Cholesterol |
|
|
There are actually different kinds of blood cholesterol that make up your total cholesterol numbers. The two types that are measured are high-density lipoprotein, or HDL, and low-density lipoprotein, or LDL. These lipoproteins coat the cholesterol in our body so it can travel through the blood. LDL is sometimes called the “bad” cholesterol, because it causes cholesterol to build up in the walls of the arteries. This buildup can eventually clog the arteries and reduce the blood supply to the heart. So the more LDL you have in your blood, the greater your risk for heart disease. HDL can be considered the “good” cholesterol because it helps your body get rid of the cholesterol in your blood. The higher the number, the better. Your report may also read out your triglyceride level. Its not entirely clear whether high triglycerides alone increase your risk of heart disease, but many people with high LDL or low HDL also have high triglycerides. Ideally, total cholesterol should be less than 200. Depending on other risk factors for heart disease, any result higher than 200 requires specific attention. In people without heart disease, a desirable level for LDL is less than 130 and for HDL, more than 35. A low-fat high fiber diet, including whole grain cereals and soy can help most people reduce their cholesterol levels. Exercise can both lower LDL and raise HDL. But if diet is not enough, your doctor may recommend a cholesterol-lowering medicine. |

At what age should we get our cholesterol levels checked? In general, men at age 40 and women at age 45. Anyone with risk factors for heart disease or high cholesterol may be advised by their doctor to have earlier screening. | |
