Low Blood Sugar Levels In The Newborn Infant: Do Changing Goal Posts Matter?

Glucose supply and metabolism are essential for growth and normal brain development in both the fetus and newborn. Disorders of glucose availability and metabolism can result in either hypoglycemia or hyperglycemia. The first section of this manuscript will contrast recommendations from the American Academy of Pediatrics and the Pediatric Endocrine Society on the approach to defining neonatal hypoglycemia. Recent studies will be reviewed which add to the controversy. This review aims to discuss the evidence-based guidelines, definitions, pathogenesis, outcomes and management options in this field. The current variations in practices and possibilities of future trials are also addressed.
