It is known that 10 % liver function is compatible with life.
However, if this person has already reached the limit, then he has no reserves left. He is vulnerable to develop lver failure in the event of stress.
This fellow is better adviced to keep away from alcohol, high protein diet.
The liver has a wonderful capacity to regenerate but the scarring in cirrhosis prevents regeneration. He may loose the present function if he does not quit drinking. If he continues to drink , there is less than 50 % 5 year survival.
The deaths due to cirrhosis are due to complications. The complications become less likely eith abstinence & early medical care. Also the morbidity decrease with abstinence.
This is not a question of how much the risk decrease on stopping alcohol intake. This is a chance to improve probability of survival. The benefit is priceless-- a chance to longer & better life. percentages dont count.
Why not enroll him with Alcoholic anonymous/ detox program.
