Umbilical hernia refers to a bulge formed by the contents of the abdominal cavity protruding through a weak spot in the navel area, commonly seen in infants and young children. Most umbilical hernias can heal on their own within the first year as the umbilical fascial ring gradually contracts. Therefore, unless there is incarceration of the hernia, it is possible to observe and use non-surgical treatment before the age of two. When the child reaches two years of age and the diameter of the hernia exceeds 1.5 centimeters, surgical treatment is recommended. After the surgical treatment of the umbilical hernia, the bulge on the belly button will disappear. The surgery involves making a small incision at the lower edge of the navel, freeing the hernial sac, repositioning the herniated contents, and after excising part of the hernial sac at the hernial ring, suturing is performed.
