Thyroid disease, both thyrotoxicosis and hypothyroidism, are associated with adverse pregnancy outcomes and poor fetal development, including neurocognitive outcomes. Given the importance of understanding physiology, changes during pregnancy, and management, ACOG has published recommendations to guide clinical decision-making.
