Answer 1

The most common symptom of an iodine deficiency in an adult is goiter, which is an enlargement of the thyroid gland. Iodine is essential for the synthesis of thyroid hormones, and when there is a deficiency, the thyroid gland may enlarge in an attempt to capture more iodine from the bloodstream. Other symptoms of iodine deficiency may include fatigue, weight gain, and sensitivity to cold, but goiter is the most characteristic physical sign.
