Repeated measurements chronic hypothyroidism in children thyroid antibodies during the follow-up do not contribute to the management of SH. Hypothyroidism results when the thyroid gland fails to produce enough hormones. By contrast, long-term prognosis of thyroid function was found to be significantly more severe in the children with mild but HT-related SH Figure 1.
