I've had mine for over 20 years and I do have a Fistula and Seton. I find that regular and consistent exercise makes my pouch function as good as I think it could ever be. I run usually 20-30 miles a week, less in winter. I'm also a recent vegetarian convert (6 months ago) and I feel like my daily bathroom visits are way down. I'm a little sad I never tracked my BM's but I know i've improved greatly with the diet change also. Scott MC
