Cholesterol is a fat-like substance that your body produces naturally. The liver produces most of the cholesterol and its concentration varies greatly depending on your diet.
Your body needs cholesterol to work properly and it uses it to produce hormones, vitamin D and other substances that aid digestion. However, if there is a high cholesterol concentration circulating in your blood, it builds up on the walls of your arteries, causing a disease known as atherosclerosis, which increases risks of cardiovascular disease.
Cholesterol is carried through your bloodstream by particles called lipoproteins. When the level of these particles increases, they deposit on the artery walls, causing the artery to clog and stop blood circulation, thus high cholesterol levels become the number 1 risk factor of cardiovascular disease.
Types of cholesterol
It is important to know that there are two main cholesterol types: high density or HDL cholesterol and low density or LDL cholesterol.
