LDL Cholesterol

By Medically reviewed by hellodoktor


What is LDL-Cholesterol?

Cholesterol is a waxy substance that’s found in the fats (lipids) in your blood. While cholesterol is crucial for the formation of cell membranes, vitamin D, digestive bile acids, and certain hormones, having high cholesterol can increase your risk of heart disease.

Cholesterol can’t dissolve in the blood. It must be transported through your bloodstream by carriers called lipoproteins. There are two types of cholesterol, based on what type of cholesterol the lipoprotein carries:

  • Low-density lipoprotein (LDL) is referred as a bad cholesterol that LDL cholesterol builds up in the walls of your arteries, making them hard and narrow.
  • High-density lipoprotein (HDL) is considered as a good cholesterol because it helps remove the excess LDL cholesterol from the arteries and takes it back to your liver.

The higher level of LDL cholesterol you have in your arteries, the greater risk for a heart attack from a sudden blood clot you might experience. High cholesterol is associated with an elevated risk of cardiovascular disease. That can include coronary heart disease, stroke, and peripheral vascular disease. High cholesterol linked to diabetes and high blood pressure.
