My doctor said I have high cholesterol. What are the different types of cholesterol and what can I do to lower it?

The three main types of cholesterol are HDL, LDL, and triglycerides. High-density lipoprotein (HDL) is often referred to as “good” cholesterol because it helps remove excess cholesterol from your body. Low-density lipoprotein (LDL) is sometimes referred to as “bad” cholesterol because it increases your risk for heart disease. Triglycerides are another type of fat that circulates in the bloodstream.
