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.
