Infant umbilical hernia is a congenital condition where the abdominal wall muscles around the navel are underdeveloped and weak, causing a protrusion at the umbilicus. This often protrudes more readily when intra-abdominal pressure increases. Therefore, it is important to avoid causing the child excessive crying, and if the child has gastrointestinal symptoms, they should be treated promptly. Furthermore, since over 80% of umbilical hernias close as the child ages, typically by the age of two, as the hernia ring gradually narrows or even closes, special treatment is usually not needed. However, if the umbilical hernia has not healed by the time the child is two years old, or if the diameter of the hernia ring is greater than 2cm, surgery may ultimately be necessary.
