Regular drinkers are prone to alcoholic cirrhosis, where the body’s balance is disrupted and they become ill. Similarly, long-term excessive drinking can cause repeated fatty degeneration, necrosis and regeneration of liver cells, eventually leading to liver fibrosis and cirrhosis. According to the progress of alcoholic liver disease we divide alcoholic liver disease into five stages: mild alcoholic liver disease, alcoholic fatty liver, alcoholic hepatitis, alcoholic liver fibrosis and alcoholic cirrhosis. Let’s understand the characteristics of each stage of the development of alcoholic liver disease together. 1.Mild alcoholic liver disease: At this stage, the biochemical, imaging and histopathological examinations of the liver are basically normal or slightly abnormal. 2.Alcoholic fatty liver: At this stage, the diagnosis from imaging meets the criteria of fatty liver, clinical symptoms are mostly mild, jaundice may appear, and glutamic aminotransferase, glutamic oxalacetic aminotransferase, alkaline phosphatase and bilirubin are slightly abnormal. There are varying degrees of hepatomegaly, with liver weight often reaching 2000-2500g, or even 3000g or more (normal 1200-1500g). The liver is yellowish in color with blunt margins. Microscopically most patients have large vesicular lipid changes, which in themselves do not cause perisinusoidal fibrosis, but about 31% have combined mild to moderate hepatic fibrosis. The prognosis is good if the patient adheres to alcohol abstinence, low-fat, high-protein diet supplemented with medication. It has been reported that after 1-4 months of strict abstinence from alcohol, the lipid changes can disappear completely. Alcoholic hepatitis: Alcoholic hepatitis occurs in chronic alcoholics, often with a history of continuous heavy drinking in a short period of time before the onset. Liver failure or hepatic encephalopathy may occur. The characteristic microscopic changes of alcoholic liver disease are hepatocyte necrosis. Alcoholic liver fibrosis: All types of chronic alcoholic liver disease are accompanied by varying degrees of liver fibrosis, and alcoholic liver fibrosis has only been adopted by some scholars as an independent type in the last decade or so. Chronic alcoholism, the direct toxic effects of acetaldehyde on hepatocytes, and by aggravating the metabolic disorders of hepatocytes, cause alcoholic liver disease often form a more unique perisinusoidal fibrosis, terminal venous fibrosis, and the development of lesions can form fibrosis as well as cirrhosis. As a result, alcoholic liver fibrosis can be accompanied by no or only mild alcoholic hepatitis lesions, so it is classified as a separate type of alcoholic liver disease. 5, alcoholic cirrhosis: often occurs in long-term heavy drinkers, early and medium-term alcoholic cirrhosis liver weight of about 1800g, alcoholic cirrhosis is characterized by small nodular cirrhosis, liver enlargement, and its clinical manifestations are similar to those caused by other causes of cirrhosis. It may be accompanied by manifestations of other organ damage due to chronic alcoholism, as well as alcohol-related neuropsychiatric disorders and alcohol withdrawal syndrome. The incidence of alcoholic liver disease has been on a significant upward trend, which also forces us to pay attention to the characteristics of each stage of alcoholic liver disease in order to prevent and properly treat it. The triggering of alcoholic liver disease is largely related to our daily lifestyle, so we should still try to not drink alcohol or drink less to prevent suffering from such diseases and take our own health as a priority.
