High cholesterol can lead to heart attack and stroke.
Buildup of cholesterol in the arteries is also known as atherosclerosis — sometimes called hardening of the arteries. When arteries are clogged, there is a greater risk of problems such as heart attack and stroke.
What is cholesterol?
Cholesterol is a waxy, fat-like substance that helps make vitamins and hormones in the body. It also travels in the bloodstream in small packages of lipoproteins (fat + protein).
Types of cholesterol.
“Good” cholesterol (HDL) is made up of high-density lipoproteins. “Bad” cholesterol (LDL) is made up of low-density lipoproteins. LDL can lead to cholesterol buildup and plaque in blood vessels, causing narrowing and hardening of the arteries, which triggers a condition called high blood cholesterol and increases the risk of coronary heart disease, heart attack, and stroke. Triglycerides are another form of fat found in the blood. Calories you eat that your body doesn’t need right away become triglycerides and are stored in your fat cells.
