High Triglycerides


Overview

What are triglycerides?

Triglycerides are a type of fat found in your blood. Your body uses them for energy.

You need some triglycerides for good health. But high triglycerides might raise your risk of heart disease and may be a sign of metabolic syndrome.

Metabolic syndrome is the combination of high blood pressure, high blood sugar, too much fat around the waist, low HDL ("good") cholesterol, and high triglycerides. Metabolic syndrome increases your risk for heart disease, diabetes, and stroke.

A blood test that measures your cholesterol also measures your triglycerides. For a general idea about your triglycerides level, compare your test results to the following:1

  • Normal is less than 150.
  • Borderline-high is 150 to 199.
  • High is 200 to 499.
  • Very high is 500 or higher.

What causes high triglycerides?

High triglycerides are usually caused by other conditions, such as:

  • Obesity.
  • Poorly controlled diabetes.
  • An underactive thyroid (hypothyroidism).
  • Kidney disease.
  • Regularly eating more calories than you burn.
  • Drinking a lot of alcohol.

Certain medicines may also raise triglycerides. These medicines include:

In a few cases, high triglycerides also can run in families.

What are the symptoms?

High triglycerides usually don't cause symptoms.

But if your high triglycerides are caused by a genetic condition, you may see fatty deposits under your skin. These are called xanthomas (say "zan-THOH-muhs").

How can you lower your high triglycerides?

You can make diet and lifestyle changes to help lower your levels.

  • Lose weight and stay at a healthy weight.
  • Limit fats and sugars in your diet.
  • Be more active.
  • Quit smoking.
  • Limit alcohol.

You also may need medicine to help lower your triglycerides. But your doctor likely will ask you to try diet and lifestyle changes first.
