Stephanie,
Yes, surgery can affect you in all different ways. I've had around 15-Surgeries. Just this year 2-surgeries, Loop ileostomy, and shoulder surgery. In September another surgery to make ileostomy permanent. A year ago my colon tore thru my vaginal wall and my colon and bladder fell out of me.
I know being ill with things, pain then surgery is a lot for a person's body to go thru. But I would recommend at least notifying you Doctor so they are aware in case you need to talk with them or have medication changes.
Good luck to you.
