Which disease can be caused by iodine deficiency?
Answer and explanation
Correct answer: Goitre
Iodine is needed by the thyroid gland to synthesise thyroxine. When iodine intake is insufficient, thyroxine production may fall and the thyroid can enlarge in an effort to capture more iodine; this swelling is called goitre. Therefore, option A is correct. Diabetes is associated with impaired insulin regulation, night blindness commonly with vitamin A deficiency, and asthma with airway inflammation.
