Source: MedlinePlus Health Topics, U.S. National Library of Medicine
What is cholesterol? Cholesterol is a waxy, fat-like substance that's found in all the cells in your body. Your liver makes cholesterol, and it is also in some foods, such as meat and dairy products. Your body needs some cholesterol to work properly. But having too much cholesterol in your blood raises your risk of coronary artery disease . What are HDL and LDL? HDL and LDL are two types of lipoproteins.They are a combination of fat (lipid) and protein. The lipids need to be attached to the proteins so they can move through the blood. HDL and LDL have different purposes: HDL stands for high-density lipoproteins. It is sometimes called the "good" cholesterol because it carries cholesterol from other parts of your body back to your liver. Your liver then removes the cholesterol from your body. LDL stands for low-density lipoproteins. It is sometimes called the "bad" cholesterol because a high LDL level leads to a buildup of cholesterol in your arteries. How do I know what my HDL level is? A blood test can measure your cholesterol levels, including HDL. When and how often you should get this test depends on your age, risk factors, and family history. The general recommendations are: For people who are age 19 or younger: The first test should be between ages 9 to 11 Children should have the test again every 5 years Some children may have this test starting at age 2 if there is a family history of high blood cholesterol, heart attack, or stroke For people who are age 20 or older: Younger adults should have the test every 5 years Men ages 45 to 65 and women ages 55 to 65 should have it every 1 to 2 years What should my HDL level be? With HDL cholesterol, higher numbers are better, because a high HDL level can lower your risk for coronary artery disease and stroke . How high your HDL should be depends on your age and sex: Group Healthy HDL Level Age 19 or younger More than 45mg/dl Men age 20 or older More than 40mg/dl Women age 20 or older More than 50mg/dl How can I raise
