Umbilical hernias can often be pressed with the hand, but it is important to be careful with the technique and strength used to avoid damaging the contents of the hernia or the local skin, which could lead to a secondary bacterial infection. Umbilical hernia is one of the common diseases during the newborn and infant periods. After the umbilical cord falls off, if the closure of the umbilical ring is incomplete or the tissues around the navel are not sturdy, factors such as frequent crying or constipation can increase intra-abdominal pressure. This can lead to the protrusion of abdominal contents, particularly the small intestine along with the peritoneum and abdominal wall skin, gradually pushing outward at the umbilicus, forming an umbilical hernia.
