Which of the following is NOT a classic symptom of hyperthyroidism?

1. Exophthalmos

2. Pretibial myxedema

3. Weight gain

4. Hyperthyroidism

The correct answer is: Weight gain

Weight gain is not a classic symptom of hyperthyroidism. In fact, hyperthyroidism typically presents with weight loss due to the accelerated metabolism that occurs when thyroid hormone levels are elevated. Patients often experience symptoms such as increased appetite but paradoxically lose weight as their bodies use energy more rapidly than usual. Exophthalmos, or bulging eyes, is a common symptom associated particularly with Graves' disease, an autoimmune form of hyperthyroidism. Pretibial myxedema, which manifests as a thickening and swelling of the skin on the shins, is also characteristic of Graves' disease. These symptoms reflect the effects of excess thyroid hormones on various systems in the body, contributing to the overarching clinical picture of hyperthyroidism. Therefore, weight gain is contrary to the expected symptoms, reinforcing that it does not fit within the classic presentation of this condition.
