Cholesterol and triglyceride test
Toggle: English / Spanish
Maybe you've been eating fast food more often than you should, or you're not getting your recommended two-and-a-half hours of exercise each week. Or, it could be that you smoke, or your blood pressure is too high. Well, for whatever reason, you may be concerned about your risk of getting heart disease.
Well, a few tests can help you learn that risk, so you can start making healthy lifestyle changes to reduce it. A coronary risk profile is a group of blood tests that measure your cholesterol and triglyceride levels. Why is it important to know these levels? Because if you have too much of these substances in your blood from eating foods like burgers and French fries, they can clog your arteries. Eventually your arteries can become so clogged that you'll have a heart attack or stroke.
Men should have their cholesterol tested by the time they're 35. Women should have it checked by age 45. If you have a condition like diabetes, heart disease, stroke, or high blood pressure, have your cholesterol checked now, no matter what your age.
To measure your cholesterol, your doctor will give you a blood test. If you're also having your triglyceride level checked, you may be told not to eat or drink anything for 8 to 12 hours before the test. Depending upon your heart risk, the doctor may measure just your total cholesterol level, or your total cholesterol along with your LDL, or "bad" cholesterol, HDL, or "good" cholesterol, and triglycerides. If you're of average risk of getting heart disease, your goal is to have total cholesterol of less than 200 milligrams per deciliter, LDL cholesterol lower than 130 milligrams per deciliter, HDL cholesterol higher than 40 milligrams per deciliter if you're a man, or 50 if you're a woman -- the higher the better, and triglycerides of less than 150 also, the lower the better.
Although some illnesses, like arthritis, can raise your cholesterol level, generally having high cholesterol means that you're at increased risk for heart disease and stroke. It's a sign you need to work harder to keep your heart healthy. If your cholesterol levels are normal, that's great! That means that you're eating right, you're exercising, and you're taking good care of your health. You don't need to have another cholesterol test for about five years. But if your cholesterol level is high, or you've already got heart disease, high blood pressure, or diabetes, you'll need to have your cholesterol levels checked more often.
Keeping close tabs on your cholesterol and triglyceride levels is one way that you can take charge of your health, and change it for the better.
