Which is a result of consuming a diet deficient in iodine?
A) low plasma concentration of thyroid hormones due to reduced secretion of thyroid-stimulating hormone (TSH) by the pituitary gland
B) low plasma concentration of thyroid hormones and an enlarged thyroid gland
C) high plasma concentration of thyroid-stimulating hormone (TSH) due to a deficiency of thyrotropin-releasing hormone (TRH)
D) high plasma concentration of thyroid hormones due to increased secretion of TSH by the pituitary gland
E) low plasma concentration of thyroid hormones and atrophy of the thyroid gland due to reduced concentrations of thyroid-stimulating hormone (TSH)

Question

Quizplus · Accepted Answer

Consuming a diet deficient in iodine can lead to a condition called goiter, which is an enlarged thyroid gland. This is because iodine is necessary for the synthesis of thyroid hormones, and without enough iodine, the thyroid gland becomes enlarged as it tries to produce more hormones. However, the low production of thyroid hormones also contributes to the symptoms of iodine deficiency. Therefore, choice (B) is the best answer as it includes both the low plasma concentration of thyroid hormones and the enlarged thyroid gland.
