I was a longtime sufferer of
pancreatitis and have diabetes. You have to try
and normalize your system. Cut out all processed/highly refined foods, do juicing, and small consistent meals. Make your husband quit smoking....it makes the pancreas work too hard.
Since his is chronic, its all about maintenance, and allowing the body to do some healing as well!
If you want I can send you a plan I used which saved my life, and kept me functional. The doctors will just give you meds to ease pain....
