What is a typical symptom of Graves' disease?

Graves' disease is an autoimmune hyperthyroid condition characterized by the overproduction of thyroid hormones. A typical symptom associated with this condition is weight loss, which occurs despite an increased appetite. The elevated levels of thyroid hormones accelerate metabolism, leading to an increase in energy expenditure. As a result, individuals with Graves' disease often experience significant weight loss over time, even though they may be eating more than usual.

In contrast, symptoms like cold intolerance, fatigue, and sensitivity to heat can be seen in different contexts or conditions. Cold intolerance generally links to hypothyroidism, where an underactive thyroid results in reduced metabolic activity and energy levels. Fatigue is a common symptom in both hyperthyroid and hypothyroid states; however, in the context of Graves' disease, it is not as prominently defining as weight loss. Sensitivity to heat, while encountered in hyperthyroid conditions, typically refers to a discomfort level with heat rather than a significant symptom like weight loss in Graves' disease, which stands out more distinctly due to its direct impact on metabolism.
