Also known as hypercholesterolemia, high cholesterol is a condition where increased amounts of lipid-like substances called cholesterol (fats) accumulate in the blood. There are two main types of cholesterol; the most dangerous is LDL (low-density lipoprotein). Oxidized LDL can slowly build up in the walls of your arteries and may eventually lead to heart disease, heart attack or stroke. HDL (high-density lipoprotein) or “good cholesterol” helps recirculate LDL in order to eventually expel it from your body.
Cholesterol comes from two sources: your body, where it's naturally made, and from the food you eat. Dietary cholesterol does not translate directly to blood cholesterol, however foods containing this type of fat should be consumed in minimal quantities, if at all.
Like most conditions involving the heart, the best course of treatment for high cholesterol includes weight loss, exercise and a healthy diet low in saturated fat. There is also medication that can help lower cholesterol
