What is the life expectancy of non alcoholic cirrhosis of the liver early in stage 4?

Depends: On many clinical factors. Could be decades but if signs of liver failure could be much shorter. Get follow up with a gastroenterologist or hepatologist.

Depends: Today the term "cirrhosis", which was once a death sentence, is becoming unfashionable even among us pathologists as it overlooks how remarkably well many livers heal when the underlying cause (if identifiable) can be discovered. I can't give you a number, but i can give you a stronger hope that perhaps you've found in your reading. Good luck.
