Have you had you gall bladder checked? there is a test they can do in the hospital that can tell you if your gall bladder is not functioning correctly----I have had one done -------
Have you ever heard of IBS (irritable bowel syndrom)? does caffine or stress activate it more? IBS comes with gas, bloating, abdominal "growling", diarrea and/or constipation. It will make noices as if there is air passing through your intestines. may want to look into this with a good gastrologist Doctor. Good Luck Steven, and God Bless.......RaSMaN
