As is the case with all surgeries, infection and/or bleeding are two common risks associated with hernia surgery. Also, if you’re an avid smoker and consumes alcohol in excess, and are quite aged, the complications could be worse. Other side effects include injury of the intestines, bladder, blood vessels, etc. along with extended scarring. To understand more about complications, you must consult with your doctor well-in-advance before the surgical process takes place.
