Can you tell me is hernia a possible cause of abdominal part swollen?

Hernia Bulge. One of the most common signs of a hernia is a bulge in the area of the hernia. A hernia is a defect/hole in the abdominal wall. As a result the contents of the abdomen push through this defect and create swelling in the area. While this may only represents fat from inside the abdomen, sometimes it is intestine. Hernias should be evaluated by your physician and most should be repaired surgically.
