Quizplus · Accepted Answer

Simple goiter is caused by the lack of iodine, which is necessary for the production of thyroid hormones. A deficiency in iodine results in the thyroid gland becoming enlarged as it tries to produce more hormones. High levels of thyroxine in the blood can cause hyperthyroidism, but not simple goiter. The thymus gland is not related to the development of simple goiter.
