Graves disease most commonly causes which thyroid condition?

• A. Hypothyroidism
• B. Hyperthyroidism
• C. Euthyroid
• D. Thyroid cancer

Answer: (B)

Graves disease is an autoimmune condition where antibodies stimulate the TSH receptor on the thyroid, driving the gland to overproduce thyroid hormones (T3 and T4). This pushes the body into a hyperthyroid state, which is why Graves disease most commonly causes hyperthyroidism. It’s the leading cause of endogenous hyperthyroidism in adults, often with a diffusely enlarged thyroid and may include eye signs like exophthalmos. The other options don’t fit because hypothyroidism would mean too little hormone, euthyroid means normal thyroid function, and thyroid cancer does not typically cause systemic overproduction of thyroid hormones.
