Triglycerides are a type of fat found in your blood. They are a major source of energy and the most common type of fat in your body.

When you eat, your body uses the calories it needs for quick energy. Any extra calories are turned into triglycerides and stored in fat cells to be used later.

Conditions that may cause high triglyceride levels include:
Poorly controlled diabetes
An underactive thyroid
Kidney disease
Regularly eating more calories than you burn
Drinking a lot of alcohol

High triglycerides usually do not cause symptoms. If you are overweight, losing weight may be the best way to lower triglycerides. Ask your pharmacist for advice on exercise and a healthy diet.
