How diabetes destroys the human body
Summary
TLDRType 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.
Outlines
🚨 Understanding Type 2 Diabetes and Pre-Diabetes
This paragraph explains the prevalence and risks of type 2 diabetes and pre-diabetes, which can lead to severe health complications like heart disease and stroke. It details how diabetes affects various parts of the body, particularly through the mishandling of glucose by the body. The role of insulin, produced by the pancreas, in aiding the absorption of glucose by cells is emphasized. The paragraph also discusses insulin resistance, hyperinsulinemia, dyslipidemia, and the impact on lipid and lipoprotein levels. It outlines the progression from insulin resistance to beta cell dysfunction, leading to hyperglycemia and the onset of pre-diabetes and diabetes. The consequences of untreated diabetes, such as damage to blood vessels and the risk of complications like neuropathy and atherosclerosis, are also covered.
🛑 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.

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
