Marco D,
You are correct, it is a long road as it is a chronic condition but don't let the negativity get to you. Positive thoughts really do go a long way when dealign with lifelong conditions. There was nothing you could have done differently. You had mentioned not having done drugs or drinking heavily. PBC has nothing to do with that. I have AIH (autoimmune hepatitis). Same thing, who knows what caused it. Different things could be a trigger but hard to pinpoint one cause. Patients usually have a predisposition where autoimmune diseases are concerned. I have 2 sisters with MS. I, too, am on Urso but to treat a side effect of my immunosuppressant. Generally, Urso is a PBC drug. It's a bile acid to keep the bile thin so it doesn't back up and cause more cirrhosis.
Connie is right, don't think that since it only really came to light now that you have all the time in the world to take action. Be good to your body, eat right, exercise and take your meds. See your doc and get your labs done when you are supposed to. Find out about the alcohol thing. If your doc says none, then none it is! There is a lot of info in Melissa Palmer's book and check out The American Liver Foundation website.
Let us know how you are and welcome to our little liver-related family!
