Hyperthyroidism epidemiology

A summary of the occurrence and epidemiology of iodine-induced hyperthyroidism has been published (41), based on the authors experience in Tasmania, Zaire, Zimbabwe, and Brazil. Another review has more specifically examined the cardiac features of iodine-induced hyperthyroidism and has emphasized the importance of awareness, monitoring, and treatment of such hyperthyroidism in areas in which iodine supplementation has been recently introduced (42).

The thyroid gland seems to be well adapted to incidents of iodine intake in very high amounts. Still, there is evidence showing that increased intake of iodine may induce clinically relevant problems in some susceptible subjects. These effects are optimally identifiable at population level, as individual responses vary depending on many other factors that are difficult to control. One of the main undesirable consequences of increased iodine intake in a population is a higher incidence of hyperthyroidism. This chapter discusses the epidemiology and etiology of iodine-induced hyperthyroidism (IIH), which follows normalization of iodine supply.
