HDL cholesterol

HDL cholesterol is a type of cholesterol that is often referred to as "good cholesterol". It is one of the two main types of cholesterol, the other being LDL cholesterol. HDL stands for high-density lipoprotein, which is the type of protein that carries cholesterol in the blood.

Overview

HDL cholesterol is considered "good" because it helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL cholesterol are associated with a lower risk of heart disease.

Function

HDL cholesterol is produced by the liver and is then released into the bloodstream. It travels through the bloodstream, picking up excess cholesterol and carrying it back to the liver. The liver then processes the cholesterol for excretion from the body.

Health Implications

Having high levels of HDL cholesterol can help reduce the risk of heart disease and stroke. This is because HDL cholesterol helps prevent the buildup of plaque in the arteries, a condition known as atherosclerosis.

However, low levels of HDL cholesterol can increase the risk of heart disease and stroke. This is because without enough HDL cholesterol to remove excess cholesterol from the bloodstream, there is a higher chance of plaque buildup in the arteries.

Measurement

HDL cholesterol levels are usually measured as part of a lipid panel, a type of blood test. The test measures total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.

Treatment

If a person's HDL cholesterol levels are too low, they may be advised to make lifestyle changes such as eating a healthier diet, exercising more, quitting smoking, and reducing alcohol intake. In some cases, medication may also be prescribed.
