Cholesterol — what is it?

Cholesterol is found in the fats in your blood and is a waxy substance that your body needs to build healthy cells. However high cholesterol levels can increase your risk of heart disease. There are two types of cholesterol, LDL and HDL. In simple terms, LDL is considered the ‘bad’ cholesterol. LDL carries cholesterol from your liver to the cells that need it, and if there is too much cholesterol for the cells to use, it can build up as plaque on the artery walls. This can contribute to heart disease or even stroke. VLDL (very low density lipoproteins) is similar to LDL in that it contains mostly fat and carries another type of fat, triglycerides, in the blood. Excess calories, alcohol, or sugar in your body are converted into triglycerides and stored in fat cells throughout your body.
