Makes sense. I would note that people with celiac are much smaller than the group of people with IBS. For instance, I have a negative celiac test, no bowel inflammation, but do have IBS. And IBS in these cases is often linked to stress.

So while the app is inapplicable to your case, you’re overgeneralizing from your case to all cases.

(I would of course encourage anyone with IBS issues to get a gluten test. It’s important to rule out!)
