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

High cholesterol is a condition in which there are too many lipids (fats) in the blood. Cholesterol is a type of lipid, and it helps to keep your body healthy by helping to make hormones and other substances. However, if you have too much cholesterol in your blood, it can build up on the walls of your arteries and cause them to narrow. This can lead to heart disease or stroke.
