Thyroid autoantibodies are found to be more prevalent in geographical areas with a higher dietary iodine levels. Several mechanisms by which iodine may promote thyroid autoimmunity have been proposed:
Excessive iodine intake presents symptoms similar to those of iodine deficiency. Commonly encountered symptoms are abnormal growth of the thyroid gland and disorders in functioning, [ 78 ] as well as in growth of the organism as a whole.
[1] [7] Other causes include multinodular goiter, toxic adenoma, inflammation of the thyroid, eating too much iodine, and too much synthetic thyroid hormone. [1] [2] A less common cause is a pituitary adenoma. [1] The diagnosis may be suspected based on signs and symptoms and then confirmed with blood tests. [1]
As a result, amiodarone therapy elevates free circulating iodine levels up to 40 times greater than the iodine intake from the average American diet. [2] Iodine plays a role in thyroid production, and excess iodine levels within the body can result in overproduction of thyroid hormone.
The hyperthyroidism usually develops over 2 to 12 weeks following iodine administration. [ 2 ] In some ways the Jod-Basedow phenomenon is the opposite of two physiological compensation mechanisms, the Plummer effect and the Wolff–Chaikoff effect , which in normal persons and in persons with thyroid disease, suppress the thyroid hormone after ...

If goitre is caused by iodine deficiency, small doses of iodide in the form of Lugol's iodine or KI solution are given.
