I don't know (or remember) if you have a k pouch or a BCIR....but here goes. Gurgles and noise is often caused by gas and liquids more so than other stuff...So, firstly...I wouldn't personally care (I am a teacher and honestly it has never been a problem...students fart & burp in class, other teachers have less than perfect etiquette and make noises and in social situations like dinners, coctails and weddings I figure the gurgles are so much better than total incontinence that it is fine ), secondly you can limit to a certain degree some bowel noises with probiotics, a limited diet (I eat mostly protiens and fruits & veggies and very little dairy or starches which means that my output is not gassy nor too noisy (then again I no longer notice it).
What goes in must come out. Dairly makes gas. Milk is a killer (sounds like the rushing rapids in there when I drink a latte) and pizza could turn my pouch into a brass band...
Try dissociating food groups for a day or 2 to see if it helps.
Just protiens in one meal, just pasta in another...it may help.
If not there is always beano or other gas reducers.
