Judging from the posts you put in other communities, it sounds like he has cirrhosis from alcohol abuse. There is a medhelp community called 'cirrhosis of the liver' (you'll see it on the right hand side of this page). I am quite sure there are some knowledgable members there who can help you better. Good luck.
BTW, liver diseases often times have no symptoms, so a person usually "feels healthy" until the liver is decompensated.
