A triglycerides test measures the amount of triglycerides in your blood. Triglycerides are a

type of fat in your body. If you eat more calories than you need, the extra calories are

changed into triglycerides. These triglycerides are stored in your fat cells for later use. When

your body needs energy, triglycerides are released into your bloodstream to provide fuel for

your muscles to work. If you eat more calories than you burn off, especially calories from

carbohydrates and fats, you may get high triglyceride levels in your blood. High triglycerides

may put you at greater risk for a heart attack or stroke.
