Quizplus · Accepted Answer

A goiter is primarily caused by a deficiency in iodine, not directly by a deficiency in the hormones thyroxine or triiodothyronine. Iodine is essential for the production of thyroid hormones, and its deficiency can lead to an enlarged thyroid gland (goiter) as the body attempts to compensate for the reduced hormone production.
