Alcohol can damage liver cells. Changes in the liver after 1 year of abstinence from alcohol are improvement in aminotransferases, reduction in hepatitis and other liver diseases, and improvement in anemia. 1. Transaminases in the liver usually recover gradually after 4 weeks of abstinence from alcohol, and if there is no other underlying disease, liver function will basically return to normal after 1 year of abstinence from alcohol. 2. If you are suffering from hepatitis, cirrhosis and other diseases, abstaining from alcohol will also improve the condition of hepatitis, cirrhosis and other liver diseases. 3. Abstaining from alcohol can improve the absorption and metabolism of nutrition, and then the symptoms of wasting and anemia will be significantly improved. It should be noted that, if the patient has reached the decompensated stage of liver cirrhosis due to long-term alcohol abuse and has symptoms such as splenomegaly, ascites, gastrointestinal bleeding, etc., the patient cannot be improved by alcohol cessation and needs to undergo systematic treatment in the hospital.
