What are the different types of cholesterol?

Low-density lipoprotein (LDL), also known as "bad" cholesterol, is a type of cholesterol that can build up in the walls of your arteries, narrowing them and making it harder for blood to flow through them. This can lead to heart disease and stroke.

High-density lipoprotein (HDL), also known as "good" cholesterol, is a type of cholesterol that helps to remove LDL cholesterol from the arteries and transport it back to the liver, where it is broken down and removed from the body. HDL cholesterol is associated with a lower risk of heart disease and stroke.

Very low-density lipoprotein (VLDL) cholesterol is a type of cholesterol that is produced in the liver and carries triglycerides, a type of fat, to the cells in your body. VLDL cholesterol can also build up in the walls of your arteries and contribute to heart disease and stroke.

Triglycerides are a type of fat that is stored in your body's fat cells and can also be found in your blood. High levels of triglycerides can increase your risk of heart disease and stroke.

Total cholesterol is the total amount of LDL, HDL, and VLDL cholesterol in your blood. A high total cholesterol level can increase your risk of heart disease and stroke.
