What Is the Difference Between HDL & LDL?

HDL (high-density lipoprotein) and LDL (low-density lipoprotein) are types of cholesterol. A lipoprotein is a substance that is part lipid or fat and part protein. HDLs are generally considered to be good for the body, while LDLs are considered bad.

Sources

• The body produces cholesterol, both HDL and LDL. HDL is acquired by eating fish or olive oil, while LDL is acquired from processed foods, eggs and poultry.

LDL Effects

• LDL can build up along the arterial walls contributing to plaques that block blood flow and cause the arteries to thicken. This is a condition called atherosclerosis and can lead to heart attacks.

HDL Effects

• The body uses HDL for the repair of tissues and cells. The American Heart Association reports it is believed HDL reduces the amount of LDL.

Levels

• Proper diet and exercise will help to lower the levels of LDL while increasing the levels of HDL. Total cholesterol levels for both types should come in less than 200 milligrams per deciliter.

Tests and Medication

• High cholesterol frequently lacks symptoms, so a cholesterol test is the only way to determine cholesterol levels. High cholesterol is often treated with statin drugs, which help to reduce LDL levels.
