wool spots but

play18:22

the worst case scenario is when they

play18:24

start having to form new blood vessels

play18:25

to get around the damaged blood vessels

play18:27

and that's called proliferative or

play18:29

neovascularization so this is a type of

play18:31

proliferative retinopathy and all of

play18:34

these are nonproliferative retinopathy

play18:36

these patients can start to come in with

play18:37

visual changes and that's pretty bad all

play18:39

right so watch out for patients who

play18:41

start having a bump in their GFR an

play18:43

increase in their alumin watch out for

play18:45

any evidence of macrovascular

play18:47

complications such as neurological

play18:48

deficits angen and St changes and

play18:51

potentially troponin elevations claic

play18:53

ulcers and then again retinopathy with

play18:56

vision

play18:57

changes another complication that could

play18:59

be very significant is neuropathy this

play19:01

is actually really interesting the

play19:03

concept behind this is that glucose

play19:04

whenever it's in really high amounts it

play19:06

gets into your cells and what it does is

play19:08

it can actually increase the amount of

play19:09

sorbitol now sorbitol the problem with

play19:11

this thing is that it can loves to pull

play19:13

water into the cells as you pull a lot

play19:16

of water into the cells via its osmotic

play19:17

kind of PR practic um its osmotic

play19:19

characteristics it can lead to these

play19:21

cells dying because of the osmotic

play19:23

damage when that happens the cells that

play19:25

are really kind of being affected by

play19:27

this is the Schwan cells which are

play19:29

significant to your actual peripheral

play19:30

nervous system so often times these

play19:32

patients can develop what's called

play19:33

neuropathy peripheral neuropathy that's

play19:35

called diabetic

play19:36

neuropathy now ways that this can

play19:39

present is that it Alters The Sensation

play19:40

from the lower extremities and they can

play19:42

develop paresthesias and sometimes in

play19:44

the worst case scenarios they lose all

play19:46

complete sensation to their lower

play19:48

extremities usually in what's called a

play19:49

stock and glove type of

play19:50

pattern the problem with this is if you

play19:53

lose sensation to your lower extremities

play19:55

and as a patient who goes around maybe

play19:57

you step on something you hit your leg

play19:59

against something you start getting

play20:00

sores or ulcers that form on your foot

play20:02

you may not even know that they're there

play20:04

the problem with this is that these

play20:06

diabetic foot ulcers are very high risk

play20:08

for infection especially in a patient

play20:10

who has diabetes why because diabetes

play20:12

accelerates the risk of pad so if a

play20:14

patient has peripheral artery disease

play20:17

they won't give good oxygen to their

play20:18

tissues they have increased risk of

play20:20

ulcers and now this thing can become

play20:22

infected and even potentially progress

play20:23

to gangrenous uh necrosis and that's a

play20:26

very important thing to remember

play20:28

the other concept here is that it also

play20:30

Alters the neurons that Supply the

play20:31

stomach and so these patients may have

play20:34

difficulty being able to generate enough

play20:35

profound contraction of their stomach

play20:37

and empty the contents of their stomach

play20:39

and so because of that they may present

play20:40

with what's called

play20:41

gastroparesis so they may present with

play20:43

nausea vomiting stomach dilation um and

play20:46

this is potentially common as well the

play20:49

last one is what's called orthostatic

play20:50

hypotension this one's due to um kind of

play20:53

an autonomic nervous system neuropathy

play20:56

so you kind of demate some of the

play20:57

autonomic neurons and so what happens is

play21:00

is your sympathetic nervous system is

play21:01

supposed to provide Vaso constriction to

play21:04

your veins and to your arteries if a

play21:06

patient is not getting enough good venoc

play21:08

constriction they're not going to be

play21:09

able to squeeze their veins and return

play21:11

enough blood to their right heart

play21:13

maintain a good Venus return stroke

play21:14

volume blood pressure and they won't be

play21:16

able to profuse their brain as well so

play21:19

because of that if you have a patient

play21:21

who has some type of autonomic

play21:22

neuropathy because you demyen their

play21:24

sympathetic neurons they won't give good

play21:26

venal contriction they won't have good

play21:28

Venus return they won't have a good

play21:29

stroke volume cardiac output blood

