Children with high thyroid stimulating hormone should be alerted to congenital hypothyroidism, and its treatment includes medication, surgery, etc., as prescribed by the doctor. Since thyroid hormone is crucial to brain and nerve development in early childhood, parents should pay close attention to it. If the thyroid hormone is high, a complete set of thyroid function should be done to clarify the type of the disease. Once the diagnosis is confirmed, the patient should be treated with medication, which may include levothyroxine or dry thyroid tablets under the guidance of a doctor. Follow-up visits should be made once every 2 weeks at the beginning of the treatment, and if the T4 level is normal, the follow-up period can be gradually extended and adjusted according to the doctor’s instructions. If thyroid stimulating hormone is seriously high in children, they should consult a doctor and actively cooperate with the doctor’s treatment.
