The following is a possible progression of which of the following disorders: Inadequate dietary iodine intake → low level of thyroid hormone in blood → increased TSH secretion → thyroid gland enlargement.

Question

Quizplus · Accepted Answer

Inadequate iodine intake leads to low levels of thyroid hormone in the blood, which stimulates the pituitary gland to secrete more thyroid-stimulating hormone (TSH). This excess TSH causes the thyroid gland to enlarge, leading to a goiter. Acromegaly is caused by excess growth hormone, tetany by low levels of calcium in the blood, Cushing's syndrome by excess cortisol secretion, and Addison's disease by low cortisol and aldosterone levels.
