Graves-Basedow disease. Graves-Basedow disease is an immune disorder of the endocrine system that stimulates and attacks the thyroid gland, being the most common cause of hyperthyroidism. Also known simply as Graves' disease, it occurs most frequently in women (8:1 compared to men) of middle age.
Another sign of Graves' disease is hyperthyroidism, i.e., overproduction of the thyroid hormones T3 and T4. Normal thyroid levels are also seen, and occasionally also hypothyroidism, which may assist in causing goitre (though it is not the cause of the Graves' disease). Hyperthyroidism in Graves' disease is confirmed, as with any other cause of hyperthyroidism, by measuring elevated blood levels of free (unbound) T3 and T4.
