Take the Cholesterol Quiz
Cholesterol is a soft, waxy substance found in all parts of your body. It helps form cell membranes and helps your body make some hormones and vitamin D. Excess cholesterol can build up in the arteries, narrowing them and slowing or blocking blood flow to the heart, brain, and other organs.
