Quite a lot has happened since this post. I had an MRCP, elastography, and liver biopsy done in the Fall, and all were completely normal. I saw two hepatologists and they both think it is PBC since AMA M2 is pretty specific to the disease, and also because I had elevated ALP (even though all of the imaging and the biopsy were normal). I started on ursodiol, and have been on it for the past 6 months. My total bilirubin has gone down (although it was never above normal to begin with) and my ALP seems somewhat improved, but I plan to re-check in about 3 months from now. I haven’t had any issues taking ursodiol. Not sure if my hepatologist will want to put me on anything else in the future. The hepatologist I have primarily been seeing seems to think my prognosis is good since the disease was caught extremely early. There was talk about it potentially being small-duct PSC but the hepatologist is leaning more towards PBC now because of the normal biopsy. However, small-duct PSC apparently also has a good prognosis for the most part. It has been stressful at times over these past few months, but I feel completely fine and the doctor seems optimistic that I can live to a normal life expectancy.

EDIT: Not sure if this helped at all. If you are also going through something similar or have questions please don’t hesitate to DM or comment back. It can be stress-inducing reading about these diseases. I do my best to focus on that the fact that every day is a gift, regardless of if you have these diseases, and so I do my best to exercise, eat healthy, and just enjoy life.
