How diabetes destroys the human body

Summary

Type 2 diabetes and pre-diabetes are prevalent conditions that can lead to severe health complications, including heart disease and stroke, which are the leading causes of death and disability in the United States. These conditions arise from the body's mishandling of glucose, a sugar molecule derived from food. The pancreas produces insulin to help cells absorb glucose, but when the body becomes resistant to insulin, it requires more of it, leading to hyperinsulinemia. Over time, this resistance can lead to dyslipidemia, where harmful lipids and lipoproteins accumulate in the blood, and to beta cell dysfunction, resulting in insufficient insulin production and hyperglycemia. If untreated, these conditions can cause significant damage to blood vessels, leading to neuropathy, atherosclerosis, and potentially life-threatening conditions such as heart attacks and strokes. The video emphasizes the importance of understanding and managing these conditions to prevent serious health issues.

Q & A

What are the potential complications of type 2 diabetes and pre-diabetes?

Complications can include heart disease, stroke, vision problems, loss of limb sensation, liver and kidney disease, and an increased risk for stroke and heart attack.

How does the body normally use glucose after a meal?

Glucose, a sugar molecule, is absorbed from the food and transported through the blood to be used by the body's cells for energy.

What is the role of insulin in the body's glucose metabolism?

Insulin, produced by the pancreas, helps liver, fat, and muscle cells absorb glucose from the blood.

What is insulin resistance and how does it relate to diabetes?

Insulin resistance is a condition where the body's cells don't respond well to insulin, necessitating higher amounts for glucose utilization, which can lead to hyperinsulinemia and is a precursor to diabetes.

How does high insulin levels affect lipid and lipoprotein production in the body?

High insulin levels can lead to increased production of bad cholesterol particles (VLDL) and contribute to dyslipidemia, a condition characterized by abnormal lipid levels in the blood.

What is the role of adiponectin in relation to insulin resistance?

Adiponectin is a hormone released by fat cells that aids in breaking down lipids, particularly free fatty acids. It is often low in individuals with obesity or insulin resistance, indicating a risk for developing type 2 diabetes.

What happens to the pancreas when there is a strain on its beta cells?

The pancreas may become overworked, leading to the death of beta cells that produce insulin. This can result in beta cell dysfunction and an eventual insulin deficiency.

Define hyperglycemia and how it is related to diabetes.

Hyperglycemia is a condition where there is too much glucose in the blood. It is a defining characteristic of pre-diabetes and diabetes, occurring when the body can't produce enough insulin or when cells become resistant to it.

How does hyperglycemia affect the body's energy provision?

When insulin levels are low, liver and muscle cells start to release stored glucose to provide energy. However, without adequate insulin and with insulin resistance, more glucose is released, exacerbating hyperglycemia.

What are the markers of glycemic control and when are they measured?

Markers of glycemic control, such as consistently high glucose levels, are typically measured during fasting periods when blood sugar should be low.

How do excess lipids and lipoprotein particles contribute to cardiovascular diseases?

Excess lipids and lipoprotein particles can build up, forming plaques in blood vessels, leading to atherosclerosis. This can obstruct blood flow, causing conditions like neuropathy, and increase the risk of heart attack or stroke.

What is atherosclerosis and how does it impact the body's organs?

Atherosclerosis is a condition where plaque builds up in the arteries, which can restrict blood flow and lead to organ damage, including heart disease, stroke, kidney, or liver disease.

🛑 Complications of Untreated Diabetes

The second paragraph delves into the serious complications that can arise if diabetes is left untreated. It describes how excess lipids and lipoprotein particles can lead to plaque buildup in blood vessels, causing restricted blood flow and potentially resulting in conditions like neuropathy, where nerves are damaged, leading to numbness, weakened muscles, and even amputation. The paragraph also explains how plaque buildup in larger vessels can cause atherosclerosis, which increases the risk of cardiovascular disease, heart attacks, and strokes. Additionally, it touches on the broader impact of atherosclerosis on end-organ damage, such as kidney or liver disease.

