Question
What causes neonatal umbilical hernia?
Answer
The causes of neonatal umbilical hernia are primarily due to developmental defects in the umbilicus, resulting in an unclosed umbilical ring, or poor adhesion and healing of the umbilical cord root tissue and the umbilical ring after cord detachment. Under conditions of increased intra-abdominal pressure, the peritoneum or intestines may protrude through the weak spot of the umbilicus, forming an umbilical hernia. Most newborns with umbilical hernia do not experience discomfort, although a very few may feel discomfort due to regional swelling.
