How do hyperthyroidism and insulin requirements interact in diabetes management?

• A. Hyperthyroidism increases insulin clearance and may raise insulin requirements; hypothyroidism can alter insulin sensitivity with variable effects.
• B. Hyperthyroidism decreases insulin clearance and lowers insulin requirements.
• C. Hyperthyroidism has no effect on insulin metabolism.
• D. Hyperthyroidism cures diabetes.

Answer: (A)

When thyroid hormone levels are high, metabolism speeds up in many tissues, including the liver and kidneys. This acceleration increases how quickly insulin is cleared from the bloodstream and raises hepatic glucose production, so people with diabetes who develop hyperthyroidism often need more insulin to keep blood glucose in range. Treating the hyperthyroidism can reduce those insulin needs, sometimes returning them toward baseline. In contrast, hypothyroidism slows metabolism and can change how insulin works in a less predictable way. Insulin sensitivity and clearance can shift, so insulin requirements may go up or down depending on other factors like weight, lipid status, and the overall insulin action in that individual. Options suggesting that hyperthyroidism decreases insulin clearance or that there’s no effect are inconsistent with the way thyroid hormones modulate insulin metabolism. The idea that hyperthyroidism cures diabetes is clearly incorrect.
