Cholesterol and lipids

Cholesterol and lipids: Introduction

High cholesterol, also called hypercholesterolemia or hyperlipidemia, is a very common condition in which the level of total cholesterol in the blood is higher than normal. High cholesterol is a serious condition and increases the risk of developing such life-threatening diseases as heart disease, stroke, and heart attack.

Cholesterol is a naturally occurring waxy, fat-like substance that is present in the blood and in the body's cells. It is both made by the body itself and is also brought into the body through eating certain foods such as animal meats, which contains various levels of cholesterol.

Cholesterol is comprised primarily of three components, HDL (good cholesterol), LDL (bad cholesterol) and triglycerides. These components of cholesterol are a necessary element in the proper functioning of the body. When the HDL, LDL, and triglycerides are present in the right levels and balance in the body, cholesterol functions to protect health, including cardiovascular health.

However, when the total cholesterol levels become too high, and the levels and balance of HDL, LDL, and triglycerides in the body are not normal, it can result in the buildup of plaque on the walls of the arteries and increase the risk for developing cardiovascular diseases. These include atherosclerosis, heart disease, blood clots, hypertension, myocardial infarction and stroke. Heart disease is the number one killer of women and men in the United States, and more than a million Americans have myocardial infarctions, according to the National Heart, Lung, and Blood institute.

There generally are no symptoms of high cholesterol until complications develop. For more information on symptoms and complications, refer to symptoms of high cholesterol.

Making a diagnosis of high cholesterol includes completing a complete medical evaluation and history and physical examination. Diagnostic testing includes a blood test that measures cholesterol levels. Cholesterol testing primarily measures the total amount of cholesterol and the three components of cholesterol, HDL, LDL and triglycerides.

However, blood cholesterol levels are only one aspect that can help determine a person's total risk for developing cardiovascular disease. A comprehensive evaluation from a licensed health care professional includes compiling and analyzing many factors that impact cardiovascular disease risk. These include lifestyle, family history, personal history, dietary habits, weight, blood pressure, stress levels, and smoking/drinking habits. Other tests, including blood tests, EKG, and imaging tests, such as heart scans, are also evaluated to assess risk and if any complications of high cholesterol have developed.

It is very possible that a diagnosis of high cholesterol can be missed or delayed because there are generally no symptoms. For more information on misdiagnosis, refer to misdiagnosis of high cholesterol.

High cholesterol can be successfully treated with an individualized treatment plan that best fits the individual case of high cholesterol and a person's life style. Treatment generally involves regular medical monitoring and cholesterol testing and lifestyle and dietary changes. Treatment may also include medication for some people who are unable to normalize their cholesterol levels through diet and lifestyle changes.

Article Excerpts about Cholesterol and lipids

Cholesterol is a fatty substance produced by the liver to help meet the body’s need for hormones and bile acids. It also enters the body when high-fat foods are consumed and when the body’s cholesterol level is higher than necessary for normal cell functioning. The resulting high blood cholesterol is a condition that greatly increases your chances of developing coronary heart disease. That is because extra cholesterol in the blood settles on the inner walls of the arteries, narrowing them, allowing less blood to pass through them to the heart. The higher your total blood cholesterol level, the greater your heart disease risk. (Source: excerpt from High Blood Cholesterol: NWHIC)
