This won't answer your question, but I've been reading a lot about pancreatitis, and while there are some known causes, i.e alcoholism, often there is no cause (or one that can be identified). You likely are just one of those lucky folks, as you said. I think you have to be a serious alcohol drinker to blame that, otherwise there would be a lot more people with pancreatitis walking around!

I'm curious about your enzyme levels, which are elevated. Is that typical of pancreatitis? That they are elevated, not low? I suppose I could look into that....
