What is a key feature of Graves disease?

A key feature of Graves' disease is hyperthyroidism, which is characterized by an overproduction of thyroid hormones. This condition occurs due to an autoimmune response where the body's immune system mistakenly attacks the thyroid gland, leading to its overactivity. As a result, individuals with Graves' disease often experience symptoms associated with hyperthyroidism, such as weight loss, increased heart rate, anxiety, heat intolerance, and, most notably, an enlarged thyroid known as a goiter.

While goiter is also a significant feature of Graves' disease, the defining characteristic is the excessive production of thyroid hormones, making hyperthyroidism the most critical aspect of the condition. Other options, such as hypoparathyroidism and uremia, are unrelated to Graves' disease and do not describe its features or symptoms. Understanding hyperthyroidism's role in Graves' disease is essential for recognizing how the condition affects the body and its overall metabolism.
