|The Thyroid Gland|

- Subacute thyroiditis—This occurs when there is inflammation of the thyroid gland after a viral upper respiratory tract infection.
- Drugs—Drugs used to treat hyperthyroidism such as lithium (used to treat certain psychiatric disorders), certain cardiac medicines, and other medicines (interleukins, alpha interferon).
- Medical treatments—Treatments include radiation or surgical removal of part of the thyroid gland (called subtotal thyroidectomy) to treat other thyroid diseases.
- Idiopathic thyroid atrophy—The thyroid tissue shrivels up (atrophies) for unknown reasons.
- Iodine deficiency—The thyroid gland does not get enough iodine to produce thyroid hormone (this is rare in the United States).
- Iodine excess—Certain foods (such as shellfish) and certain medicines (such as cough medicine) contain large amounts of iodine, which can block thyroid hormone production (rare).
- Infiltrative illnesses—Cancers and certain infections.
- Pituitary adenoma—A benign tumor of the pituitary gland that can cause a problem signaling the thyroid to make thyroid hormones.
- Postpartum thyroiditis—This condition usually improves but may be long lasting.
- Congenital hypothyroidism—An infant that is born with problems making normal amounts of thyroid hormones.
