Pictures & ImagesUmbilical hernia
An umbilical hernia is a protrusion of the peritoneum and fluid, omentum, or a portion of abdominal organ(s) through the umbilical ring. The umbilical ring is the fibrous and muscle tissue around the navel (belly-button). Small hernias usually close spontaneously without treatment by age 1 or 2. Umbilical hernias are usually painless and are common in infants.
