There's a very good website I'd like to recommend. It has questions and answers between PBC patients and doctors. Some of the same questions that some of you have posted on this website. The website is for the Canadian PBC Society.
After going to the site, click on the "research" tab at the top. Click on "Ask a Doc." After reading the questions and answers on this page there is a link to all the previous questions at the bottom. Some of the "previous" questions are very interesting. This is a good way to get information from many doctors treating PBC patients.
Here you go: pbc-society.ca/welcome.html
Hope this is helpful!
