(had taken Klean prep for the colonoscopy and upper GI then due to snow it was cancelled) Yesterday i ate throughout the day normally when i found that i would be waiting till next week for the procedure that was cancelled.I ate pasta, wholemeal bread and some soup. After a few hours i got really bad abdominal discomfort, bloat, gas, nausea and change in BM. Since my IBS symptoms began ive never had a chance to test a certain food on my body when its completley empty... (klean prep)The procedure that im having is going to test for celiac disease, i feel that if i havent got that i may have a wheat intolerance, is this something that people have or suffer from?Ive been seriously thinking about converting my diet to Gluten free/Wheat free for a while as i had an idea that it was this kind of food exasperating the IBS (or if i have celiac disease)....What is the difference between a wheat intolerance and Celiac Disease? (difference to what it does to the body and symptoms etc)
