I’m desperate for answers for my 18 yr old daughter's illness. IBS-D / food intolerance. It started around the age of 8. We’ve seen every dr, had every test, tried so many medications. Nothing has worked and all tests always come back normal. She can't eat hardly anything. She is dairy free, gluten free, nut free, she follows FODMAP. She’s allergic to most fruit and some veggies. She has severe flare up episodes, lasting from a few hours up to a week. Does anyone have any suggestions on what else we can try? Geneticists, hypnotherapy, acupuncture? Anything?
