Category Triglyceride Level in milligrams per deciliter (mg/dL) What It Means for You Normal Less than 150 You can reduce your risk for future problems with a healthy lifestyle, which includes maintaining a healthy weight, getting regular physical activity, limiting alcohol, not smoking, and eating a healthy diet. Borderline High 150 to 199 This level is typically due to lifestyle factors. It's generally treated with lifestyle changes. If other diseases (such as diabetes, kidney disease, or an underactive thyroid) or medications (such as beta blockers or corticosteroids) are contributing to the problem, they should be addressed, too. High 200 to 499 This level is typically caused by a combination of lifestyle and genetic factors. Many people with high triglycerides also have other risk factors for heart disease, such as a large waistline and insulin resistance, which may lead to diabetes. Lifestyle change is the first-choice treatment. Medications are also sometimes prescribed. Very High 500 and up This level is typically caused by a combination of lifestyle and genetic factors. People with very high triglycerides often have type 2 diabetes and other risk factors for heart disease. When triglyceride levels exceed 1,000 mg/dl, there is an increased risk for acute pancreatitis (inflammation of the pancreas). A very high triglyceride level is generally treated with a combination of lifestyle changes and medication.
