Sample Query & Answer

About "Cholesterol"

Cholesterol is a waxy substance found in the blood, and it is essential in building healthy cells when it is at normal levels. It is present in all the cells of the body and helps in producing hormones and the synthesis of vitamin D. The two types of cholesterol are:

1. Low-density lipoprotein (LDL) – Otherwise called bad cholesterol, as it builds up in the walls of the blood vessels and causes atherosclerosis.
2. High-density lipoprotein (HDL) – It is also called good cholesterol, as it takes excess cholesterol back to the liver.

Higher concentration of cholesterol in blood puts an individual at risk for angina, heart attack, and stroke.
