A high triglyceride count in a person's blood is a symptom of diseases such as diabetes. The body needs insulin to remove excess triglycerides from the blood.

Having elevated amounts of triglycerides in your blood may also increase the risk of heart disease (a normal reading is less than 200 mg/dl). You can generally lower the amount of triglyceride in your blood by exercising, eating a low-fat diet, and losing weight.
