Infant umbilical hernia is caused by congenital weakness of the umbilical and abdominal regions, resulting in protrusion of the navel. Generally, it does not require special treatment. This is because up to 80% of infant umbilical hernias will gradually decrease in size as the child ages and physically develops, and the hernial ring may even close, thereby healing naturally. Surgery is usually chosen only if the diameter of the hernia ring is too large, especially if it is more than 2 cm, or if the child is over two years old and still has a noticeable umbilical hernia. Before this, it is usually advisable to avoid situations that could increase abdominal pressure in the child, such as preventing prolonged and intense crying. If the child has gastrointestinal symptoms, they should be treated promptly and actively to prevent repeated protrusion of the umbilical hernia.
