I believe I have this disease, getting tested soon, were your symptoms like mine?

almost every time after i eat a meal (especially large ones) about an hour or 2 later i feel an immense pressure in my abdomen (bloating?) and it is much harder to breathe than it was before I consumed the meal, & it seems worse after certain things like last night i had a small pepperoni pizza and it was BAD

I believe this is because of 1 of 3 things

  1. I have had unmedicated GERD for a while now and I eventually will get on a PPI (this might fix it altogether)

  2. I am simply overeating, when I'm hungry its really hard to say no to food and just stuff my face, I.E. eating an entire small pizza last night when really a couple slices or 3 would have been fine, my stomach is just simply getting too full and thus pushing on my diaphragm making it harder to breathe

  3. I have celiac disease and/or an intolerance to wheat/gluten, this would explain why it was so bad after i ate the pizza last night, to test this out i ate a can of green beans for lunch today and now about 3 hours after eating it I dont feel any adverse affects like I did from the pizza

This has been happening for a few years now and after multiple tests and dr visits my dr cannot figure out whats going on, but we've never discussed celiac or even anything to do with gluten intolerance..

Was bloating and SOB after meals any of your primary symptoms that eventually got you diagnosed?
