Insulin Resistance

Background

Insulin resistance is a state in which a given concentration of insulin produces a less-than-expected biological effect. Insulin resistance has also been arbitrarily defined as the requirement of 200 or more units of insulin per day to attain glycemic control and to prevent ketosis.

The syndromes of insulin resistance actually make up a broad clinical spectrum, which includes obesity, glucose intolerance, diabetes, and the metabolic syndrome, as well as an extreme insulin-resistant state. Many of these disorders are associated with various endocrine, metabolic, and genetic conditions. These syndromes may also be associated with immunological diseases and may exhibit distinct phenotypic characteristics.

The metabolic syndrome —a state of insulin-resistance that is also known as either syndrome X or the dysmetabolic syndrome—has drawn the greatest attention because of its public health importance.

In an effort to clinically identify patients with insulin resistance, various organizations have developed diagnostic criteria. The most commonly used criteria in the United States are those of the National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATP III).

  • NCEP/ATP III criteria for the diagnosis of the metabolic syndrome include the following (diagnosis is made when 3 or more are present):
    • Waist circumference of more than 102 cm in men or more than 88 cm in women
    • Fasting triglyceride level of 150 mg/dL or higher
    • Blood pressure level of 130/85 mm Hg or higher
    • High-density lipoprotein cholesterol (HDL-C) level of less than 40 mg/dL in men or less than 50 mg/dL in women
    • Fasting glucose level of 110 mg/dL or higher (which has been changed to 100 mg/dL to reflect revised criteria for impaired fasting glucose [IFG])
