Quizplus · Accepted Answer

[IV B 2; Table 7.5]. Graves disease (hyperthyroidism) is caused by overstimulation of the thyroid gland by circulating antibodies to the thyroid-stimulating
hormone (TSH) receptor (which then increases the production and secretion of triiodothyronine $\left(\mathrm{T}_{3}\right)$ and thyroxine $\left(\mathrm{T}_{4}\right)$, just as TSH would). Therefore, the signs and symptoms of Graves disease are the same as those of hyperthyroidism, reflecting the actions of increased circulating levels of thyroid hormones: increased heat production, weight loss, increased $\mathrm{O}_{2}$ consumption and cardiac output, exophthalmos (bulging eyes, not drooping eyelids), and hypertrophy of the thyroid gland (goiter). TSH levels will be decreased (not increased) as a result of the negative feedback effect of increased $\mathrm{T}_{3}$ levels on the anterior pituitary.
