    Study Notes

    Disorders of Glucose Homeostasis in Neonates

    • Glucose is the primary metabolite of the fetus and newborn.
    • During intrauterine life, the fetus relies on the placenta for a constant supply of glucose.
    • At birth, the infant is abruptly removed from the placental environment, triggering hormonal and metabolic changes.
    • These changes facilitate adaptation to extrauterine life and regulate glucose hemostasis.
    • A serum glucose value of [insert value] is a key indicator of glucose homeostasis in neonates.
