Congenital hypothyroidism

Congenital hypothyroidism (CH) is a thyroid hormone deficiency present at birth. If untreated soon after birth, severe congenital hypothyroidism can lead to growth failure and permanent intellectual disability. Untreated congenital hypothyroidism is also referred to as cretinism. Infants born with congenital hypothyroidism may be asymptomatic, or may display mild symptoms that go unrecognized as a problem. Significant deficiency may cause excessive sleeping, reduced interest in nursing, poor muscle tone, low or hoarse cry, infrequent bowel movements, significant jaundice, and low body temperature.
