I ride horses and have taken more than one spill from their backs. You fall, and hopefully don't pop the pouch, lol. As far as taking a direct hit, I imagine your stoma will bleed (they bleed very easily), but I can't imagine much damage, at least no more than if you didn't have one.
That's the beauty of an ostomy for me, I can finally do all the things I couldn't do for years.
25+years diagnosed with CD.
Numerous surgeries, permanent ostomy, adverse reactions to Remicade, still on Prednisone (my worst enemy), Finally had another surgery hoping for a long remission.
