I have the same problem with loud, embarrasing noises. I have been working very hard to try and locate what causes them, but changes in my diet don't seem to help. I was diagnosed with crohns disease at a young age and never had this problem until i was about 18. Its been 3 years, and they haven't stopped yet. I can't even go to a movie theater or anywhere quiet anymore because i am so worried about my gut making loud sounds. My doctor told me the noises may not go away because there are narrow spots in my digestive tract caused by my disease. Good luck finding a fix, send any good info my way please.
