How long can he survive?

“We know NOT the Day, Nor the Hour.......”

My mom has liver failure and she is at 97 days without food but drinks lots of water. It’s incredibly baffling. Every doctor or nurse or specialist I talk to just says “wow”. I wish I could understand.

I would try getting him to drink some nutritional drinks such as ensure.

Surprisingly, quite a long time. Even minimal amount of fluid alone can see a person living for more than a month. Do you have hospice working with you? Wish we could tell you more. If hospice is there they will be able to make a more full individual assessment, but no matter how medical community tries to guess, they often get it wrong. So sorry. This must be so very hard for you.

Quite a while, I'd say. His biggest issue would be dehydration, but he certainly isn't burning a lot of calories.
