My wife has had severe bloating accompanied with loud audible sloshing sounds. She's of average height and weight. Wondering what could be causing her discomfort. She has been tested for lactose intolerance and gluten intolerance and both have come back negative. She's had her gallbladder tested and those tests were inconclusive as well. All anyone can tell us right now is that it might be IBS or some other food allergy. If you have any insight as to what our next steps are, then please let me know.
