Umbilical hernias can heal on their own, but we need to choose the appropriate method during the treatment process. Generally, if the umbilical hernia occurs before the age of two, we can choose a coin larger than the umbilical ring or a flat board, wrap it in gauze to press against the umbilical ring, and then use tape to secure it to prevent it from moving. In such cases, the hernia may heal on its own. During the observational treatment of an umbilical hernia, it is also important to prevent the child from engaging in vigorous activities or crying. If the diameter of the umbilical ring exceeds 1.5cm after the age two, we recommend choosing surgical treatment. Generally, if the umbilical hernia has not healed by the age of five, we actively recommend opting for surgical treatment. If the child's improper lifestyle can cause aggravation or even rupture of the umbilical hernia, emergency surgery is required in such cases.
