I had colectomy 1 year ago due to colonic inertia. I have a j pouch. Im having extremely loud stomach noises no matter if I've eaten or not. I can feel something going on inside when it happens. I have terrible gas 24 hours a day. I can't seem to get things calm. I've tried taking Ibgard and bentyl around the clock. I've tried avoiding caffeine and dairy. I don't know what else to do.....PLEASE ADVISE
