Toxic nodular goiter; iodine-induced hyperthyroidism
Increased occurrence of hypothyroidism in moderate-to-severe iodine deficiency; decreased occurrence of hypothyroidism in mild-to-moderate iodine deficiency
Other forms of thyroid problems, namely iodine-induced hypothyroidism, autoimmune thyroiditis, and hyperthyroidism associated with excessive iodine intake, have become a greater concern than deficiency disorders.1
