This course reviews how pregnancy alters thyroid physiology and explores the anesthetic implications of both hypo- and hyperthyroidism for mother and fetus. You’ll learn to recognize maternal–fetal risks, interpret disease severity in the context of pregnancy, and tailor anesthetic plans—including monitoring, drug choice, and neuraxial vs general techniques—to safely manage parturients with Graves’ disease, Hashimoto’s, and other thyroid disorders across the perioperative and peripartum period.
