How is Metabolic Syndrome Diagnosed?

There are no well-accepted criteria for diagnosing the metabolic syndrome. The criteria proposed by the National Cholesterol Education Program(NCEP) Adult Treatment Panel III(ATP III), with minor modifications, are currently recommended and widely used.

The American Heart Association and the Nation Heart, Lung, and Blood Institute recommend that the metabolic syndrome be identified as the presence of three or more of these components:

  • Elevated waist circumference:

Men - Equal to or greater than 40 inches (102 cm) Women - Equal to or greater than 35 inches (88 cm)

  • Elevated triglycerides:

Equal to or greater than 150 mg/dL

  • Reduced HDL ("good") cholesterol:

Men - Less than 40 mg/dL Women - Less than 50 mg/dL

  • Elevated blood pressure:

Equal to or greater than 130/85 mm Hg

  • Elevated fasting glucose level

Equal to or greater than 100 mg/dL
