Answer:
Goiter.
Step-by-step explanation:
The thyroid gland is responsible for the secretion of the triidotyronine and thyroxine hormone in the body. The thyroid hormone regulates the metabolism and amount of particular ions in the body.
The iodine acts as the precursor for the maintenance of the thyroxine. The deficiency of the thyroid hormone can cause goiter. The thyroid gland gets swollen and cause problem in the breathing. The production of mucus and cough is common in goiter.
Thus, the answer is goiter.
