Which symptom is NOT typically associated with hyperthyroidism due to thyroid replacement?

• A. Weight gain
• B. Weight loss
• C. Heat intolerance
• D. Palpitations

Answer: (A)

Excess thyroid hormone speeds up the body's metabolism, which drives calories burn and heat production. That tends to cause weight loss, heat intolerance, and palpitations. In the context of thyroid replacement, taking too much hormone can create a hyperthyroid state with these symptoms. Weight gain, on the other hand, is not typical of hyperthyroidism from replacement; it would suggest under-replacement or another cause of weight gain. So the symptom that does not fit hyperthyroidism from replacement is weight gain.
