Answer 1

Goiter is a common disease resulting from a shortage of dietary iodine. The thyroid gland requires iodine to synthesize T3 and T4 hormones.

Step-by-step explanation:

Goiter is a common disease resulting from a shortage of dietary iodine. The thyroid gland requires iodine to synthesize T3 and T4 hormones. When there is inadequate iodine intake, goiter occurs as a result of overproduction of TSH without the formation of thyroid hormone.
