Hepatitis is inflammation or swelling of the liver. Alcoholic hepatitis is swelling of the liver that is caused by drinking alcohol. In most cases, alcoholic hepatitis is the result of years of heavy drinking.
But the relationship between how much alcohol is consumed and whether a particular person has alcoholic hepatitis is not clear, so some people who only drink moderately can also develop alcoholic hepatitis.
Alcoholic hepatitis is a condition that develops over time. The longer you drink, the more likely you are to develop liver inflammation. This can have serious consequences.
