How does iodine block thyroid hormone release?
Effects of Iodine Load A normal thyroid gland responds to iodine load through an intrinsic autoregulatory mechanism, which acutely blocks thyroid hormone synthesis (Wolff-Chaikoff effect) and causes an increase in serum TSH concentration.
How do I prepare for a thyroidectomy?
