I have had a left ovary removed,then hernia repair.Then i had a full hysterectomy,then again hernia repair from that.1 year later hernia repair and a mesh put in place.They seem to go into the same opening each time.The scar is around 4 inches above my belly button.Im overweight.That is a major problem.I need the gastric bypass.Can i still get it with all this history of surgery and a mesh?
