Infant hypothyroidism

Last edited: 4/14/2026

Overview

Infant hypothyroidism is a condition characterized by insufficient production of thyroid hormones in infants, leading to developmental delays and other health issues if left untreated. Early detection and treatment are crucial for preventing long-term complications 25.

Diagnosis

  • Elevated TSH levels with low T4 concentrations in blood tests 25.
  • Clinical signs may include feeding difficulties, constipation, lethargy, and delayed growth 25.
  • Newborn screening programs often identify cases through heel prick tests 25.

    • Management

  • Initiate levothyroxine replacement therapy, typically starting at 10-15 μg/kg daily, adjusted based on TSH and T4 levels 25.
  • Regular monitoring of thyroid function tests (TSH, T4) every 1-2 months in the first year, then every 3-6 months thereafter 25.
  • Ensure adequate dose titration to maintain euthyroidism 25.

    • Special Populations

  • No specific guidelines provided in the abstracts for pregnancy, pediatrics beyond infancy, elderly, or comorbidities related to infant hypothyroidism [].

    • Key Recommendations

  • Screen all newborns for congenital hypothyroidism as part of routine newborn screening programs (Evidence: Strong 25).
  • Initiate levothyroxine therapy promptly in confirmed cases, starting at 10-15 μg/kg daily, and adjust based on clinical response and laboratory values (Evidence: Strong 25).
  • Regularly monitor thyroid function tests in infants with hypothyroidism to ensure proper dosage and maintain euthyroid status (Evidence: Strong 25).
