An epigastric hernia occurs when the inside layers of the abdominal muscle have weakened. It can be caused due to aging, injury, an old incision or a weakness present from birth resulting in a bulge or tear in the wall of the abdomen between the umbilicus (belly button) and sternum. This allows a loop of intestine or abdominal tissue to be pushed into the sac. Most epigastric hernias are treated with a surgical correction either with an open approach or a laparoscopic approach. A piece of mesh is placed inside the abdomen and is held in place with the help of sutures through the muscle layers and surgical tacks around the edges of the mesh.