play21:31

pressure and they could end up with

play21:32

Syncopy or they could end up whenever

play21:34

they stand up they start getting

play21:35

lightheaded and pre synple so this is

play21:37

very common complications in patients

play21:39

with

play21:40

diabetes we talked a lot about the

play21:42

complications right I think the next

play21:43

thing to go to is okay I have a patient

play21:45

comes in polyurea poly dipsia polyphasia

play21:48

maybe they come in with a hyperglycemic

play21:49

crisis like dka HHS they have common

play21:52

atherosclerotic cardiovascular dis maybe

play21:54

they had a TIA a stroke maybe they also

play21:57

had a heart attack or OC cardial

play21:58

infarction is the proper term maybe they

play22:00

have pulon um they have peripheral

play22:01

artery disease um on top of that they

play22:04

coming in with neuropathy so they have

play22:05

sensory losses they have ulcers on their

play22:07

foot um maybe they have kidney disease

play22:09

so they're having an increased GFR a lot

play22:11

of abum loss um they're having visual

play22:14

changes and now they're having blurry

play22:15

vision and maybe even complete vision

play22:17

loss or retinal

play22:19

detachments in these particular

play22:20

scenarios it's important to consider

play22:22

diabetes as the cause so what we'll do

play22:25

is for these patients is we'll look for

play22:27

findings of hypoglycemia so if they have

play22:30

the polyurea the poly dipsia and the

play22:32

polyphasia or do they have lots of foot

play22:35

ulcers

play22:36

infections um do they have any

play22:38

atherosclerotic cardiovascular disease

play22:40

factors all those things that we talked

play22:41

about if they don't and it's more

play22:44

Insidious then it's kind of important to

play22:46

obtain three particular tests you want

play22:48

to get a fasting plasma glucose level a

play22:51

2hour oral glucose tolerance test this

play22:53

one's a little bit more specific for

play22:54

gestational diabetes but we'll talk

play22:56

about it and then lastly the most clear

play22:59

test is the hemoglobin

play23:00

A1c from these this will give you an

play23:03

idea if the patient has diabetes or not

play23:06

if the fasting plasma glucose level is

play23:07

greater than or equal to 126 milligrams

play23:09

per deal that means that they're living

play23:10

with a high glucose pretty much without

play23:11

any food in them so that's definitely

play23:14

diagnostic if the blood glucose is

play23:16

greater than equal to 200 after you give

play23:18

them a little bit of sugar that's

play23:20

definitely indicative of diabetes and

play23:23

then lastly if their A1C is greater than

play23:24

or equal to 6.5% that tells me that

play23:26

they're living with a high sugar

play23:28

pretty decently high sugar that you can

play23:30

extrapolate over a period of 3 months

play23:32

and that's one of the benefits of A1C

play23:34

it's a little bit better at being able

play23:35

to tell you the longterm effect or at

play23:36

least a three-month time frame of what

play23:38

their sugars have looked

play23:40

like if they have these you have

play23:42

diabetes right you can go further if you

play23:45

want to say I want to see if it's type

play23:47

one or type two oftentimes you can gain

play23:49

that from history but if you want to go

play23:51

the length of determining if it really

play23:52

is type one type two you contain

play23:53

something called a c peptide and

play23:55

antibodies before we talk about that

play23:57

though let's let's say that we have a

play23:58

patient who comes in with polyurea

play24:00

polyphasia polydipsia or other

play24:02

concerning findings that suggest

play24:04

diabetes from that you can get a random

play24:06

plasma glucose and if the random plasma

play24:08

glucose on at least two occasions is

play24:10

greater than or equal to 200 milligrams

play24:12

per DL plus symptoms it's likely

play24:14

diagnostic of diabetes now I'll say that

play24:16

you you're not sure is it type one type

play24:18

two again history usually can elucidate

play24:21

this but if not you can obtain the C

play24:23

peptide often times the antibodies the

play24:25

anti-gad anti-et those are going to be

play24:27

present in type one you're not going to

play24:29

see that really in type two the other

play24:31

thing is the C peptide levels those

play24:33

should be lower generally in a patient

play24:35

who has Type 1 diabetes also look at the

play24:38

history are they less than 30 greater

play24:40

than 40 that also May provide some

play24:41

effect this would suggest more of a type

play24:44

one in the other scenario where I think

play24:47

