Cholesterol is a fatty substance carried in the blood. Too much "bad" (LDL) cholesterol builds up in the walls of the arteries and raises the risk of heart attack and stroke. High cholesterol causes no symptoms and is found only by a blood test. A healthy diet, physical activity and, when needed, medicines can lower it.

Common questions
I am thin. Can I still have high cholesterol?
Yes. Cholesterol also depends on your genes, diet and other conditions. Thin people can have high cholesterol too, so a blood test is the only way to know.
Do I have to take a statin for life?
Statins usually need to be taken long term to keep protecting your heart. If you stop, cholesterol goes back up. Talk to your doctor before making any change.
