Hyperactivity of the thyroid gland associated with Graves disease is called what?

• A. Hyperthyroidism
• B. Hypothyroidism
• C. Goiter
• D. Thyrotoxicosis

Answer: (A)

Graves disease causes the thyroid gland to produce too much thyroid hormone because autoimmune antibodies stimulate the TSH receptor, driving increased synthesis and release of T3 and T4. The term that describes this overactivity of the gland is hyperthyroidism. While the excess hormones can lead to a systemic state called thyrotoxicosis, which is simply the presence of high thyroid hormone levels in the body, the specific functional label for an overactive gland is hyperthyroidism. Goiter is just enlargement of the gland and can occur with Graves, but it doesn’t define the gland’s activity, and hypothyroidism is the opposite—low hormone production.
