A hernia is a hole or weak spot in muscles. Sometimes organs in your belly, most likely part of the intestines, push through this spot.
The umbilicus is the belly button. Some babies are born with a small opening in the belly muscles near the belly button. An umbilical hernia is when part of your child’s intestine bulges through this opening.
Umbilical hernias may not cause any symptoms.
They cause a soft bulge. The bulge is usually there all the time or may be there only during coughing or straining when passing stool. Sometimes, there's no bulge but the doctor can feel a hole in the muscle.
