What Is Hypothyroidism?
3. Iodine Deficiency
The thyroid gland needs iodine in order to produce certain hormones. Therefore, the thyroid gland will not be able to produce the hormones it needs if there is not enough of the mineral. This is rare in developed countries where iodine is often added to food to ensure people get enough of it.
Another potential cause is a pituitary disorder. This is a condition with the pituitary gland, which is responsible for releasing a hormone that helps to stimulate the thyroid gland. In some cases, a person will be born with a faulty thyroid gland or even no thyroid gland at all.
