What are high triglycerides?
Triglycerides are a type of fat in your blood. Your body uses them for energy. You need some for good health. But high triglyceride levels are linked with a higher risk of coronary artery disease. A high level may be a sign of metabolic syndrome. Very high levels raise your risk of pancreatitis.
What causes this problem?
High triglycerides can run in families. They may also be caused by other conditions, like obesity and diabetes. You may have high levels of this fat if you eat or drink too many foods or drinks with added sugar or if you drink a lot of alcohol. And some medicines can cause this condition.
What are the symptoms?
High triglycerides usually don't cause symptoms. But if the condition is genetic, you may see fatty bumps under your skin.
How is this problem diagnosed?
A blood test is used to measure triglycerides. It's most accurate if it's done after you go without food or drink for 9 to 14 hours (fasting).
Triglyceride levels are:footnote 1
- Normal when they are less than 150 mg/dL.
- Moderately high when they are 150 to 499 mg/dL.
- Very high when they are 500 mg/dL or higher.
How are high triglycerides treated?
A healthy lifestyle can help lower your triglycerides and your risk of coronary artery disease. It includes losing weight, being active, limiting high-sugar foods and drinks, and limiting alcohol. Your doctor may recommend that you also take medicine. Your doctor will treat other health problems if they are causing high levels.
