What is cholesterol?
Cholesterol is a waxy, fat-like substance that is naturally present in cell walls or membranes everywhere in the body. The body uses cholesterol to produce many hormones, vitamin D, and bile acids that help to digest fat. Too much cholesterol in your bloodstream can lead to narrowing of arteries in the body that cause heart attacks, strokes, and peripheral artery disease.

Cholesterol levels are checked by a simple blood test. This test measures total cholesterol, low-density lipoproteins (LDL) cholesterol, high-density lipoproteins (HDL) cholesterol, and triglycerides. Your health-care
professional will be able to help you interpret the blood test results to determine if your cholesterol levels are normal or require treatment.
