I get a very nauseous and sick feeling maybe once every week or 2, and I don’t know what is wrong. I’ve tried to pin point if it’s a certain food I eat but there doesn’t seem to be a pattern. I don’t normally go #2 very often , maybe every 3 days, and then when I get sick I get diarrhea and almost throw up. I’ve looked up symptoms for Celiac disease and I have most of them , but I’m not really sure if that’s it or not.
