Causes of Hyperthyroidism

Most commonly caused by Graves' disease, an autoimmune condition in which antibodies stimulate the thyroid gland to overproduce hormone. Other causes include toxic nodular goitre, where one or more thyroid nodules independently produce excess hormone, and thyroiditis, an inflammation of the thyroid gland that can cause a temporary release of excess stored hormone. Excessive intake of thyroid hormone medication or, rarely, iodine-containing substances can also lead to hyperthyroidism in susceptible individuals.
