I get the stomach noises too! It is to the point that if I am in class or training for work, I don't eat lunch because it is loud and embarrassing. I don't care what others think, I just don't want to have to explain it. I have a stricture so I do have to be careful of what I eat. The more hydrated I stay the better off I am and the less noises I have going on. I also take VSL 3 Probiotics and they are great. The noises are definitely worse if I eat more carbs and sugar.
Who else had the j-pouch surgery for UC only to find out years later that they have Crohn's? I had my original surgery in 1996 and I have had complications on an off for years. Diagnosed in 2005 with Crohn's.
