Metabolic Syndrome
Michael Lam, MD, MPH

Those who are in the
sub-clinical phase (age 35-45) and clinical phase of aging (age 45 and above)
have a one in three chance of getting this syndrome and not knowing it.
Perhaps the following signs are more recognizable:
feeling sluggish,
physically and mentally, especially after a meal.
Gaining a pound here
and a pound there-and having increasing difficulty losing them.
Having
blood pressure creep up year after year. And finding that the blood
cholesterol, triglycerides, and blood sugar levels are doing the same.
These
are all accepted signs of aging. They are also all of the symptoms of Metabolic
Syndrome.
Metabolic Syndrome can explain why you feel
lousy today -- such as being tired and fuzzy-minded. It can explain why
you have high triglycerides, high cholesterol or high blood pressure, why
you are feeling lousy after meals, and why you are seeing your
health spin out of control without knowing why. It can also explain why
you are aging faster than your peers. More importantly,
Metabolic
Syndrome sets the stage for catastrophic health problems, such as heart
disease, diabetes, Alzheimer's, cancer, and other age-related diseases.
It is estimated that this syndrome
afflicts
over 60 million Americans and one in four adults over age 35. Hypercholesterolemia,
cigarette smoking, hypertension, and obesity are the main culprits for the
development of artherosclerotic coronary artery disease (CAD). However,
these account only for half of the cases of CAD. The other pathologic processes
underlying atherosclerosis remain unknown.
Metabolic Syndrome may be the cause of up to fifty
percent of all heart attacks. It is an epidemic of massive proportion.
How do you develop Metabolic
Syndrome?
Metabolic Syndrome
develops slowly over time, often
over a course
of 20 years or more. It is the
end result from years (often decades) of taking in
a modern day diet high in refined carbohydrates such as breads, starches
and sweets. These foods, once taken, trigger a rapid increase
in blood sugar levels, and the body responds by raising levels of insulin
secretion that in turn helps to move the sugar out of the blood stream into
the cells. Insulin is a hormone secreted by the pancreas. It helps the body
utilize glucose (blood sugar) by binding with receptors on cells like a
key would fit into a lock. Once the key - insulin - has unlocked the door
of the cell, the glucose passes from the blood into the cell. Inside the
cell, glucose is either used for energy or stored for future use in the
form of glycogen in liver or muscle cells.
The more carbohydrates you eat, the more your pancreas releases insulin
to lower the excessive blood sugar. This is especially so with simple or
refined carbohydrates that are converted into sugar quickly (the high-glycemic
index foods like white bread and white flour) once inside your body. While
insulin levels rise and fall with each meal and is part of the normal metabolic
process, chronic carbohydrate overload causes chronic insulin overload.
The cells of the body, be they the muscles or the fat tissues, recognize
that
excessive sugar is toxic. They
try to shut down the influx of sugar into the cells and therefore go through
a down-regulation process to resist the command of insulin. This state is
called insulin resistance. The pancreas, in response to the insulin resistance
and resulting lowered transport of glucose out of the blood stream to the
cell, puts out even more insulin in order to avoid too high a blood sugar
level. This
compensatory increase in insulin output continues until the pancreas
fails to keep up. Some people produce two, three or four times
the normal amount of insulin. Yet, because the cells have lost their sensitivity
to insulin, they require even more of it to maintain normal glucose levels.
In advanced stages of insulin resistance, when the pancreas becomes exhausted
and can no longer maintain the insulin production, insulin production drops,
resulting in adult onset diabetes mellitus (also called type 2 diabetes).
Insulin resistance plus compensatory hyperinsulinemia is nature's way of
preventing the evolution into type 2 diabetes. It is often referred
to as a pre-diabetic state.
As long as there is insulin resistance, the blood sugar and blood
insulin levels are both high. Over time, high blood sugar and
high insulin cause a myriad of destructive damages to almost every tissue
they touch. It is important to recognize while insulin resistance or high
blood sugar is each bad for health on its own, it takes both insulin resistance
and compensatory hyperinsulinemia, to result in the various manifestations.
These manifestations represent the
resultant damage and surface as a compilation of symptoms representative
of multi-system dysfunction. This includes the cardiovascular system, muscular
system, kidney system, reproductive system, and lipid metabolic system,
just to name a few. These symptoms, when grouped collectively in a setting
of insulin resistance, is called Metabolic Syndrome. It can go undetected for up to 40 years, and a family
history of type 2 diabetes, CHD, or hypertension increases the risk for
Metabolic Syndrome.
Metabolic Syndrome as explained
by Dr Reaven
Metabolic Syndrome was first discovered by Stanford University Professor
and researcher Gerald Reaven, MD. In 1988, he first presented the results
of twenty years of study that showed that the effect of an array of changes
around a little known medical condition called insulin resistance to increased
heart disease.
In his book
Metabolic Syndrome, Dr Reaven describes the condition
as follows:
This deadly heart ailment begins in the bloodstream, shortly after we
eat. That's not a startling idea, for we know that eating fatty or cholesterol-laden
foods can be bad for our hearts. However, the Metabolic Syndrome culprit
isn't red meat or butter, it's carbohydrates. Yet these carbohydrates are
reluctant, inadvertent offenders.
Before entering the body proper, our food is broken down into various constituent
parts in the intestine. One of these is glucose (blood sugar) from carbohydrates.
Upon entering our cells, some of the glucose is put right to work providing
the energy that cells need to perform their various tasks. The rest is stored
in certain cells for later use. But the glucose doesn't simply flow into
the storage cells. Instead, it must be guided in by insulin, a protein secreted
by the pancreas.
Insulin acts like a shepherd, herding its precious flock into the cellular
"corrals". Unfortunately, in many of us, glucose behaves like a group of
errant sheep, stubbornly refusing to go where the shepherd directs. When
that happens, the pancreas pumps out more and more insulin. That's the biochemical
equivalent of sending out more and more "shepherds" to get the "sheep" into
the "corrals". Imagine hundreds of shepherds chasing thousands of sheep
across a pristine field covered with thick, beautiful green grass. Those
hundreds of feet and thousands of hoofs will quickly tear up the field,
ripping out or flattening down clumps of grass. Soon, the field that once
looked so green and lush will be trampled and scarred, brown and dirty.
Something similar happens inside your body when glucose refuses to move
into the storage cells at the insulin's command. The interior linings of
your arteries, like the grassy field, are "ripped" and "trampled" as the
body attempts to overcome this problem.
Eventually, the insulin "shepherds" corral the glucose, and order is restored
in the body. But all is not well, for the "field" (the lining of your coronary
arteries) has been damaged, and there's other damage, as well. This damage
sets the stage for heart disease.
