Just got back from first post-op visit.....
Don't feel bad!!! I went for my post-op a week after surgery and had gained 10 pounds, however, my Dr. assured me that this was due to fluids, I have CHF and have to take diaretics. Within 5 days, after taking my diaretics, I had lost 20 pounds (not counting the additional 10). WOW!! Good Luck and don't worry, it will come off.
