Umbilical hernia is a small bulge around the umbilicus (belly button). An umbilical hernia in an infant is caused by the incomplete closure of the muscles around the Umbilicus. Smaller umbilical hernias often require no treatment and get closed by the age of 2 however larger umbilical hernias may necessitate the surgical treatment. Umbilical hernias may also develop later in life during pregnancy. Conditions such as mucopolysaccharide storage diseases, Beckwith Wieldemann syndrome, and Down syndrome may increase the risk of umbilical hernias.
The bulge in umbilical hernia will be soft and bulges may appear when the baby cries or sits up.
