Triglyceride levels are defined as follows:

  • normal is less than 150 mg/dL
  • 150-199 mg/dL is borderline high
  • 200-499 mg/dL indicates high triglycerides

  • cigarette smoking
  • diabetes
  • a diet in which more than 60% of the energy intake is from carbohydrates
  • hypothyroidism, or an underactive thyroid gland
  • inflammation of the pancreas, which in turn may be caused by high levels of triglycerides
  • an inherited, impaired ability to process fats that results in high levels of fats in the blood
  • lack of physical activity
  • overweight or obesity
