Which of the following conditions can lead to delayed stool passage in neonates?

• A. Meconium ileus
• B. Overfeeding
• C. Infection
• D. Neonatal jaundice

Answer: (A)

Meconium ileus is a condition that can lead to delayed stool passage in neonates due to a blockage in the intestine caused by thick, sticky meconium. This blockage prevents normal bowel movements, resulting in an inability to pass the first stool, typically meconium, in a timely manner after birth. It is often associated with cystic fibrosis and can present shortly after birth, making it a significant concern in the neonatal period.

Other conditions listed, while they may affect gastrointestinal function or overall health, do not directly cause delayed passage of stool in the same manner as meconium ileus. Overfeeding might lead to other gastrointestinal disturbances but does not typically result in obstruction. Infection could impact overall gastrointestinal motility but isn't a direct cause of delayed stool passage like meconium ileus. Neonatal jaundice, while common, doesn't influence the actual passage of stool, as its primary concern lies in bilirubin metabolism and can lead to complications like kernicterus if untreated but not a direct delay in stool passage. Thus, meconium ileus stands out as the condition specifically linked to delayed stool passage in neonates.
