Cholesterol is a waxy, fat-like substance made by the liver and found in certain foods. Your liver makes enough for your body’s needs, but we often get more cholesterol from the foods we eat. If we take in more cholesterol than the body can use, the extra cholesterol can build up in the arteries, including those of the brain. This can lead to narrowing of the arteries, stroke, and other problems.
A blood test can tell your doctor if you have high levels of cholesterol and triglycerides (a related kind of fat) in your blood.
