With the aggravation of the disease, there may be neuropsychiatric symptoms and manifestations such as spider nevus and liver palm. Laboratory tests may show elevated serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), total bilirubin (TBil), prothrombin time (PT) and other indicators. Ultrasound or CT examination of the liver has typical manifestations. Abstinence from alcohol is the most important measure in the treatment of alcoholic liver disease.
