Patients with autoimmune thyroid disease and those taking medications that affect thyroid function are prone to hyperthyroidism. Patients with autoimmune thyroid disease or a family history of autoimmune thyroid disease are predisposed to hyperthyroidism, such as Graves’ disease itself, which is also an autoimmune thyroid disease and has a genetic predisposition, often with familial onset. Some patients with cardiac arrhythmia need to take amiodarone, which contains 75 mg of iodine in 200 mg, and if patients take it for a long period of time, it can lead to excessive iodine intake, which is likely to induce hyperthyroidism. Therefore, if you suffer from autoimmune thyroid disease or family history and take drugs that affect thyroid function should be careful to screen for hyperthyroidism. Seek medical attention when symptoms occur.
