Umbilical hernia generally does not affect a baby's gastrointestinal tract, but we need to avoid the hernia becoming trapped or even rupturing. Once an umbilical hernia has formed, the hernial sac may contain abdominal omentum or possibly intestines. If the intestines become trapped, this can lead to necrosis of the intestines. Generally, patients may experience nausea, vomiting, or even bloody stools. Therefore, umbilical hernias can usually be treated conservatively within the first six months. If the diameter of the umbilical ring is still greater than 1.5 cm after the age of two, we recommend early surgical intervention, as only surgical treatment can cure it. In the treatment process of an umbilical hernia, the conservative treatment methods adopted mainly involve using a coin or a flat board larger than the umbilical ring, wrapping it to press against the umbilical ring, and then securing it with wide tape to prevent movement.
