I've been told that I have a high cholesterol level. What does this mean?

High cholesterol is a risk factor for heart disease. Cholesterol is a waxy substance found in the blood and other body fluids. It is made by the liver and is essential for many bodily functions, including brain development and hormone production. Too much cholesterol can be harmful, however, as it can build up in the arteries and cause blockages. This can lead to heart attacks or strokes.
