Every human has a gut that makes all kinds of noises.Colon noise is a result of it moving stuff around, not any disease or anything deadly.IBSers sometimes don't move things around in there quite like they did when healthy so it makes more noise, but some healthy people have very noisy guts from time to time.The only dangerous noise is complete silence even when they put a stethoscope to your belly. That means a complete obstruction.I know the noises are embarrassing and worrying, but really it is just means the colon is on the job and working. It just does it louder in some people and at some times. It is like your heartbeat. If you want stuff to move (stool, blood) there is going to be some noise.
