Which symptom is NOT typical of hyperthyroidism?

Hyperthyroidism is characterized by an overproduction of thyroid hormones, leading to a range of symptoms associated with an increased metabolic rate. Muscle weakness and exophthalmos, which is the protrusion of the eyes, are common symptoms experienced by individuals with this condition.

In hyperthyroidism, gastrointestinal symptoms typically include increased bowel movements or diarrhea due to the accelerated metabolism, which contrasts with constipation. This makes constipation atypical for hyperthyroidism, as patients are more likely to experience frequent or loose stools rather than difficulty with bowel movements. Therefore, the presence of constipation does not align with the symptomatology typically observed in hyperthyroidism, supporting the identification of this symptom as the one that is not characteristic of the condition.
