Study Notes
Disorders of Glucose Homeostasis in Neonates
- Glucose is the primary metabolite for the fetus and newborn during intrauterine life.
- The fetus relies on the placenta for a constant supply of glucose during intrauterine life.
- 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 levels.
- A serum glucose value is a crucial indicator of glucose homeostasis in neonates.
