Goiters are a relatively common condition, and the most common cause of goiters is iodine deficiency, which affects an estimated of about 2.2 billion population. The incidence of goiter is 5-20% population, with mild iodine deficiency. The prevalence increases to 20-30% with moderate iodine deficiency, and the incidence increases to greater than 30% with severe iodine deficiency [1].
