I'm not sure exactly, only that pancreas was starting to get diseased. I will try and get more info to pass on to you. That's what happened with me. My digestion just kept getting worse. No matter what I did to try and counter it. I finally just gave in and had it out. To me, there is only so much you can take. I felt like I had a ticking time bomb inside of me. Plus I really wanted to get pregnant and couldn't see doing that and having gallbladder trouble. I will try to get that info ASAP.
