What may delay the first meconium stool in very low birth weight newborns?

• A. It may be delayed up to 7 days.
• B. It is typically delayed up to 2 weeks.
• C. It always passes within a few hours.
• D. There is no delay in VLBW newborns.

Answer: (A)

In very low birth weight newborns, the gut is immature and intestinal motility is reduced, so the passage of meconium can be significantly delayed. This immaturity means the first meconium stool may not occur until about seven days after birth in some of these infants, which is considered within the range of normal variation for VLBW babies. Saying it will always pass within a few hours doesn’t fit the reality of prematurity, and claiming there’s no delay or that delays routinely extend to two weeks ignores the typical limits of intestinal immaturity.
