Which symptom is NOT typically associated with hyperthyroidism?

Weight gain is not typically associated with hyperthyroidism; in fact, hyperthyroidism usually leads to weight loss due to an accelerated metabolism. Individuals with this condition often experience symptoms such as an increased appetite, hair loss, and thinning skin, all of which stem from the heightened metabolic state caused by excess thyroid hormone.

In hyperthyroidism, the body's metabolism works faster than normal, which triggers the weight loss and increased appetite. Hair loss and thinning of the skin can be explained by the hormonal imbalances affecting various bodily functions, including those related to hair follicle health and skin regeneration. Thus, weight gain stands out as it contradicts the expected physiological responses seen in hyperthyroidism.
