Treatment for congenital hypothyroidism in children includes medication, etc. Children should be treated as prescribed by their doctor. Congenital hypothyroidism is a condition in which the thyroid gland is not functioning properly due to congenital factors such as thyroid deficiency and thyroxine anabolism. Early manifestations of congenital hypothyroidism are atypical, such as constipation, jaundice, abdominal distension, thinning of hair, etc. Late manifestations may include mental retardation and short stature. Congenital hypothyroidism can be treated with medication. Currently, replacement therapy is mainly used, and the main replacement drug is levothyroxine. Through the appropriate amount of levothyroxine replacement therapy, the missing thyroxine can be supplemented, thus promoting the growth and development of the child. After a period of Levothyroxine replacement therapy, the thyroid function of the child should be rechecked, and if it is normal, the dosage can be reduced or even stopped under the guidance of the doctor. Regular follow-ups are required, and intervention should be made if necessary.
