Understanding Cholesterol: What You Need to Know About Your Levels

Cholesterol is a waxy substance found in the cells of your body and in your blood. While your body needs some cholesterol to function properly, having too much can lead to health problems. Understanding your cholesterol levels and how to manage them is crucial to maintaining good heart health.

Cholesterol is carried through your bloodstream by lipoproteins. There are two main types of lipoproteins that carry cholesterol: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL cholesterol is often referred to as “bad” cholesterol because it can build up in the walls of your arteries and form plaque, which can lead to heart disease. HDL cholesterol, on the other hand, is known as “good” cholesterol because it helps remove LDL cholesterol from your arteries.

When you get your cholesterol levels checked, your doctor will look at three key numbers:

1. Total cholesterol: This is a measure of all the cholesterol in your blood, including LDL and HDL cholesterol.

2. LDL cholesterol: This is the “bad” cholesterol that can build up in your arteries.

3. HDL cholesterol: This is the “good” cholesterol that helps remove LDL cholesterol from your arteries.

In general, a healthy total cholesterol level is less than 200 milligrams per deciliter (mg/dL), with LDL cholesterol levels less than 100 mg/dL and HDL cholesterol levels greater than 40 mg/dL for men and greater than 50 mg/dL for women.

There are several factors that can affect your cholesterol levels, including genetics, diet, exercise, and overall health. If you have high cholesterol, your doctor may recommend lifestyle changes such as following a heart-healthy diet, getting regular exercise, quitting smoking, and losing weight. In some cases, medication may be necessary to help lower your cholesterol levels.

Here are some frequently asked questions about cholesterol:
