High-density lipoprotein, or HDL, is the "good" cholesterol and acts as a transport system by removing the excess cholesterol in the blood and carrying it to the liver for elimination. Cholesterol helps with the structure of cells, production of hormones and helps produce energy, according to MayoClinic.com. The higher the HDL cholesterol number, the lower your risk of atherosclerosis or coronary heart disease. HDL is one measurement in a complete lipid profile that helps your physician determine your overall risk of developing heart disease.
Low HDL Level
HDL cholesterol level less than 40 milligrams per deciliter of blood, or mg/dL, places men in the major risk factor category of heart disease by the American Heart Association standards. Changing your lifestyle and habits is an option for increasing your HDL level. If you smoke, quitting smoking can increase HDL by up to 10 percent, reports MayoClinic.com. In addition, losing weight by following a healthy diet and increasing your physical activity, such as performing exercise five times a week for 30 minutes, may help you increase the "good" cholesterol, while reducing the "bad" cholesterol. MayoClinic.com notes that for every six pounds you lose, you might increase HDL levels by 1 mg/dL.
Medium HDL Level
HDL levels that fall in the 40 mg/dL to 50 mg/dL range places men at risk for heart disease. While you are not at a major risk factor, cholesterol buildup in the arteries may increase your blood pressure and make daily activities more difficult to perform. Increasing your "good" cholesterol levels starts with a heart-healthy diet and exercise. Limiting your daily fat intake to 25 to 35 percent, and decreasing your saturated fat to less than 7 percent daily from calories, may help you to raise your HDL cholesterol. In addition, avoid items that contain saturated and trans fat, while focusing on monounsaturated and polyunsaturated fats that help improve HDL. Some heart-healthy foods include whole grains, nuts and fish.
High HDL Level
HDL cholesterol level that is 60 mg/dL is optimal, and gives you protection against heart disease. According to the Lab Tests Online website, a value greater than 60 mg/dL is similar as a negative risk factor. However, having an optimal HDL level is not the only consideration taken when you are undergoing diagnosis of heart disease. Lab Tests Online reports that several studies show the total opposite, and that a higher HDL level may result in a higher risk of coronary artery disease in some people, but additional research information is required to support this claim.
