What Is HDL and LDL Cholesterol?

Video Topic : This video explains the difference between HDL and LDL cholesterol. It also reveals what may occur when there are high levels of LDL in the body.
LDL may stick to an artery's inner wall causing the build up of plaque, affecting blood flow. When an artery stiffens and constricts, aneurysm, heart attack, and stroke can occur.


Also called: HDL, Hypercholesterolemia, Hyperlipidemia, Hyperlipoproteinemia, LDL

Cholesterol is a waxy, fat-like substance that occurs naturally in all parts of the body. Your body needs some cholesterol to work properly. But if you have too much in your blood, it can combine with other substances in the blood and stick to the walls of your arteries. This is called plaque. Plaque can narrow your arteries or even block them.

High levels of cholesterol in the blood can increase your risk of heart disease. Your cholesterol levels tend to rise as you get older. There are usually no signs or symptoms that you have high blood cholesterol, but it can be detected with a blood test. You are likely to have high cholesterol if members of your family have it, if you are overweight or if you eat a lot of fatty foods.

You can lower your cholesterol by exercising more and eating more fruits and vegetables. You also may need to take medicine to lower your cholesterol.
