Umbilical hernias are generally more common in newborns, primarily because the umbilical ring has not yet completely closed. In children, lumps appear in the navel area when they cry or when abdominal pressure increases. To address an umbilical hernia, first massage the area around the belly button, then gently return the hernial sac to the abdominal cavity with both hands. After returning the hernia, secure it externally with a hernia belt. This can effectively prevent the recurrence of the umbilical hernia. Typically, through conservative treatment, which involves this method of binding for about one to two months, the patient’s umbilical hernia can heal on its own.
