Hernia Belly Button Underlying Cause
In order for an umbilical hernia to form, there must be a hole, tear or weakened area in the abdominal wall near the umbilicus. This abnormal weakness allows the intestine to protrude through the hole or tear. The intestine forms a bulge underneath the skin.
Causes for weakness in the wall of the abdomen include:
- Birth defect:
- The tissue that surrounds an organ develops abnormally
- Abdominal injury
- Abdominal surgery
