What causes the thick bile? What can I do for that. I understand my bile will continue to flow. I don't want to have more problems. My GI doctor didn't explain anything, he just had his assistant set me up with the surgeon. The Surgeon just told me what he was going to do and what time to show up. What can I do to help myself feel better. I'm tired of pain, diarrhea, nausea, feeling feverish.
