Graves disease falls under which thyroid disorder category?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Goiter without toxicity
• D. Thyroiditis

Answer: (B)

Graves disease is an autoimmune condition that causes the thyroid to produce excess hormones. The antibodies stimulate the TSH receptor, making the gland overactive and leading to hyperthyroidism. That overproduction of thyroid hormones drives the characteristic symptoms—weight loss, heat intolerance, rapid heart rate, and often a diffuse goiter with eye changes. So this condition is categorized as hyperthyroidism, not hypothyroidism, not a non-toxic goiter, and not thyroiditis, which involves inflammation and typically a different pattern of thyroid hormone release.