Keywords

💡Type 2 Diabetes

Type 2 diabetes is a chronic condition that affects the way the body processes blood sugar (glucose). It is characterized by insulin resistance, where the body's cells do not use insulin properly, leading to high blood sugar levels. The condition is a major risk factor for heart disease, stroke, kidney disease, and other serious health complications. In the video, it is mentioned as a condition that can be avoided and reversed, highlighting its importance in the discussion.

💡Pre-diabetes

Pre-diabetes is a state where blood sugar levels are higher than normal but not high enough to be classified as type 2 diabetes. It is a warning sign that one is at risk of developing diabetes if lifestyle changes are not made. The video emphasizes that pre-diabetes can lead to serious health issues, but it is also a condition where risk can be reversed with proper intervention.

💡Insulin Resistance

Insulin resistance is a condition in which the body's cells become less responsive to the hormone insulin, which is needed to absorb glucose from the bloodstream. This resistance leads to higher levels of insulin in the blood, which in turn can cause the pancreas to overwork and eventually fail to produce enough insulin. In the video, it is identified as the primary mechanism that leads to pre-diabetes and diabetes.

💡Glucose

Glucose is a type of sugar that is the primary source of energy for the body's cells. After a meal, food is broken down into glucose, which enters the bloodstream and is used for energy. In the context of the video, glucose is central to understanding diabetes, as the body's mishandling of glucose is the root cause of the disease.

💡Hyperinsulinemia

Hyperinsulinemia refers to a condition where there is an abnormally high level of insulin in the blood. This can occur when the body is resistant to insulin and the pancreas compensates by producing more insulin. The video mentions hyperinsulinemia as a marker of initial risk for developing diabetes, indicating high insulin levels in the presence of insulin resistance.

💡Dyslipidemia

Dyslipidemia is a condition characterized by abnormal levels of lipids (fats) and lipoproteins in the blood. High levels of these particles can be dangerous, as they can build up in blood vessels and contribute to cardiovascular disease. In the video, dyslipidemia is discussed in relation to diabetes, as elevated insulin levels can lead to an increase in bad cholesterol particles in the bloodstream.

💡Adiponectin

Adiponectin is a hormone that is released by fat cells and helps in the breakdown of lipids, particularly free fatty acids. In the context of the video, low levels of adiponectin are associated with obesity or insulin resistance and are often found in patients before they develop type 2 diabetes. It serves as an insightful clue on the extent of insulin resistance.

💡Beta Cell Dysfunction

Beta cell dysfunction refers to the impaired ability of the beta cells in the pancreas to produce insulin. Over time, as the pancreas becomes overworked due to insulin resistance, these cells begin to die, leading to a decrease in insulin production. The video explains that this dysfunction is a critical step towards the onset of prediabetes and diabetes.

💡Hyperglycemia

Hyperglycemia is a condition where there is too much glucose in the blood. This occurs when the body cannot produce enough insulin or when cells become resistant to the effects of insulin. The video describes hyperglycemia as a defining characteristic of pre-diabetes and diabetes, where high levels of glucose remain in the blood due to inadequate insulin levels.

💡Neuropathy

Neuropathy is a type of damage to the nerves that can result from high blood sugar levels, as seen in diabetes. It can cause numbness, impaired healing, muscle weakness, and even amputation in severe cases. The video discusses neuropathy as a serious complication that can affect various functions, including vision, blood pressure, and heart rate.

💡Atherosclerosis

Atherosclerosis is a condition where plaque builds up inside the arteries, which can restrict blood flow and lead to cardiovascular disease, heart attack, or stroke. The video highlights atherosclerosis as a consequence of diabetes, where the buildup of lipids and lipoprotein particles in the blood vessels contributes to the hardening and narrowing of the arteries.

