The Wolff—Chaikoff effect discovered by Drs. On the other hand, when thyrocites have low iodine levels and are exposed to a high iodine concentration, they increase significantly their production of thyroid hormone thus leading to hyperthyroidism, a phenomenon known as Jod-Basedow effect.
Iodide induced hyperthyroidism with computed tomography contrast fluids.
However, unlike the Wolff-Chaikoff effectthe Jod-Basedow effect does not occur in persons with normal thyroid glands, as thyroid hormone synthesis and release in normal persons is controlled by pituitary TSH secretion which does not allow hyperthyroidism when extra iodine is ingested.
