Cholesterol is a waxy, fat-like substance that your body needs. When you have too much cholesterol in your blood, it can build up on your artery walls. Too much cholesterol puts you at risk for heart disease and stroke, two leading causes of death in the United States. But you can take steps to manage your cholesterol levels and lower your risk.
There are no signs or symptoms of high cholesterol. Getting your cholesterol checked with a simple blood test is the only way you can know if you are at higher risk for cardiovascular disease.
