There are many factors that affect your blood cholesterol levels, including factors that can be controlled by lifestyle choices, such as your diet, your physical activity, and your weight.
It is important to control your cholesterol because high levels of blood cholesterol are a risk factor for heart disease and stroke — the major causes of death in the United States.
New guidelines in the May 16, 2001, issue of the Journal of the American Medical Association give recommendations for lowering your risk of heart disease and stroke by lowering the levels of cholesterol in the blood.
Cholesterol and Blood Lipids (Fats)
Cholesterol is a substance that plays an important role in many of the body's functions. Cholesterol that is not being used by the body builds up in the bloodstream. Having too much cholesterol in your blood puts you at risk of heart disease, including a heart attack.
Low-density lipoprotein (LDL) is made up of lipid (fat) and protein. LDL carries cholesterol to the body's tissues. LDL cholesterol is sometimes referred to as "bad cholesterol" because it is the source of cholesterol buildup in the walls of the arteries.
Triglycerides are a form of fat that is found in the blood and in foods. Excess levels of triglycerides in the blood can also increase your risk of heart disease.
Tips for Improving Your Blood Cholesterol Level
· Eat a diet low in saturated fats and cholesterol.
· Increase your physical activity. Talk to your doctor before making any major increases in your physical activity.
· Lose weight if you are overweight.
Even if you are taking the above measures, you should continue to have your cholesterol levels checked. If your cholesterol levels are still high, your doctor may prescribe cholesterol-lowering medication.
What Is Atherosclerosis?
Atherosclerosis is narrowing of the arteries caused by cholesterol and fatty deposits in the walls of the arteries. This narrowing can affect the arteries of the heart — the coronary arteries. When there is a complete blockage of the blood flow to the heart, death of part of the heart muscle may occur. This is known as myocardial infarction, or "heart attack." Atherosclerosis also can increase your risk of experiencing a stroke.
