I don't know much about human medicine, but in dogs, acute pancreatitis can often be caused by a very large, very fatty meal (example: dog got into the garbage and ate a bunch of beef fat trimmed off a steak, or sometimes we see it after Thanksgiving when the pet has been fed excessive table scraps). After the acute episode, they go on a low fat diet to prevent future problems. So I would hazard to guess that a typical fatty diet of lard and sugar is exacerbating the problem. Maybe it'll get to the point where the hospital staff have to put the pig down.
