I've had a j-pouch for 6.5 years now, and I'm going to start my first probiotic treatment next week. The one I'm starting has 6 different humanized strains, which all live in different parts of the track. Also, wouldn't the flora level of the pouch itself would be similar to the flora that would live in the colon, as it takes over the job of it? I would think having more happy bacteria than bad would lead to a healthy flora count thus stopping pouchitis (which is caused by too much bad bacteria, or even an antibiotic treatment can trigger it), being with it in itself.
I'm currently taking cipro and flagyl twice a day for pouchitis, so I'm going to start adding the probiotic near the end of their course. I hope to have a positive experience using them.
