I was diagnosed with IBS 15 years ago which has steadily got worse over the years to the point I’m in pain every day. I suspected gluten and had a blood test for coeliacs which was negative however my gp advised trying gluten free for a while to see what happened. I ignored this a long time but recently gave it a proper go. After just over a week gluten free I felt amazing! No pain, no bloating normal bowel movements however last night after another gluten free meal I had another ‘attack’ pain, diarrhoea and bloating with hangover type feelings today. I feel back to square one 😔 could I be wrong and it not gluten at all or can this happen?
