A common metabolic feature often seen with PCOS due to insulin resistance is?

• A. Hyperthyroidism
• B. Metabolic syndrome
• C. Addison disease
• D. Cushing syndrome

Answer: (B)

Insulin resistance is central to PCOS and drives a cluster of metabolic abnormalities. When the body becomes resistant to insulin, the pancreas produces more insulin (hyperinsulinemia), which is associated with features that together define metabolic syndrome: central (abdominal) obesity, high triglycerides, low HDL cholesterol, high blood pressure, and elevated fasting glucose or impaired glucose tolerance. This collection of metabolic abnormalities is the most typical metabolic feature seen with PCOS linked to insulin resistance, making metabolic syndrome the best fit. Hyperthyroidism, Addison disease, and Cushing syndrome involve distinct hormonal issues. Hyperthyroidism changes overall metabolism in a way not specifically tied to PCOS-related insulin resistance. Addison disease is adrenal insufficiency with different metabolic effects, and Cushing syndrome stems from excess cortisol; while it can produce weight gain and glucose intolerance, the hallmark link to PCOS is through insulin resistance and the resultant metabolic syndrome cluster, not these other conditions.
