Having high blood cholesterol puts you at risk for heart disease, the leading cause of death in the United States. About 1 of every 6 adult Americans has high blood cholesterol.
Cholesterol is a waxy, fat-like substance that your body needs. But, when you have too much in your blood, it can build up on the walls of your arteries. This can lead to heart disease and stroke.
There are no symptoms of high cholesterol. Many people have never had their cholesterol checked, so they don’t know they’re at risk. A simple blood test can tell you your level. The good news is that there are steps you can take to prevent high cholesterol—or to reduce your levels if they are high.
