What Is Cholesterol? Understanding LDL, HDL, and Heart Health

Cholesterol is a waxy, fat-like substance found in every cell of the body. It is needed to produce hormones, vitamin D, and substances that help digest food. Problems arise when cholesterol levels become imbalanced over time.

Low-density lipoprotein (LDL) is often called “bad cholesterol” because elevated levels can build up inside arteries. High-density lipoprotein (HDL), or “good cholesterol,” helps remove excess cholesterol from the bloodstream (1^✔ ✔Trusted Source
