Question
If a newborn is diagnosed with an umbilical hernia, are family members worried that it might lead to vomiting?
Answer
Umbilical hernias typically do not cause neonatal vomiting. They may cause regional pain when the hernia contents and sac become adhered, and occasionally result in abdominal bloating and vomiting, although incarceration is rare. The main manifestation of an umbilical hernia is swelling at the umbilicus, appearing hemispheric, with the umbilicus protruding and the skin becoming tense and slightly blue when the baby cries. The swelling will contract or disappear when the baby is calm or lying flat. Most umbilical hernias will heal naturally within one year, so it is recommended to avoid allowing the baby to cry vigorously to prevent increased abdominal pressure. While an umbilical hernia itself does not cause vomiting, vigorous crying may trigger reflex vomiting.
