I have had all that done and the end result is “well it might be just food allergies.” I am a vegetarian- on a low FODMAP diet, gluten free diet, no fried foods or alcohol- and find eating raw vegetables like a salad even too hard on my stomach. But I will ask about the fluid - she did not say anything about that. To be honest I gave up on the doctors and trying to find the answers myself because all these test and still no answers.
