Several factors can lead to transient hypothyroidism in newborns:
1. Maternal Factors: The use of maternal antithyroid medications during pregnancy can suppress thyroid function in the neonate. 2. Iodine Deficiency or Excess: Both a deficiency and an excess of iodine can disrupt thyroid function. 3. Premature Birth: Premature infants are at a higher risk due to immature thyroid glands. 4. Maternal Autoimmune Disorders: Conditions such as Hashimoto's thyroiditis can affect the neonate's thyroid function.