Transcripts

type 2 diabetes and pre-diabetes are

conditions that affect millions of

people they can lead to heart disease

and stroke which are the first and third

leading causes of death and disability

in the united states respectively

people with diabetes and pre-diabetes

can develop problems with their vision

and lose feeling in their limbs they may

develop liver and kidney disease and are

at risk for stroke and heart attack

however type 2 diabetes and pre-diabetes

can be avoided and risk can be reversed

what is diabetes

diabetes is a complex disease that

affects many parts of your body but is

caused by the way your body mishandles

the food you eat

after a meal food is broken down into

sugar molecules called glucose glucose

travels through the intestines into the

blood where it is carried to all

different areas of the body and is used

for energy

there are some parts of your body that

need help absorbing the glucose

molecules and require a special hormone

called insulin

insulin is formed in the pancreas and

circulates in the blood with glucose to

the cells that need help specifically

liver cells fat cells and muscle cells

when the body develops resistance to

insulin increasing amounts of insulin

are necessary for it to be able to

utilize glucose

initially during insulin resistance your

pancreas will work on overtime to

produce more insulin

this can happen even when your glucose

levels are relatively normal

if tests reveal abnormally high insulin

levels a condition called

hyperinsulinemia along with insulin

resistance markers your body shows

initial risk for developing diabetes

lots of insulin in the blood also

affects the production of lipids and

lipoproteins which are the small

particles that are broken down from

cholesterol molecules and fat products

called triglycerides

these particles are small enough to

travel in your bloodstream but can be

dangerous in large amounts when they

build up in your blood vessels

in the presence of elevated levels of

insulin your body especially your liver

releases bad cholesterol particles such

as vldl and the higher your insulin

levels the more bad cholesterol

particles are circulating in your

bloodstream a condition called

dyslipidemia furthermore adiponectin a

hormone released by your fat cells that

helps break down lipids in particular

free fatty acids is often low in obese

or insulin resistant patients prior to

developing type 2 diabetes

while such lipid and lipoprotein markers

are traditionally tested to measure

cholesterol they also provide insightful

clues on the extent of insulin

resistance

after a while the pancreas will become

overworked and the special beta cells

that produce insulin will begin to die

some tests will measure how well your

beta cells function and if they are

showing strain

beta cell dysfunction means that your

body can no longer make enough insulin

to help your cells take up glucose for

energy and high levels of glucose will

remain in your blood a condition called

hyperglycemia

when insulin levels are low your body

may react in a number of ways

some of the cells that use insulin to

control glucose levels have the ability

to store glucose

liver and muscle cells will begin to

release stored glucose when insulin

levels are low in order to provide the

body energy

without adequate levels of insulin in

the presence of insulin resistance more

and more glucose is released into the

bloodstream and the effects of

hyperglycemia are heightened

markers of glycemic control are usually

measured during periods of fasting when

your blood sugar should be low

test results that demonstrate

consistently high glucose levels are the

defining characteristic of pre-diabetes

and diabetes

to summarize how diabetes develops let's

review the main features

high insulin levels mark the beginning

of insulin resistance the primary

mechanism that leads to pre-diabetes and

diabetes

abnormal levels of lipids lipoproteins

and the hormone adiponectin may further

indicate insulin resistance

a drop in insulin production by the

pancreas occurs from strain on the

hormone-producing beta cells and beta

cell dysfunction eventually leads to an

insulin deficiency

without adequate levels of insulin your

body's ability to control glucose levels

is disrupted and glucose levels increase

defining the onset of prediabetes and

diabetes

too much glucose circulating in your

blood hyperglycemia and too many harmful

lipids circulating in your blood

dyslipidemia are two conditions that are

characteristic of prediabetes and

diabetes left untreated they cause

serious damage to the blood vessels

leading to a variety of complications

excess levels of lipids and lipoprotein

particles can build up to create a

plaque in your blood vessels

this is heightened in the presence of

excess glucose molecules and free fatty

acids

due to blockage in your vessels blood

cannot circulate to your limbs and the

nutrients and oxygen carried by your

blood cannot nourish your body's

extremities

build up causes the vessels to expand

and squeeze the nerves that course

alongside them

leading to a condition called neuropathy

damaged nerves can cause numbness and

keep you from healing normally they can

cause your muscles to weaken and

eventually atrophy sometimes requiring

amputation and you may experience

sensory changes including blindness

involuntary functions such as blood

pressure and heart rate and even sexual

function may become abnormal as a

symptom of neuropathy

in large vessels like those supplying

your heart and your brain plaque buildup

leads to a condition called

atherosclerosis

over time the plaque can grow and

rupture which can cause cardiovascular

disease or a heart attack or in the

brain can lead to a stroke

atherosclerosis further contributes to

end-organ damage like kidney or liver

disease