the patient has type two the antibodies

play24:48

should technically be negative they're

play24:50

going to have more of the

play24:51

characteristics of metabolic syndrome so

play24:54

obesity um low HDL high triglycerides

play24:57

High BP high sugar uh increased waste

play25:00

circumference and often times their C

play25:03

peptide in the initial periods are going

play25:05

to be high so C peptide is kind of like

play25:07

one of the molecules that gets released

play25:09

with insulin and patients who have type

play25:10

two diabetes they release a lot of

play25:12

insulin it's just they are insulin

play25:13

resistant so if they release a lot of

play25:15

insulin they'll release a lot of C

play25:16

peptide if you don't release a lot of

play25:18

insulin you don't release a lot of C

play25:20

peptide all right how do we treat

play25:23

diabetes Well type one they're just not

play25:25

making insulin so you got to give them

play25:27

insulin that's pretty straightforward

play25:29

for this one so there's different types

play25:31

of insulin we'll go through this briefly

play25:33

there is what's called rapid acting

play25:34

insulin in the form of lisbo and aspar

play25:36

lisbo is the more commonly utilized one

play25:39

the duration for these are pretty short

play25:41

so because of that if they're very very

play25:43

short acting the best time to give them

play25:45

is usually um for meals so whenever a

play25:48

person's going to be eating breakfast or

play25:49

lunch or dinner we should be giving it

play25:51

around those times to help them to

play25:53

control that Sugar Spike whenever they

play25:54

eat so again this is best for whenever

play25:56

their patient is going to about to eat

play25:59

the other one is a short acting insulin

play26:02

so this one's going to be the regular

play26:03

insulin its duration is a little bit

play26:05

longer not significantly longer but it's

play26:07

a little bit longer problem with this is

play26:09

it's a little bit too long for a patient

play26:11

you know eating um and it's not long

play26:14

enough that it's going to last an entire

play26:15

day for their basil insulin so really

play26:18

the only time where we really use short

play26:19

acting insulin is in a hypoglycemic

play26:21

crisis um so this is going to be more

play26:23

fitting for a patient who's going to be

play26:24

on an infusion that we can titrate every

play26:26

single hour

play26:28

and so for patients who come in with dka

play26:29

or HHS are very very difficult to

play26:32

control um type 1 diabetes metis we may

play26:35

put them on an insulin infusion to get a

play26:38

a little bit more better control and

play26:40

then we can extrapolate how much insulin

play26:41

they're on on that infusion and then

play26:43

switch them over to a rapid acting and a

play26:46

long acting

play26:47

insulin there's another one it's a

play26:49

little bit cheaper and it's more

play26:50

commonly utilized because of that it's

play26:52

called intermediate acting insulin also

play26:54

known as

play26:55

NPH um and this one humin it can have a

play26:58

little bit of a longer period in

play27:00

comparison to the regular insulin

play27:02

problem is it's not going to last 24

play27:04

hours so this can be used as a basil

play27:06

insulin meaning that you're going to

play27:07

give it and it may give you a pretty

play27:09

good extent of time where the sugars are

play27:11

relatively stable however you're going

play27:13

to have to give probably two doses of it

play27:15

so you may need it twice a day so it's

play27:17

not commonly utilized U but it is a

play27:19

little bit cheaper these are going to be

play27:22

the more commonly utilized one which is

play27:23

the long acting ones garene and damir

play27:26

garene is probably the more one that

play27:28

you'll see um these have no peak they're

play27:30

pretty stable and as you can see here

play27:32

it's kind of got a plateau phase that

play27:33

it's pretty good and it can last a

play27:34

decent amount of time so about 24 hours

play27:37

so to give you a full day length of

play27:39

insulin that's kind of like your

play27:40

Baseline and if you think about this

play27:42

this would be really good for insul that

play27:44

you can give maybe at the end of the

play27:46

night or maybe you can give it around

play27:47

lunchtime around 12:00 and this should

play27:50

give you a very long coverage of the

play27:52

entire 24-hour period so this may seem

play27:55

like a lot you're like okay what am I

play27:57

supposed to to do with this to treat

play27:58

them I don't know I know that if they

play28:00

got really high glucose I'll put them on

play28:01

an insulin Fusion I know that this is I

