Both the definition and the cause of metabolic syndrome are still controversial, however. Metabolic syndrome is a group of risk factors for heart disease and diabetes that includes high blood pressure, high blood sugar, high levels of triglycerides, low levels of HDL, and excess weight, especially abdominal fat. The cause may be insulin resistance -- when cells ignore the effects of insulin.
Type 2 diabetes is high blood sugar that results when cells become resistant to insulin, the hormone needed to allow glucose from the bloodstream to enter cells. The pancreas may also slow down production of insulin in type 2 diabetes.
