About 20 Years Ago, I Was Diagnosed With Celiac Disease.

About 20 years ago, I was diagnosed with celiac disease. I lost about 60 pounds, and was given creon, and told to avoid gluten. Since then I have been told that I don't have celiac disease, but I still have chronic diarrhea. A recent CT scan for a different issue revealed a calicified pancreas, and stones in the pancreas blocking the ducts. I don't use drugs, and I was never a big drinker. So I'm wondering, what is going on?
