Low-density lipoprotein (LDL) or bad cholesterol- carries cholesterol to the arteries, if it is high, it can build up on the walls of the arteries which can narrow our arteries, limit blood flow, and raise the risk of blood clots. If a blood clot blocks an artery in the heart or brain, it can cause a heart attack or stroke.
High-density lipoprotein (HDL) or good cholesterol- It picks up excess LDL cholesterol to the liver to be removed from your body. It helps lower our risk of blood clots, heart disease, and stroke.
