    LDL: The 'Bad' Cholesterol

    If you have heart disease or you just want to keep your ticker healthy, you've probably heard the mantra already: "Watch your cholesterol!" The type that puts your heart at risk is LDL -- the "bad" cholesterol.

    It collects in the walls of your blood vessels, where it can cause blockages. Higher LDL levels put you at greater risk for a heart attack from a sudden blood clot that forms there.

    Get a simple blood test to check your LDL levels. If they're high, diet and medicine can help you lower it.

    What Is LDL?

    Cholesterol isn't all bad. It's an essential fat that the cells in your body need.

    Some cholesterol comes from the food you eat and some is made by your liver. It can't dissolve in blood, so proteins carry it where it needs to go. These carriers are called "lipoproteins."

    LDL is a microscopic blob that's made up of an outer rim of lipoprotein that surrounds a cholesterol center. Its full name is "low-density lipoprotein."

    What LDL Cholesterol Test Results Mean

    Although heart attacks are unpredictable, higher levels of LDL raise your risk of heart disease. Until recently, guidelines for cutting those odds put an emphasis on lowering this "bad" cholesterol to specific target numbers.

    Nowadays, you and your doctor work together to develop your own personal strategy to lower LDL by a certain percentage. It's based on your level of risk for heart disease or strokes. To figure it out, doctors use a calculator to estimate the chances you'll have those problems in the next 10 years.

    The calculator takes several things into account, including your cholesterol numbers, age, blood pressure, whether you smoke, or if you use blood pressure medicines. All of these things affect your odds of getting a heart problem. Other risks include diabetes or a family history of heart disease.

    Your doctor then sets up a plan of lifestyle changes or medication that can lower both your cholesterol and overall risk.

    What You Can Do

    A healthy diet and exercise can help cut your LDL levels. Eat foods that are low in saturated fat and dietary cholesterol. You can lower your numbers even more if you add fiber and plant sterols (like cholesterol-lowering margarine or nuts) to your diet.

    Congratulations! Your total cholesterol level is in the Desirable range, and your level of "bad" LDL cholesterol is optimal.

    Congratulations! Your total cholesterol level is in the Desirable range, and your level of "bad" LDL cholesterol is near optimal.

    Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is borderline high. If your LDL goes higher, your total cholesterol level could become Borderline High. Consider reducing the amount of foods you eat with saturated fats and increasing physical activity. If you get more exercise, your level of "good" HDL cholesterol may increase, which could also help to keep your levels of LDL and total cholesterol in check.

    Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is High. This may mean that your level of high-density lipoprotein (HDL), or "good" cholesterol, is too low. It is best to have a high level of "good" HDL and a low level of "bad" LDL. The HDL helps keep your LDL level in check. Ask your doctor for your HDL level. If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level.

    Your total cholesterol level is in the Desirable range, but your level of "bad" LDL cholesterol is Very High. This may mean that your level of high-density lipoprotein (HDL), or "good" cholesterol, is too low. It is best to have a high level of "good" HDL and a low level of "bad" LDL because the HDL helps keep your LDL level in check. Ask your doctor for your HDL level. If your HDL is low, increasing your physical activity can increase it, which may help reduce your LDL level.

    Your total cholesterol level is Borderline High, but fortunately your level of "bad" LDL cholesterol is optimal. This could mean you have a high level of high-density lipoprotein, or "good" HDL cholesterol, which protects against heart disease. Or you could have other non-measured increases in LDL-like particles that can increase heart disease. Your LDL level also could be optimal if you are taking a statin medication. Please check with your doctor to get your complete lipid profile and see if you may need additional treatment. In the meantime, find more information on WebMD's Cholesterol Health Center.
