Lowering Your Cholesterol Is Important!

Background Cholesterol History

Cholesterol has been around for thousands of years. It’s a natural function of the human body. The modern story of cholesterol and how it affects us today, actually began during a government study in 1951.

The Pentagon sent pathologists to Korea to examine the bodies of servicemen who lost their lives during the war. Autopsies were conducted on 2,000 soldiers.

The results were astounding to the medical community of that time. Normally, no one under 35 dies of coronary heart disease. Remember, this was 1951! 

An Interesting Cholesterol Statistic

More than 75 percent of the soldier had yellow deposits of atherosclerotic plaque on their artery walls. The average age of these soldiers was 21 contradicting the assumption that such artery clogging deposits were only prevalent in older men.

The results of the Army pathologists rocked the medical community. Prior to these autopsies, doctors had no idea how early the process of heart disease began.

Not long after this discovery, a name was given to the major contributor to the buildup of plaque and to heart disease risk – cholesterol. More recent studies have shown that for every 1 percent drop in cholesterol levels, there is a 2 percent decrease in the risk of a heart attack.

More Cholesterol Information

Since those original studies, the risk of heart disease stemming from cholesterol has exploded. In 2002 it was estimated that 107 million American adults now have a blood cholesterol level high enough to require medical advice. Unfortunately, the numbers keep rising.

Despite this epidemic problem, there is good news. You can do something about the problem and that’s what this guide is all about. In plain English, we will take a laymen’s look at cholesterol, the causes, effects and what you can do to reverse the negative impact it has on your personal health.

As mentioned above, cholesterol in and of itself, is a natural function of the human body. Every living being requires a certain amount of fat to exist. Like everything in nature, it only becomes a problem when there is an imbalance.

The processing of fat begins when it gets absorbed in the intestines. From there it heads to the liver. The fat requires a delivery system to the rest of the body to be used immediately but also to be stored in fat cells for future use.

In order for the fat to enter the delivery system, while it is in the liver it is split into two different types of fat, cholesterol and triglycerides.

Once this transformation takes place, the two types of fat (cholesterol and triglycerides) are packed into vehicles for carrying the fat to the fat cells throughout the body using the bloodstream. These vehicles are called lipoproteins.

You need to know about Lipoproteins

There are three types of lipoproteins:

1. Very Low Density Lipoproteins (VLDL)

2. Low Density Lipoproteins (LDL)

3. High Density Lipoproteins (HDL)

Under normal circumstances, the bloodstream does a very efficient job of carrying the LDL and HDL Lipoproteins throughout the body.

Cholesterol is a waxy, fat like substance that presents itself naturally in cell walls and membranes everywhere in your body.  Your body uses cholesterol to produce many hormones.  It also uses it to produce vitamin D and the bile acids that help to digest fat.

Where problems arise is when there is an over abundance of cholesterol in your bloodstream.  The cholesterol deposited by the LDL leads to a narrowing of the blood vessels.

If this occurs, the excess can be deposited in the arteries of the heart which could result in stroke or heart disease.  This is called atherosclerosis.  This is why LDL is known as “bad cholesterol.”

HDL usually collects the bad cholesterol and takes it back to the liver.  That’s why HDL is known as “good cholesterol.”

Cholesterol contributing to heart disease

Cholesterol is not the only cause of heart disease, but it is a contributing factor.  Here’s how it works.

Cholesterol can only attach to the inner lining of the artery if it has been damaged. 

Once the lining of the artery is damaged, white blood cells rush to the site followed by cholesterol, calcium and cellular debris.  The muscle cells around the artery are altered and also accumulate cholesterol.

The fatty streaks in the arteries continue to develop and bulge into the arteries.  This cholesterol “bulge” is then covered by a scar that produces a hard coat or shell over the cholesterol and cell mixture.  It is this collection of cholesterol that is then covered by a scar that is called “plaque.” 

The buildup of plaque narrows the space in the arteries through which blood can flow, decreasing the supply of oxygen and nutrients.  This cuts down the supply of blood and oxygen to the tissues that are fed by that blood vessel. 

Cholesterol Causing Other Dangerous Effects

The elasticity of the blood vessel is reduced and the arteries’ ability to control blood pressure is compromised.  If there is not enough oxygen carrying blood passing through the narrowed arteries, the heart may give you a pain that is called angina.

The pain usually happens when you exercise because at that time your heart requires more oxygen.  Usually it is felt in the chest or the left arm and shoulder, although it can happen without any symptoms at all.

Plaque can vary in size as well as shape.  All through the coronary arteries you can find many small plaques that cover less than half of an artery opening.  Some of these plaques are completely invisible in the tests that doctors use to identify heart disease.

The medical community used to think that the primary concern was the larger plaques.  They thought these posed a greater threat because of their size and that they were more likely to cause a complete blockage of the coronary arteries.

While it is true that the larger plaques are more likely to cause angina, it is the smaller plaques that are packed with cholesterol and covered by scars that are more dangerous.  They are considered unstable and prone to ruptures or bursting releasing their load of cholesterol into the bloodstream.  This causes immediate clotting within the artery.  If the blood clot blocks the artery totally, it will stop the blood flow and a heart attack occurs. 

The muscle on the farter side of the occurring clot fails to get the oxygen it needs and begins to die.  This kind of damage can be permanent.
