Which symptom is not typically associated with Graves' disease?

Graves' disease is an autoimmune condition that results in hyperthyroidism, characterized by an overactive thyroid gland. The symptoms associated with this condition often stem from increased levels of thyroid hormones in the body, which can lead to various systemic effects.

Increased appetite is a common symptom of hyperthyroidism. As the metabolism speeds up, individuals may experience a greater drive to consume food, making this symptom typical in Graves' disease.

Similarly, a racing heart, or tachycardia, is a hallmark symptom of hyperthyroidism. The elevated thyroid hormones result in increased heart rate and palpitations as the body's metabolism accelerates, putting additional stress on the cardiovascular system.

Weight loss is also frequently observed in patients with Graves' disease, despite an increase in appetite. This paradox occurs because the body’s heightened metabolism causes it to burn calories more quickly than normal, leading to weight loss.

In contrast, a rash is not a typical symptom associated with Graves' disease. While some autoimmune diseases can cause a rash, the specific symptoms attributed to Graves' disease primarily revolve around the hyperthyroid state and do not typically include dermatological manifestations like rashes. Hence, this is the symptom that stands out as not being characteristic of Graves' disease.
