It's been a long time since I had my surgery, but I remember being very bloated for a long time. Your body has had a M a j o r Surgery and it takes a long time for some to recover. I was one of those and the fact that I was very underweight and thin at the time of surgery also showed that I was more bloated. Believe me, once you are up and moving around and carrying on with life, the swelling eventually goes away.
Best of luck to you and please keep us posted.
