What Is Hypothyroidism?
2. Thyroid Surgery
Hypothyroidism is also sometimes caused by surgery to the thyroid gland. Another potential cause is radiation treatment that is often used to help treat certain cancers. Radiation treatment can cause hypothyroidism if the thyroid gland is exposed to the radiation. Certain medications can also cause hypothyroidism, including some that are used to treat psychiatric patients.
Hypothyroidism is also sometimes caused by treatment of hyperthyroidism. In attempting to bring the production of certain hormones down to normal levels, the treatment can sometimes be too effective. This can result in the patient developing hypothyroidism permanently, so it is important to not overdo it.
