'''Cholesterol''' is a waxy, fat-like substance that occurs naturally in all parts of the body. The body needs some cholesterol to work properly but if there is too much in the blood, it can stick to the walls of the [[arteries]]. This is called [[plaque]]. Plaque can narrow the arteries or even block them causing [[atherosclerosis]]. | '''Cholesterol''' is a waxy, fat-like substance that occurs naturally in all parts of the body.
