Cholesterol

Cholesterol is a waxy, fat-like substance that occurs naturally in cell walls and cell membranes throughout the body. Your body uses cholesterol to make many hormones. It also uses it to make vitamin D and the bile acids that help digest fat.

Where problems arise is when there is excess cholesterol in the bloodstream. Cholesterol deposited by LDL leads to a narrowing of the blood vessels.

If this occurs, the excess can deposit in the arteries of the heart, which could cause a stroke or heart disease. This is called atherosclerosis. That is why LDL is known as "bad cholesterol."

Independence of blood vessels and blood vessels' ability to regulate blood pressure is promising. If there is not enough oxygen carrying blood passing through the narrowed arteries, the heart may give you a pain that is called angina.

Cholesterol Range


Cholesterol levels are sustained in milligrams per deciliter (mg / dL). The National Cholesterol Education Program developed the following classifications for people over the age of 20 who do not have heart disease:

1. Cholesterol Normal: Total blood cholesterol is less than 200 mg / dL; LDL is less than 130 mg / dL.

2. High Cholesterol: The total level is between 200 and 239 mg / dL or LDL is from 130 to 159 mg / dL.


3. Very High Cholesterol in the blood: The total level is greater than 240 mg / dL or LDL is 160 mg / dL or more. 
For patients with heart disease, the LDL above 100 mg / dL is too high. 
Also, an HDL level below 35 mg / dL is considered low and increases the risk of heart disease.

High Cholesterol Causes

High total and LDL cholesterol, along with low HDL cholesterol, can increase the risk of heart disease, they are among several other risk factors. These include  smoking, high blood pressure, diabetes, obesity and physical inactivity. If any of this is present in addition to elevated blood cholesterol, the risk of heart disease is even higher.
