Which of the following symptoms is NOT typically associated with hyperthyroidism?

Weight gain is indeed not typically associated with hyperthyroidism. In fact, hyperthyroidism is characterized by an overproduction of thyroid hormones, which accelerates the body's metabolism. As a result, individuals with hyperthyroidism usually experience weight loss rather than weight gain, despite having an increased appetite.

On the other hand, increased sweating, anxiety and irritability, along with palpitations, are common symptoms of hyperthyroidism. The elevated metabolic rate can lead to heat intolerance and excessive perspiration, while heightened levels of thyroid hormones can contribute to anxiety and mood disturbances. Palpitations occur due to the increased heart rate and cardiac output associated with elevated thyroid hormone levels. Understanding the typical presentations associated with hyperthyroidism is crucial for accurate clinical assessment and management.
