Abstract
Thyroid hormones play a crucial role in maternal and fetal health during pregnancy. Proper thyroid function ensures normal fetal neurodevelopment, regulates maternal metabolism, and supports placental function. Both hypothyroidism and hyperthyroidism can lead to adverse pregnancy outcomes, including miscarriage, preterm birth, preeclampsia, and impaired neurocognitive development in the offspring. This article reviews the physiological role of thyroid hormones during pregnancy, their regulatory mechanisms, and the potential maternal and fetal risks associated with thyroid dysfunction. Understanding these effects is essential for early diagnosis, monitoring, and appropriate therapeutic interventions to optimize pregnancy outcomes.References
