If the umbilical hernia becomes hard, it may indicate that it has become incarcerated. In such cases, vigorous activities should be avoided and one should rest appropriately or try to manually reduce the protruding hernia sac back into the abdominal cavity. In this situation, close observation is needed to check for intestinal necrosis or even rupture of the hernia.

Generally, for umbilical hernias, most children can heal naturally within two years, particularly within the first six months if conservative treatment is chosen. One can use a coin or a piece of paper larger than the umbilical ring, wrap it around, press it against the umbilical ring, and then secure it with adhesive tape to prevent movement, which generally leads to healing within six months.

If the umbilical ring still has a diameter greater than 1.5 cm after two years, surgical treatment is recommended as early as possible. If the child is over five years old and the umbilical hernia has not healed, timely surgical intervention should be chosen.
