I had a j pouch (in 2 stages) formed 25 yers ago. Like mot people it took a while to adjust but I have led a busy and full life ever since! I take immodium daily and codeine phosphate at night to absorb water and reduce bowel movements. I eat and drink normally and if I have a not so good day I adjust my diet accordingly.
12 years ago I had problems with fistulas forming firstly to the vaginal wall then to the buttock, presenting with a surface abscess. Major surgery and a complete revamp of my pouch (yes with a temporary ileostomy again) did the trick. I was re-joined 2 months later and have never looked back.
We 'pouchees' have a lot to cope with but better than the alternative and I am eternally grateful for my j pouch.
My advice to anyone is do not give up and stay positive.
