Umbilical hernia refers to the protrusion of abdominal contents through the umbilical ring. Mostly seen in infants and young children, a majority of umbilical hernias can gradually heal through the contraction of the umbilical fascial ring. Therefore, before the age of two, except in cases of incarcerated hernias, most are treated non-surgically to promote healing. If the child is over two years old and the diameter of the hernia exceeds 1.5 cm, surgical treatment is adopted. After surgery, it is necessary to persist with abdominal muscle exercises to increase the child's resistance, prevent an increase in intra-abdominal pressure, reduce the recurrence of infantile umbilical hernias, and in terms of diet, it is advisable to avoid foods that might cause constipation.
