Accepted Answer

Goitre. Deficiency of Iodine causes Goitre. Iodine is an important element that thyroid gland needs to make thyroid hormones. If diet is deficient in iodine, thyroid gland will enlarge as it tries to increase the production of thyroid hormones. The enlarged thyroid can cause a mass in the neck known as a goitre. As thyroid levels fall, hypothyroidism develops. Hypothyroidism slows metabolism, causing such symptoms as fatigue, weight gain, weakness, increased cold sensitivity, constipation, dry skin, and depressed mood.
