Graves disease is best described as an autoimmune hyperthyroidism with goiter and hyperthyroid symptoms including tachycardia, tremor, heat intolerance, and ocular changes.

Graves disease is best described as an autoimmune hyperthyroidism with goiter and hyperthyroid symptoms including tachycardia, tremor, heat intolerance, and ocular changes.

• A. Autoimmune hypothyroidism due to iodine deficiency
• B. Autoimmune hyperthyroidism with goiter and ocular findings
• C. Secondary hypothyroidism from pituitary failure
• D. Non-thyroid illness syndrome

Answer: (B)

Graves disease is an autoimmune process in which antibodies stimulate the TSH receptor on thyroid cells, causing overproduction of thyroid hormones and a diffuse goiter. The resulting hyperthyroidism brings tachycardia, tremor, heat intolerance, and other hypermetabolic symptoms, while eye findings come from autoimmune involvement of orbital tissues leading to edema and ophthalmopathy. This description fits Graves, unlike autoimmune hypothyroidism (Hashimoto) which causes hypothyroidism rather than hyperthyroidism; secondary hypothyroidism from pituitary failure, which would show low thyroid hormones without hyperthyroid symptoms or eye signs; or non-thyroid illness syndrome, which involves altered thyroid tests due to illness rather than an autoimmune hyperthyroid process with orbital involvement.
