Neonatal hypothyroidism
Alternate Names : Cretinism, Congenital hypothyroidism, Hypothyroidism - infants
Definition
Neonatal hypothyroidism is decreased thyroid hormone production in a newborn. In very rare cases, no thyroid hormone is produced. If the baby was born with the condition, it is called congenital hypothyroidism. If it develops soon after birth, it is referred to as hypothyroidism acquired in the newborn period.
Overview, Causes, & Risk Factors
Hypothyroidism in the newborn may be caused by: - A missing or abnormally developed thyroid gland
- Pituitary gland's failure to stimulate the thyroid
- Defective or abnormal formation of thyroid hormones
Incomplete development of the thyroid is the most common defect and occurs in about 1 out of every 3,000 births. Girls are affected twice as often than boys.
