Disease overview

Hypothyroidism is an endocrine disease wherein the thyroid gland does not produce enough thyroid hormone, resulting in an imbalance affecting a wide variety of body functions. Most frequently, hypothyroidism in cats has iatrogenic causes - it can occur after iodine-131 therapy, antithyroid drug therapy or thyroidectomy. The congenital form of hypothyroidism in cats is very rare.
