Cholesterol Overview

Do you have high cholesterol, also known as hypercholesterolemia? Abnormal cholesterol levels such as high LDL cholesterol or low HDL cholesterol are a major risk factor for heart disease and stroke. An unhealthy diet can cause high cholesterol. Sometimes high cholesterol runs in families. A low-cholesterol diet can help improve cholesterol levels. If the low-cholesterol diet does not work to lower bad cholesterol and increase good cholesterol, your doctor may prescribe medications.

High Cholesterol: Diseases Linked to High Cholesterol

High cholesterol increases the risk of other conditions, depending on which blood vessels are narrowed or blocked. These diseases include: coronary heart disease, stroke and peripheral vascular disease. High cholesterol has also been linked to diabetes and high blood pressure. To prevent or manage these conditions, take steps to lower your cholesterol if it is elevated.

Coronary Heart Disease

The main risk associated with high cholesterol is coronary heart disease (CHD). Your blood cholesterol level has a lot to do with your chances of getting heart disease. If cholesterol is too high, it builds up in the walls of your arteries. Over time, this buildup (called plaque) causes hardening of the arteries (atherosclerosis). Atherosclerosis causes arteries to become narrowed, slowing blood flow to the heart. Reduced blood flow to the heart can result in angina (chest pain) or in a heart attack in cases when a blood vessel is blocked completely.
