I seem to be in the minority of those who don’t. I also have other mental stuff leading to extra anxiety/stress… yet have never been prone to GI issues, ever in my life. Probably at least in part because I’m paranoid about food safety, it’s rare for me to even get a “stomach bug”, I’ve had exactly two bad ones in… wow, I think 15 years
No food sensitivities or intolerances to the best of my knowledge, either. Extraordinarily merciful, since I have an extreme aversion to significant GI ailments (as in, I would rather die than have diarrhea - that one’s the strongest), but I suppose I would probably have gotten used to it if I didn’t have such a hardy system. Can’t bear the thought of having diverticulosis or something like that either.
My NT brother has severe Chron’s disease that came on suddenly around two years ago, my NT mother is prone to GI problems.
