Metabolic Syndrome

Condition

What is metabolic syndrome?

The term metabolic syndrome describes a cluster of risk factors that increase the chances of developing heart disease, stroke, and diabetes (high blood glucose, also called high blood sugar). The exact cause of metabolic syndrome is not known but genetic factors, too much body fat (especially in the waist area, the most dangerous type of fat), and lack of exercise add to the development of the condition. One in five Americans has metabolic syndrome.

You are diagnosed with metabolic syndrome if you have three or more risk factors:

  • Large amount of abdominal body fat: Waist measurement of more than 40 inches (102 cm) in men; more than 35 inches (88 cm) in women*
  • Low HDL (“good”) cholesterol: Less than 40 mg/dl in men; less than 50 mg/dl in women
  • High triglycerides (levels of fat in the blood): 150 mg/dl or higher
  • High blood pressure: 135/85 mmHg or higher, or use of blood pressure medications 
  • High blood glucose: Fasting glucose of 100 mg/dl or higher

*90-94 cm in men and 80 cm in women outside the United States.

Having three or more risk factors is a sign that the body is resistant to insulin, an important hormone produced by the pancreas. This resistance to insulin means that more insulin than normal is needed to keep the body working.

Who is at risk for metabolic syndrome?

The syndrome runs in families and is more common among African Americans, Hispanics, Asians, and Native Americans. For all people, the chances of developing the syndrome rises as people get older. You might be at risk for the syndrome if you don’t get much exercise and have:

Most people who have metabolic syndrome feel healthy and may not have any signs or symptoms, especially if they are not obese. However, they are at risk of developing life-threatening diseases like diabetes and heart disease in the future.

How is metabolic syndrome treated?

Increasing physical activity and losing weight are the best ways to begin to manage your condition. Medications can also be used to treat risk factors such as high blood pressure or high blood glucose (e.g., metformin) 

If you think you have risk factors for metabolic syndrome, talk with your doctor. Your doctor can run blood tests and measure your waist circumference to see if you have metabolic syndrome, and determine the best treatment option for you. Finding out if you have metabolic syndrome can give you a peek into your future health and see if you are headed down the path to heart disease. It will also give you time to make important lifestyle changes before serious complications develop.