play28:03

give with the meals I know I could give

play28:04

one of these two potentially with you

play28:06

know once a day or twice a day I don't

play28:08

really understand Zach how do I do this

play28:09

I got you the basic concept here is we

play28:11

use something called a basil blls

play28:12

regimen so we're putting them on an

play28:14

infusion we just monitor this every hour

play28:16

and we titrate to their glucose for

play28:18

these we're going to more commonly base

play28:20

it off of their weight um and their A1C

play28:23

so in a Bas of bus regimen you're going

play28:25

to take their weight and you're going to

play28:27

multiply by a factor this factor is

play28:29

variable so a patient who's like you're

play28:31

just starting them on insulin 3.5 is

play28:33

okay if a patient is has really high A1C

play28:37

you may need a 7 or one and that's

play28:39

something that really depends from

play28:41

Patient to Patient but let's say that

play28:42

you start off with this when you do this

play28:46

this will give you a number that tells

play28:47

you the total amount of insulin that you

play28:48

can give them for a day all right so

play28:51

it's a total daily dose so what I'm

play28:52

going to do is I'm going to split this

play28:53

into two parts the one that I'm going to

play28:55

give them that's going to last them 24

play28:57

hours and the one that I'm going to give

play28:58

them that'll last for particularly

play29:00

whenever they eat so I'm going to split

play29:02

this in half when I split it in half

play29:04

half of it's going to be the glargine

play29:05

dose that's my long acting insulin

play29:07

that'll give me the entire 24-hour

play29:10

period then I'm going to take the other

play29:12

half and that's going to be my lispro

play29:14

dose that's my rapid acting that I'm

play29:16

going to give them with the meals but I

play29:18

have about three meals a day maybe I'm

play29:19

going to eat breakfast lunch and dinner

play29:21

I'm going to take this dose and I'm

play29:22

going to split it up over three meals so

play29:24

maybe it was a total of like yeah I

play29:27

don't know 12 units I'm going to divide

play29:28

that by three and and you know four

play29:30

units at breakfast four units at lunch

play29:32

four units at dinner and then for this

play29:34

one I'm going be going to give 12 units

play29:36

I'll give it around 12:00 and that's

play29:37

going to last me until 12:00 the next

play29:39

day that's the concept behind this the

play29:42

important thing to remember is when you

play29:43

start them on this you should kind of

play29:44

track their glucoses maybe again at

play29:47

breakfast at lunch at dinner and right

play29:49

before you go to bed to make sure that

play29:50

they're appropriately within a good

play29:51

range and you don't have to modify these

play29:53

a little bit but this is how we would

play29:55

treat type 1 diabetes again the

play29:57

alternative is I could say instead of me

play30:00

using garene I could use NPH here it's

play30:03

just I would have to potentially give it

play30:04

twice a day rather than once a

play30:07

day all right what about type two

play30:09

diabetes well they're still making

play30:10

insulin so I don't need to give them

play30:12

insulin there is a couple exceptions

play30:14

where I could but often times we just

play30:16

need to try to improve insulin

play30:18

resistance so often times it is changing

play30:20

up the lifestyle right trying to treat

play30:22

the metabolic syndrome losing weight

play30:24

reducing caloric intake Etc but

play30:27

unfortunately with these patients

play30:28

they're going to require anti-diabetic

play30:30

medications to some degree the most

play30:32

common one that we'll start off with is

play30:33

a biguanide it's metformin It's usually

play30:35

the first line medication so we'll start

play30:38

them on that and then three months what

play30:39

we'll do is we'll get an A1C because

play30:41

it's going to tell me where their sugars

play30:43

have been for at least a 3-month period

play30:45

remember greater than or equal to 6.5%

play30:47

is considered diabetes right at this

play30:50

point I want to just know if they're

play30:51

being better controlled so I'm going to

play30:53

use an arbitrary number such as 7% this

play30:56

is what we've been shown in the the

play30:58

guidelines if a patient gets that A1C

play31:01

though and I see that after I put them

play31:03

on Metformin for three months their A1C

play31:05

is greater than 9.5% there's not a

play31:07

chance in heck that if I put them on a

play31:09

second anti-diabetic medication I'm

play31:11

going to get them from 9.5 down to like

