An Overview of Congenital Hypothyroidism

Congenital hypothyroidism is inadequate thyroid hormone production in newborn infants. It can occur because of an anatomic defect in the gland an inborn error of thyroid metabolism or iodine deficiency. It is called cretinism. Congenital hypothyroidism (CHT) is a condition resulting from an absent or under-developed thyroid gland (dysgenesis) or one that has developed but cannot make thyroid hormone because of a ‘production line’ problem (dyshormonogenesis). Babies with CHT cannot produce enough thyroid hormone for the body’s needs. The term ‘congenital’ means that the condition is present at birth.
