Information on HDL

Cholesterol, which helps produce certain hormones and cell membranes, is a fatty, waxy substance found in the bloodstream. To travel through the bloodstream, it must attach itself to a protein. The two types of protein that cholesterol can attach itself to are low-density lipoprotein (LDL) and high-density lipoprotein (HDL).

Definition

• HDL, which is known as "good" cholesterol, is a structure made of both protein and lipid, or cholesterol. It is one of the smallest lipoprotein particles in the bloodstream, but it contains the highest protein density among all lipoproteins.

Function

• HDL binds to excess cholesterol in the body and carries it to the liver, where it can be expelled.

Diagnosis

• A doctor can check HDL levels by ordering a cholesterol test. A blood sample is taken to measure your total cholesterol count.

Benefits

• According to the Mayo Clinic, increased HDL levels can reduce your risk of heart disease. High HDL levels may also have anti-inflammatory and anti-clotting effects on the cardiovascular system.

Raising HDL Levels

• Exercising, stopping tobacco use and maintaining a healthy weight promote higher HDL levels. Excessive alcohol consumption should also be avoided.
