Too much cholesterol can block the coronary arteries completely, cutting off the blood and oxygen that the heart needs to function. This situation could eventually cause a heart attack. High blood cholesterol has been identified as one factor that increases the risk of coronary heart disease. The good news is that decreasing these risk factors can reduce cholesterol deposits in arteries. Although a small percentage of people have diseases or inherited abnormalities that result in elevated LDL cholesterol levels, most people bring it on through lifestyle habits.
Treatment includes dietary changes, regular exercise, weight control, and sometimes drug therapy.
When your doctor recommends a cholesterol test, the first results will probably be a measurement of total cholesterol. This number is a good indication of whether you will need to modify your lifestyle. This test is often repeated several weeks later, and an average is obtained to give a more accurate picture. You will probably be advised to maintain a prudent diet and repeat your cholesterol measurement in five years. You should consult your doctor to confirm results and for advice on diet and other activities.
