Iodine repletion syndrome refers to the adverse effects that can occur when individuals with iodine deficiency begin to receive adequate amounts of iodine. While iodine supplementation is important for correcting deficiency, sudden or excessive repletion can lead to thyroid dysfunction, including hyperthyroidism or autoimmune thyroiditis. This phenomenon is particularly relevant in regions where iodine deficiency is prevalent and sudden introduction of iodized salt is implemented.
