Primary Billary Cholangitis.
It's where the bile ducts get blocked, which eventually cause cirrhosis.
More women than men suffer from it, and years ago, it was the main reason people had to have a liver transplant. I think it's changed now, by that I mean, because of the ursodeoxychloric acid medicine and this new drug they're just trialling., whereas, years ago they probably didn't have any treatments for it.
It's not caused by booze, In fact , they don't know why it happens, but they did say, maybe one of my parents MAY have had it, but sadly, couldn't get them tested as they'd already past on.....😢
