Umbilical hernias can be massaged back into the abdominal cavity, but if the hernia suddenly becomes hard, or increases in size significantly and cannot be reduced promptly, careful observation is needed to determine if incarceration has occurred. If incarceration persists for too long, it might lead to intestinal necrosis or rupture. Generally, umbilical hernias can self-heal within six months through conservative treatment. If the diameter of the umbilical ring still exceeds 1.5 centimeters after the age of two, it is advised to opt for surgical treatment. For patients over five years old, surgery is recommended under any circumstances. In conservative treatment of umbilical hernias, the most common method involves using an object larger than the umbilical ring, such as a coin or cardboard, wrapped and fixed to the umbilical area, then secured with adhesive tape to prevent movement. Generally, this treatment method is quite effective.
