Since I have great disease control and no side effects, why on earth would I discuss an ileostomy? I am much, much healthier than before my surgery, in spite of the long-term antibiotic use. Pouch failure is when all reasonable treatments have been exhausted.
I’m not prone to yeast infections, but you could potentially manage those with something like miconazole (Monistat) instead of planning to suffer. It’s possible that a strong bacterial probiotic, like Visbiome, might help reduce that side effect. I do take a high dose of VSL #3, well separated from my antibiotic doses, mainly to provide additional support for pouchitis control.
