What symptom is NOT commonly associated with hyperthyroidism?

Fatigue is often associated with hyperthyroidism, but it is typically more characteristic of hypothyroidism, where individuals experience low energy and tiredness due to decreased metabolic activity. Hyperthyroidism, on the other hand, tends to speed up the body's metabolism, leading to a range of symptoms that reflect this increased activity.

In hyperthyroidism, symptoms such as weight loss, increased heart rate, and heat intolerance are common as the body is in a heightened state of metabolic function. People may often experience increased energy levels and heightened physical activity, which contrasts with the fatigue seen in hypothyroidism. Therefore, identifying fatigue as a symptom of hyperthyroidism is less accurate compared to the other symptoms that align more closely with the condition's physiological effects.
