Causes

Causes may include:

Risk Factors

These factors increase your chance of developing this condition. Tell your doctor if you have any of these:

Symptoms

Hyperlipidemia usually does not cause symptoms. Very high levels of lipids or triglycerides can cause:

  • Fat deposits in the skin or tendons (xanthomas)
  • Pain, enlargement, or swelling of organs such as the liver, spleen, or pancreas (pancreatitis)
  • Obstruction of blood vessels in heart and brain

Diagnosis

This condition is diagnosed with blood tests. These tests measure the levels of lipids in the blood. The National Cholesterol Education Program advises that you have your lipids checked at least once every five years, starting at age 20.

Testing may consist of a fasting blood test for:

  • Total cholesterol
  • LDL (bad cholesterol)
  • HDL (good cholesterol)
  • Triglycerides

Your doctor may recommend more frequent or earlier testing if you have:

  • Family history of hyperlipidemia
  • Risk factor or disease that may cause hyperlipidemia
  • Complication that may result from hyperlipidemia

Treatment

Diet, lifestyle changes, and medication can help treat hyperlipidemia.

Diet Changes

Lifestyle Changes

  • If you are overweight, lose weight.
  • If you smoke, quit.
  • Exercise regularly. Talk to you doctor before starting an exercise program. You may already have hardening of the arteries or heart disease. These conditions increase your risk of having a heart attack while exercising.

Medications

There are a number of drugs available, such as statins, to treat this condition. Talk to your doctor.

Prevention

To help reduce your chance of getting hyperlipidemia, take the following steps:

  • Starting at age 20, get cholesterol tests.
  • Eat a diet low in total fat, saturated fat, and cholesterol.
  • If you smoke, quit.
  • Drink alcohol in moderation (two drinks per day for men, one drink per day for women).
  • If you are overweight, lose weight.
  • Exercise regularly. Talk with your doctor first.
  • If you have diabetes, control your blood sugar.
  • Talk to your doctor about medications you are taking. They may have side effects that cause hyperlipidemia.
