The main symptom of an umbilical hernia is the presence of a swelling or bulge near the navel which ranges from about 1 to 5 cm in diameter.

This may cause death of the trapped tissue (necrosis) and result in severe complications. If you or your baby experience the following symptoms, you should immediately consult your doctor:
