Iodine induced hyperthyroidism is a thyrotoxic condition caused by exposure to excessive iodine. Historically this type of hyperthyroidism has been described in areas of iodine deficiency. With advances in medicine, iodine induced hyperthyroidism has been observed following the use of drugs containing iodine-for example, amiodarone, and contrast agents used in radiological imaging. In elderly patients it is frequently difficult to diagnose and control contrast related hyperthyroidism, as most of these patients do not always present with typical signs and symptoms of hyperthyroidism. Treatment can be very challenging as drugs commonly used to treat hyperthyroidism have little effect on already formed thyroid hormone due to iodine excess.
碘致甲状腺功能亢进症是一种因接触过量碘而引起的甲状腺毒症。从历史上看，这种类型的甲状腺功能亢进症曾在碘缺乏地区被描述过。随着医学的进步，在使用含碘药物（如胺碘酮）以及放射成像中使用的造影剂后，也观察到了碘致甲状腺功能亢进症。在老年患者中，与造影剂相关的甲状腺功能亢进症常常难以诊断和控制，因为这些患者大多并不总是表现出典型的甲状腺功能亢进症体征和症状。由于碘过量，常用于治疗甲状腺功能亢进症的药物对已形成的甲状腺激素几乎没有作用，因此治疗可能极具挑战性。
