Cant digest certain things?

ca

Anyone else have this problem? I’ve been having some serious tummy issues, still waiting. On the drs prognoses, and waiting on a colonoscopy soon to find out what’s wrong. I’ve noticed. I can’t digest meat very well, I use to be able too very well. I can only maybe have 1 or 2 chicken nuggets, if I have more, I’ll have serious bloating, and diarrhea. Anyone have any similar issues? Just want to know I’m not the only person out there who’s young with these issues :( 22 here
