How long can a hepatitis patient live?

Not predictable. One cannot tell how long a hepatitis patient will live because there are different kinds of hepatitis, with different levels of severity. For example, if a person gets hepatitis a, there is no reason to believe he will have a change in his expected lifespan from it. Hep a usually goes away in a few weeks, and the person is ok again. However, a very unlucky patient can die during his hep a illness.
