Got my j-pouch in 2002 at the age of 29. I was thin before my j-pouch surgery and stayed thin after my j-pouch surgery. It was not until I got pregnant that I gained weight. I did gain 42# during my pregnancy. I did not worry about the weight coming off. All 42# eventually fell off after a little less than 2 years. I am now back to my pre-pregnancy weight. I am currently 127#.
