What weight classification requires close monitoring for hypoglycemia after birth?

• A. Small for gestational age
• B. Average for gestational age
• C. Large for gestational age
• D. Underweight for gestational age

Answer: (C)

The classification that requires close monitoring for hypoglycemia after birth is large for gestational age (LGA). Infants who are large for their gestational age, typically defined as being above the 90th percentile for birth weight, are at an increased risk for several metabolic complications, one of which is hypoglycemia.

This increased risk for hypoglycemia is related to several factors. LGA infants might be born to mothers with diabetes, which can lead to elevated insulin levels in the newborn as a compensatory response. After delivery, when the maternal glucose supply is abruptly cut off, these infants may have high levels of circulating insulin but insufficient glucose available, leading to symptoms of hypoglycemia.

In contrast, the other weight classifications may either not show a significant risk for hypoglycemia or have different associated concerns. Small for gestational age (SGA) infants might have different metabolic needs due to underdevelopment, while average for gestational age (AGA) infants generally have a stable metabolic response post-delivery. Underweight for gestational age can also present different challenges, but the hypoglycemia risk is notably higher in LGA infants due to the factors mentioned. Consequently, close monitoring in the immediate postpartum period is crucial for LGA infants
