Hi Brian,
I have constant bowel noises-for me, it's the worst part of this disease as it makes it obvious to everyone that there's something wrong and i feel i can't get too close, physically, to people as i get embarressed. im pregnant at the moment so this problem is on the back burner but i'm going to tackle it in the new year as it's been years since i had an examination so it could be due to narrowing.
Anyway, i've done some research over the years and there's lots you can try. I think the main thing is playing with your diet and eating natural yoghurt daily. If you type 'noisy abdomen' into google, there's a massive thread all about this problem-you might find some ideas of things to try from there. Good luck and if you find a cure, please let me know!xx
