IBS from refeeding syndrome?

I did my first longer fast (3.5 days) a month ago. I was careful on the first evening re feed (started with broth, then some fish etc). But i didn’t follow the rule to re feed for half the time of the fast, and after half day ate some regular foods.

Well I sure paid the price. Had the worst diarrhea ever for the rest of the day. I swear by bedtime it was stomach acid coming out my ass because it burned like hell. I was exhausted and kind of just collapsed into bed hoping to get enough break from it to sleep.

Anyways, seems like since then every time I eat I have loose stools. If I eat a big meal (like on an Omad day), I get diarrhea a couple of hours later and liquid poop.

Has anyone else had this issue? Thanks in advance

Answer

I’ve had something similar happen. It can be chemicals within the food or the food itself. I wouldnt be super worried, just maybe don’t eat some of those items in the future at the same point, except in very modest amounts.

Answer

Thanks everyone for your replies. I am going to try eliminating things from diet to see if that helps (like dairy). Just so weird that it has been since the fast like it made me more sensitive or something.

Answer

Sorry I should clarify - I get diarrhea every day I eat now (I eat during 3-6 hour window), a couple of hours after I eat (one round of it every day pretty much). Ever since that refeeding a month ago.
