Cholesterol is a soft, fat-like, waxy substance found in the bloodstream and in all your body’s cells. It’s normal to have cholesterol. Cholesterol is an important part of a healthy body because it’s used for producing cell membranes and some hormones, and serves other needed bodily functions. But too much cholesterol in the blood is a major risk for coronary heart disease (which leads to heart attack) and for stroke. Hypercholesterolemia is the medical term for high levels of blood cholesterol.
Cholesterol comes from two sources: your body and food. Your liver and other cells in your body make about 75 percent of blood cholesterol. The other 25 percent comes from the foods you eat.
LDL cholesterol is the “bad” cholesterol. When too much of it circulates in the blood, it can clog arteries, increasing your risk of heart attack and stroke.
LDL cholesterol is produced naturally by the body, but many people inherit genes from their mother, father or even grandparents that cause them to make too much. Eating saturated fat, trans fats and dietary cholesterol also increases how much you have. If high blood cholesterol runs in your family, lifestyle modifications may not be enough to help lower your LDL blood cholesterol. Everyone is different, so work with your doctor to find a treatment plan that’s best for you.
Too much cholesterol in the blood can lead to cardiovascular disease — America’s No. 1 killer. The good news is, you can lower your cholesterol and reduce your risk of heart disease and stroke. Take responsibility for managing your cholesterol levels. Whether you’ve been prescribed medication or advised to make diet and lifestyle changes to help manage your cholesterol, carefully follow your doctor’s recommendations.
Your diet, weight, physical activity and exposure to tobacco smoke all affect your cholesterol level
For some people, lifestyle changes alone aren’t enough to reach healthy cholesterol levels. Your doctor may prescribe medication.
