If he has EPI he is not getting any nourishment from his food no matter how much you feed him, he needs enzyme replacement therapy like Viokase.
Please go over to this group, lots of good info and knowledgeable members about EPI. Forum - EPI * Exocrine Pancreatic Insufficiency
Good luck, I hope he gets better and you can figure out what is going on
