I was diagnosed with IBS 15 years ago yet been unable to get on top of it, it’s gradually got worse. I decided to try an elimination diet and realised I can’t tolerate onions. I test negative for coeliacs but in desperation decided to try cutting it out for a while, it’s been 4 months now. My IBS is 95% better, I’m no longer in constant pain or bloated, however I am exhausted and weak. I want to try and reintroduce again to test things out but I’m not sure the best way to do it. Is it likely I will experience side effects purely for being off it for a while? Or if I do get side effects will this be conclusive that I can’t tolerate it? I’m confused that my stomach feels so different yet I tested negative for coeliac. Has anyone done something similar?
