Which of the following is NOT a symptom of hyperthyroidism?

Cold intolerance is not a symptom of hyperthyroidism. In fact, hyperthyroidism generally leads to heat intolerance as the overproduction of thyroid hormones results in an increased metabolism, causing the body to generate more heat. This increased metabolism also typically manifests in symptoms such as weight loss, an increased heart rate, and heightened appetite, all of which are characteristic of hyperthyroidism.

In patients experiencing hyperthyroidism, the body's heightened metabolic function displaces heat regulation, leading them to feel warm, even in cooler environments, making cold intolerance an incorrect symptom associated with this condition.