play31:13

less than seven so at this point if it's

play31:16

greater than 99.5% just start them on

play31:19

basil insulin so you're going to put

play31:20

them on something like garene or you're

play31:22

going to put them on something like DLC

play31:23

or NPH potentially and this is going to

play31:26

give you a little bit more extended

play31:27

coverage to try to bring that glucose

play31:29

down and have a basil control of their

play31:33

sugar if the A1C is greater than 7% it

play31:36

means okay I know that I started met

play31:38

foran I'm still not less than 7% I want

play31:41

to get less than 7% That's my goal if

play31:44

I'm not there yet I got to add on a

play31:46

second agent all right so if I'm I'm

play31:48

greater than seven but I'm still less

play31:49

than 9.5 I'm gonna add on a second

play31:52

anti-diabetic all right what's that one

play31:55

there's a lot of them and it's really

play31:57

based upon the patient's underlying

play31:58

diseases are what they're trying to do

play32:01

so let's say that the patient has

play32:03

coronary artery disease they have a

play32:05

history of a Tia or a stroke they have

play32:07

peripheral artery disease in these

play32:09

particular scenarios there is a couple

play32:11

drugs that actually may help with that

play32:13

glyp one agonis stide lorag these

play32:16

potentially can provide a lot of benefit

play32:17

there sglt2 Inhibitors like your flosin

play32:20

these can also be potentially

play32:22

beneficial the other one is if a patient

play32:24

has underlying CHF if a patient has ch

play32:27

HF we have seen that particularly sglt2

play32:30

Inhibitors are very very effective and

play32:32

they can be a part of what's called your

play32:34

guideline directed medical therapy the

play32:36

one that you should never give to a

play32:37

patient with CHF because it's been shown

play32:39

to potentially worsen it is thadine

play32:41

diones so stay away from

play32:44

those if a patient has CKD we know that

play32:46

sglt2 Inhibitors and glip one Agonist

play32:49

are pretty good for these patients if

play32:51

they are looking to lose weight we know

play32:53

that SGL t2s glip 1es and DPP four

play32:57

Inhibitors have been shown to be good

play32:58

for weight loss so if your goal is to

play33:00

treat your Arro or the atherosclerosis

play33:03

related diseases these should be

play33:05

initiated if it's CHF these well this

play33:08

one sorry if it's CKD this one and if

play33:10

it's weight loss it's this one so you

play33:12

notice a trend the most commonly

play33:14

utilized ones here as a second line

play33:16

agent is glyp one agonists or sglt2

play33:19

Inhibitors and maybe a dpp4 inhibitor

play33:22

the other one is if you don't want to

play33:23

have a lot of periods of hypoglycemia

play33:25

because these can cause like neurog glyc

play33:27

pic symptoms you can become diaphoretic

play33:28

you can actually go into a comose state

play33:30

from severe

play33:31

hypoglycemia so it's important to be

play33:33

able to give drugs that you want to do

play33:35

to reduce that risk glip one agonists

play33:38

are really good at not having a lot of

play33:39

hypoglycemia um dpb4 Inhibitors sglt2

play33:42

Inhibitors and thadine Dion so with that

play33:45

being said the one that does have a risk

play33:47

of hypoglycemia and you probably don't

play33:48

want to actually take is

play33:51

sanas the benefits of sulani uras are

play33:53

they a little they are a little bit more

play33:55

cheaper um so that's going to be one one

play33:57

of the reasons why that they could be

play33:58

considered so gide and glide all

play34:01

right so let's say that I start the

play34:04

second antidiabetic and I base it upon

play34:06

one of these particular factors you're

play34:07

seeing a trend though that sglt 2s and

play34:10

glip 1es are really the best in a lot of

play34:12

scenarios here so I start them on one of

play34:14

those I get an A1C in three months and

play34:18

then I check if my A1C is greater than

play34:20

9.5 there's not a chance that adding a

play34:22

third anti-diabetic is going to get me

play34:24

that love to bring the A1C less than 7%

play34:27

start the basil insulin all right get a

play34:29

little bit more Baseline control of

play34:30

their

play34:31

sugars if it is still greater than seven

play34:34

but less than 9.5 I can be a little bit

play34:36

more aggressive and I can add on a third

play34:37

anti-diabetic so I say I started the m

play34:39

at foran A1C is still greater than 7%

play34:42

after 3 months start them on a glip one

play34:44

Agonist A1C still greater than 7% after

play34:47

3 months start them on an sglt2

play34:49

