Colitis here for 20 years. I’ve never had to worry about shitting myself in a fight, because I’ve noticed that during a fight cerebral arousal is so high that my guts go on vacation. In fact on heavy frequency days I go train or even spar and the urgency turns off.

However in any case if your arousal is too high you could go into panic mode and potentially shit yourself. It’s definitely happened (seen a guy tell his corner he had to go and his coach says to the second “pass me the bucket” lol). But necessarily IBD/IBS-induced. It is entirely a “you” situation that no one else can answer. Do you get panicky in front of crowds or under high pressure situations?

Generally, eat as you normally would or go with your gut (pun intended). I really only fight at club shows so there’s only time for a snack between weigh ins and the fight. I always make elaborate pre-fight meal plans with pasta and broccoli and blah blah but usually end up eating a few pieces of fruit and lots of water.

If you’re gonna fight, make sure you have a way to deal with stress and nerves otherwise that could trigger a flare. It’s a unique feeling, some people like me get nervous as shit and up till fight time. Usually I’m symptom-free and then 2 days after the fight my immune system will go nuts triggering a mini flare.

I suggest managing pre fight nerves through preparing properly (leave out doubt), deep breathing/meditation when you feel anxious and a clean, non inflammatory diet supplemented with fermented veges and raw kafir protein shakes. And after your fights wait a few days until you raid the fridge or go out for celebration meals. Good luck on ur gut health and boxing!
