Treatment of high cholesterol is important to help lower your risk of heart attack and stroke. The first line of treatment is diet and exercise. A low fat, low cholesterol diet will lower your LDL or bad cholesterol. Exercise can help to raise your HDL, the good cholesterol. If blood cholesterol is still elevated, physicians will commonly use medication to lower cholesterol. The most common medication used are the statins, which lower production of cholesterol from the liver.
