Umbilical hernia in infants is considered a congenital developmental disease, caused by the incomplete development of the abdominal wall at the navel, leading to protrusion, especially noticeable when the baby cries or has a cold. Generally, special treatment is not necessary, as about 80% of infants will see the hernial ring gradually decrease in size or even close by the age of two, achieving self-healing without the need for special intervention. However, treatment is required for a small fraction of children whose hernial ring diameter is greater than 2cm, or who still exhibit a noticeable umbilical hernia after the age of two. Without treatment, there is a risk of incarceration, which can also cause abdominal discomfort in the child, poor digestion, and other symptoms.
