Umbilical hernia in newborns can heal on its own. Cases where the baby's intestines are trapped, causing necrosis, are very dangerous and require immediate hospital examination and treatment.

Protruding navel in newborns, also known as umbilical hernia, is an abnormal bulge caused by part of the abdominal mucosa, intestines or fluid coming out, passing through the abdominal wall muscles and protruding through the newborn's navel. Umbilical hernia is quite common and low birth weight and premature babies are more susceptible to umbilical hernia.