inhibitor if after that in 3 months I

play34:53

check it and their A1C is still greater

play34:55

than 7% you got to then then add on an

play34:57

another uh you got to add on insulin so

play34:59

that's what we would do in this

play35:01

particular scenario of treating a

play35:02

patient with type 2 diabetes start off

play35:04

with metformin go to a second

play35:06

anti-diabetic if you're not meeting your

play35:07

goal then a third anti-diabetic if

play35:09

you're not meeting your goal and then

play35:11

insulin if you haven't met your goal

play35:13

with three anti-diabetics if along any

play35:16

point in that time frame your A1C is

play35:19

greater than 99.5% start them on basil

play35:22

insulin all right the last thing here is

play35:24

treating the complications of diabetes m

play35:27

there is a lot of these but the most

play35:28

concerning ones is dka and HHS so let's

play35:31

talk about how do we treat this well

play35:33

first thing is these patients are

play35:34

severely dehydrated from the osmotic

play35:36

diuresis so because of that you want to

play35:38

replace their their volume losses and

play35:41

often times these are patients that can

play35:42

require like three to four liters of

play35:44

fluid so they should be seen in an ICU

play35:46

often times we start them on an infusion

play35:48

we may give them like a bolus of fluid

play35:50

maybe one or two liters like an a Bolis

play35:51

and then we'll start them at a very high

play35:53

maintenance rate maybe 120 150

play35:55

milliliters an hour the two choices I'd

play35:58

say that are best is half normal saline

play35:59

and LR the only reason why is that

play36:01

normal saline itself can cause a little

play36:04

bit of a normal anti-ap metabolic

play36:05

acidosis and if a patient's already

play36:07

acidotic from dka you can worsen their

play36:10

acidosis so you're going to start giving

play36:11

them some boluses and then start them on

play36:13

a maintenance rate to re replace their

play36:15

actual dehydration the next thing is you

play36:17

have to ask yourself the question I'm

play36:19

about to start insulin for this patient

play36:21

Well's their pottassium so get a BMP

play36:22

check what their pottassium is the

play36:24

reason why is you can't start the

play36:25

insulin infusion unless their po

play36:26

potassium is normal so if I check it and

play36:28

the pottassium is low give them

play36:29

potassium first replace that then after

play36:32

the potassium is normalized then you can

play36:34

go ahead and initiate an insulin

play36:35

infusion and again the type of insulin

play36:38

is not going to be the rapid acting it's

play36:40

not going to be the intermediate the

play36:41

long acting it is the regular insulin

play36:43

all right so in this particular scenario

play36:46

if I start them off on regular insulin

play36:48

here's what we do this for because often

play36:50

times I think there's a misconception of

play36:51

how we give them insulin when we start

play36:54

the insulin infusion we started off at

play36:56

at a particular portion and we're going

play36:59

to continue to up titrate the insulin

play37:02

not to glucose we're titrating it to the

play37:05

Ann Gap so you're going to be monitoring

play37:07

these patients BMP like every two hours

play37:10

so they're going to be getting frequent

play37:11

lab draws you start the insulin infusion

play37:13

their anine Gap is like 20 you get the

play37:16

insulin you check in two hours their

play37:17

anine gap's 18 all right you're kind of

play37:20

bringing the an gap down but if the Ann

play37:23

Gap is still present you need to then

play37:26

increase increase the insulin infusion

play37:28

rate so that you can keep bringing down

play37:30

the anine Gap because insulin is going

play37:32

to start kind of shutting down the

play37:34

ketogenesis process so if the an Gap

play37:37

closed great you don't need to have them

play37:40

on regular in insulin infusion anymore

play37:42

you can just put them over onto the

play37:43

basil bolus and stop the infusion but if

play37:46

their insulin um if their uh anine Gap

play37:49

is still potentially present say that

play37:51

you went from 20 to 18 you have to keep

play37:53

them on the insulin infusion you might

play37:54

even have to increase the rate now if I

play37:57

increase the rate of the insulin I also

play37:59

have to bolish them with more insulin so

play38:02

again start off with fluids check their

play38:05

potassium if it's normal start the

play38:06

insulin infusion check their anine Gap

play38:08

via their BMP every two hours if I check

play38:11

it and it completely normalized it's

play38:12

less than 12 you can stop the infusion

play38:15

you're good and you can just treat them

play38:16

with basil

play38:17

Bolis if you do it and the BMP shows

play38:20

that your an Gap is still elevated you

play38:22

have to increase the rate of your

play38:23

insulin infusion and then rebol them

play38:25

with insulin

play38:27

keep checking their BMP every two hours

play38:31

during that time frame you should also

play38:32

consider maybe getting abgs or vbgs if a

play38:35

patient is severely acidotic a pH less

play38:37

than seven that's really bad and that

play38:39

can actually start altering a lot of

play38:41

problems that can lead to a lot of

play38:42

problems it can lead to you know poor

play38:44

responsive to poor response to vase

play38:46

oppressors it can even worsen a lot of

play38:48

your potassium derangements and so in

play38:50

this situation if the pH is less than

play38:52

seven you should give this patient

play38:53

bicarbonate and that's the only time the

play38:56

other thing is you have to kind of think

play38:58

about this in a patient who has diabetic

play39:01

keto acidosis you're giving them a lot

play39:02

of insulin a lot of insulin that's going

play39:04

to start bringing down their glucose

play39:06

that's not what you're doing it for

play39:07

you're doing it to bring down their keto

play39:09

acidosis but unfortunately it may take

play39:12

some time to bring their keto acidosis

play39:13

down so as you're bringing down their

play39:15

keto acidosis their glucose may be

play39:17

really low and you need to keep giving

play39:19

them more insulin and the problem with

play39:21

that is if I give more insulin I'm going

play39:23

to cause them to become hypoglycemic so

play39:25

if the blood glucose drops to less than

play39:27

200 and your anine Gap is still not

play39:29

completely closed I have to give them

play39:31

sugar in order for me to give them

play39:33

insulin so what you're going to do is

play39:35

you already have them on like 125 or 150

play39:38

of LR or half normal add D5 into it and

play39:41

that'll help to increase their sugar so

play39:43

that you can give them more insulin to

play39:45

bring down their keto acidosis and close

play39:47

their anion gap I know that's a lot of

play39:49

stuff I hope that part made sense for

play39:52

HHS you're actually not going to do an

play39:54

insulin infusion for the keto acidosis

play39:56

you're doing it directly for the

play39:58

patient's hypoglycemia and

play40:00

hyperosmolarity but the same thing these

play40:02

patients are severely volume dehydrated

play40:05

give them IV fluids in the form of LR

play40:06

half normal give them a couple boluses

play40:08

and then start them on an infusion again

play40:11

insulin infusion is for hyperglycemia

play40:13

you actually are going to tight treated

play40:14

every hour off of their glucose level

play40:17

and then the other thing is you're going

play40:18

to check their osmolarity to make sure

play40:19

that you're not dropping them down too

play40:21

quick and then again make sure that

play40:24

you're giving them pottassium because as

play40:25

you give insulin again insulin will

play40:27

cause the shifting of potassium into the

play40:29

cells which can worsen their hypokalemia

play40:31

that's why you never start an insulin

play40:32

infusion if they are hypocam because

play40:34

then we'll start becoming super tacac

play40:36

cardic the other thing that you want to

play40:37

manage for these patients is the more

play40:39

chronic complications such as

play40:40

retinopathy it's more prevention right

play40:42

so you're going to do annual eye exams

play40:44

looking to see if they have any evidence

play40:45

of you know microaneurysms flame

play40:47

hemorrhages hard exat cotton wool spots

play40:49

proliferative Neo proliferative

play40:52

neovascularization and if you do catch

play40:54

that you should actually start again

play40:56

controlling their glucose but more

play40:57

specifically doing things that can

play40:59

prevent further injury because that

play41:00

neovascularization can cause

play41:02

hemorrhaging so oftentimes we'll do VF

play41:05

Inhibitors which will inject right there

play41:07

into the into the actual eye and that's

play41:09

been shown to potentially reduce the

play41:10

proliferation process sometimes you can

play41:12

do phaser laser photocoagulation if the

play41:15

VF is not an option another one is

play41:17

nephropathy we want to be able to catch

play41:19

a patient developing nephropathy um and

play41:21

so if a patient has diabetes you want to

play41:23

do annual urine album and creatinine

play41:25

ratios to see if their alumin is really

play41:27

becoming high in their urine and then

