Pathogenesis of alcohol induced liver injury

Fatty change and alcoholic hepatitis are probably reversible. The later stages of fibrosis and cirrhosis tend to be irreversible but can usually be quite well managed for long periods of time.

Fatty change

Main article: Fatty liver

Fatty change, or steatosis is the accumulation of fat in liver cells which can be seen as fatty globules under the microscope. Alcoholism causes large fatty globules (macrovesicular steatosis). Small fatty globules have different causes. Other causes of macrovesicular steatosis include diabetes, obesity and starvation. Alcoholic fatty change is probably dose related.

Alcoholic hepatitis

Main article: Alcoholic hepatitis

Some people get an acute hepatitis or inflammatory reaction to the cells affected by fatty change. This is not directly related to the dose of alcohol. Some people seem more prone to this reaction than others. This is called alcoholic steatonecrosis and the inflammation probably predisposes to liver fibrosis.

Main article: cirrhosis

Cirrhosis is a late stage of liver disease marked by fibrosis and altered liver architecture. It is often progressive and may eventually lead to liver failure. Late complications of cirrhosis or liver failure include portal hypertension, coagulation disorders, ascites and other complications including hepatic encephalopathy and the hepatorenal syndrome.

Cirrhosis also has number of other causes, such as hepatitis and toxins. The late stages of cirrhosis (say from viral hepatitis or alcohol) may look similar. This phenomenon is termed a "final common pathway" for a disease.
