Which statement best describes the metabolic dysfunction commonly associated with PCOS?

• A. Hyperthyroidism causing weight changes.
• B. Endocrine disorder that affects the thyroid and insulin regulation.
• C. Endocrine disorder with insulin resistance and hyperandrogenism leading to metabolic dysfunction.
• D. A deficiency of cortisol production.

Answer: (C)

PCOS is an endocrine condition where insulin resistance and elevated androgens drive the metabolic problems. Insulin resistance means higher circulating insulin, which stimulates the ovaries to produce more androgens and lowers the levels of sex hormone–binding globulin, increasing free testosterone. That combination leads to metabolic dysfunction such as impaired glucose tolerance, dyslipidemia, and weight gain, and it underlies the characteristic symptoms like irregular ovulation and hirsutism. Hyperthyroidism or thyroid-related issues aren’t the defining feature of PCOS, so describing it as a thyroid and insulin regulation problem isn’t accurate. Cortisol deficiency points to adrenal insufficiency, which has a different clinical picture altogether.
