In neonates, increased bowel sounds come from heightened peristaltic activity as the bowel attempts to move contents past an obstruction or irritation. Malrotation with midgut volvulus can create a mechanical obstruction that prompts ongoing, vigorous peristalsis, so you may hear more active bowel sounds early in the course. This pattern fits best with an obstructive process caused by abnormal intestinal rotation and twisting.

Meconium ileus and necrotizing enterocolitis often present with abdominal findings that progress toward decreased or absent bowel sounds as the condition evolves (distension with advancing obstruction or necrosis). A high-fat diet in neonates isn’t a typical cause or relevant clinical scenario for this age group.
