- 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
