HDL (high-density lipoprotein), or the "good" cholesterol, and LDL (low-density lipoprotein), or the "bad" cholesterol, are lipoproteins that carry cholesterol through the veins and arteries of the body. HDL and LDL combined, is your "total" blood cholesterol. The difference between the two are that high levels of the "good," or HDL cholesterol, may protect against narrowing of the blood vessels in the body, which protects you against heart attack, stroke, and other cardiovascular diseases. But high levels of LDL, or the "bad" cholesterol, may worsen the narrowing of the blood vessels in the body, which puts you at a greater risk of stroke, heart attack, and cardiovascular diseases, some of which are life threatening.
