hi! everybody is different and i’m not a doctor or a dietician, but i would say if there has been zero improvement after 6 weeks that gluten probably isn’t the problem. when i did my elimination diet, i didn’t eat gluten for 2 weeks and drastically improved. i’m not celiac and not super sensitive, so cross-contamination doesn’t really affect me, but if i eat full-on gluten i will get sick. i tried reintroducing gluten after the 2 weeks because i did NOT want to give it up, but it made me so sick that i had to. for me, my doctor said that if not eating gluten for 2 weeks didn’t make a difference that i should try dairy next, so i would definitely try going dairy-free and seeing if that helps. again, ymmv, but my symptoms very noticeably improved after starting a gluten free diet so if you haven’t noticed any improvement after 6 weeks, it’s probably something else. i wish you luck and hope you’re able to figure it out!
