Cholesterol is a waxy, fat-like substance that’s found in all cells of the body. Cholesterol travels through your bloodstream in small packages called lipoproteins. These packages are made of fat (lipid) on the inside and proteins on the outside.
Two kinds of lipoproteins carry cholesterol throughout your body:
Low-density lipoproteins (LDL)
High-density lipoproteins (HDL).
Sometimes is called “bad” cholesterol. A high LDL level leads to a buildup of cholesterol in your arteries. (Arteries are blood vessels that carry blood from your heart to your body.)
Sometimes is called “good” cholesterol. This is because it carries cholesterol from other parts of your body back to your liver. Your liver removes the cholesterol from your body.
What Is High Blood Cholesterol?
High blood cholesterol is a condition in which you have too much cholesterol in your blood. The higher the level of LDL cholesterol in your blood, the greater your chance is of getting heart disease. The higher the level of HDL cholesterol in your blood, the lower your chance is of getting heart disease.
