Which of the following is NOT a finding associated with Hyperthyroidism?

Weight gain is not a typical finding associated with hyperthyroidism. In fact, hyperthyroidism usually leads to weight loss despite increased appetite because of the heightened metabolic rate. Patients may experience symptoms such as heart palpitations due to increased cardiac output and increased heart rate, heat intolerance due to an elevated basal metabolic rate which causes excessive sweating, and hair loss as a result of hormonal changes affecting hair follicles. Each of these observed symptoms directly correlates with the physiological effects of excessive thyroid hormone production, which differs significantly from the weight gain that is commonly associated with conditions like hypothyroidism.
