Ask The Expert: What is Cholesterol?

Cholesterol is a waxy, fat-like substance that is found in all cells of the body. It is essential for many bodily functions, such as hormone production, cell growth, and digestion. However, high levels of cholesterol can lead to serious health problems, such as heart disease and stroke.

There are two types of cholesterol: LDL (low-density lipoprotein) and HDL (high-density lipoprotein). LDL cholesterol is often referred to as "bad" cholesterol because it can build up in the arteries and cause them to narrow. This can lead to heart disease and stroke. HDL cholesterol is often referred to as "good" cholesterol because it helps to remove LDL cholesterol from the arteries and protect against heart disease.

Cholesterol levels are determined by a number of factors, including genetics, diet, and lifestyle. Some people are more likely to have high cholesterol than others. However, everyone can take steps to lower their cholesterol levels, such as eating a healthy diet, getting regular exercise, and quitting smoking.

If you have high cholesterol, your doctor may prescribe medication to help lower your levels. There are a number of different types of cholesterol medications, and your doctor will choose the best one for you based on your individual needs.

Cholesterol is an important substance for the body, but high levels can lead to serious health problems. By following a healthy lifestyle and taking medication if necessary, you can help to lower your cholesterol levels and reduce your risk of heart disease and stroke.
