Overview
Cholesterol is a waxy, fat-like substance found in all cells. It is needed to build cells and hormones, but high levels of certain types can increase the risk of heart disease. This guide covers the different types of cholesterol and how to manage them.
Types of Cholesterol
LDL (low-density lipoprotein) is the 'bad' cholesterol that can build up in arteries. HDL (high-density lipoprotein) is the 'good' cholesterol that helps remove LDL. Triglycerides are another type of fat in the blood.
Normal Levels
Desirable levels are: Total cholesterol under 200 mg/dL, LDL under 100 mg/dL, HDL 60 mg/dL or higher, and triglycerides under 150 mg/dL.
Management
Managing cholesterol involves lifestyle changes: a heart-healthy diet (low in saturated fat), regular exercise, maintaining a healthy weight, and medications (statins) if needed.
When to See a Doctor
Adults should get their cholesterol checked every 4-6 years. Those with risk factors may need more frequent testing.