play41:29

check their BMP to see if their GFR is

play41:31

really starting to decline because in

play41:33

these situations we should actually

play41:34

start them on drugs that can protect

play41:36

them from alumin area protect them from

play41:38

CKD and maybe even control their blood

play41:40

pressure so there's two drugs ACE

play41:42

inhibitors or ARB is one of them what

play41:44

they do is they actually help to kind of

play41:46

promote this change in the eperen

play41:48

arterial they actually cause eperen

play41:49

arterial Vaso dilation so they stop

play41:51

constriction and they help to reduce the

play41:53

intraglomerular pressure reduce the GFR

play41:55

and that helps to reduce a lot of the

play41:56

albumin loss unfortunately though if you

play41:58

drop the GFR you can worsen their kind

play42:00

of kidneys a little bit and cause a bump

play42:02

in their creatinine but it's something

play42:03

that you have to use because it has been

play42:05

shown to be nephroprotective reduce

play42:07

albuminuria reduce the progression in

play42:08

CKD and also can treat a patient who has

play42:11

hypertension all right the goal that

play42:14

you're trying to do here is you're

play42:15

trying to make sure they're not dumping

play42:16

enough protein into the urine so the

play42:18

goal is to get that urine abum and

play42:19

cattiny ratio less than 30 you don't

play42:20

want it from 30 to 300 you definitely

play42:22

don't want it greater than

play42:23

300 the neuropathy is all about again

play42:26

making sure that they are very aware of

play42:28

their Sensations so doing annual foot

play42:31

exams with a licensed podiatrist would

play42:33

actually be very good to see if there is

play42:34

any kind of like diabetic ulcers um to

play42:37

also examine to see do they have

play42:38

diabetic ulcers from from neuropathy or

play42:40

do they also have concominant pad that's

play42:43

also caused some ulcers because you want

play42:44

to be able to recognize those before the

play42:46

patient starts having problems the other

play42:48

thing is that they can cause a lot of

play42:50

pain and so for the pain that they have

play42:52

often times gabapentin and cabalin can

play42:54

be alternatives to treat the neuropathic

play42:56

pain um but if they also have

play42:58

concominant depression tcas or snris can

play43:01

be utilized if they have concominant

play43:03

depression atherosclerosis is again a

play43:05

very very important thing because the

play43:07

diabetes has a very high rate of

play43:09

atherosclerosis so because of this the

play43:10

macrovascular complications are really

play43:12

important to prevent so what we should

play43:14

be doing for these patients is getting

play43:15

an annual lipid panel to make sure that

play43:17

we're screening for any incidents of

play43:19

high LDL low HDL and making sure that if

play43:22

we recognize that we start them in the

play43:24

appropriate therapy one of the reason

play43:26

why is again the indication for statins

play43:28

come from the literature that saying if

play43:30

a patient does have diabetes um they are

play43:32

40 to 75 and they have an

play43:34

atherosclerotic cardiovascular disease

play43:36

risk that's greater than you know 10%

play43:38

they're high risk for atherosclerosis

play43:39

and they should probably started be on

play43:40

be started on a

play43:42

Statin the concept here is you just

play43:44

really want to reduce this type of

play43:46

process but also you want to reduce the

play43:48

risk of this plaque rupturing a platelet

play43:49

sticking to it causing a clot on top of

play43:52

that so the other question is is do they

play43:54

have indications for aspirin if a

play43:56

patient has any clinical risk of

play43:58

atherosclerotic cardiovascular disease

play44:00

and you're trying to prevent them from

play44:02

having that aspirin could be a potential

play44:04

indication here but again statins is

play44:06

really something that you have to have a

play44:07

very low threshold to start in a patient

play44:09

with diabetes because again the goal is

play44:11

to try to prevent plaque thrombosis and

play44:13

the complications like a stroke an MI

play44:16

and critical

play44:17

lisia often times if they're 40 greater

play44:20

than that they have diabetes and their

play44:21

atherosclerotic cardiovascular disease

play44:23

risk is greater than 10% you should

play44:25

start them on a stattin and also

play44:26

consider aspirin all right my friends

play44:28

that was a monster lecture on Diabetes I

play44:30

hope it made sense I hope that you guys

play44:32

really did enjoy it love you thank you

play44:34

and as always until next
