Alanine aminotransferase is one of the most common and important indicators in liver function tests. Patients can reduce alanine aminotransferase by improving lifestyle habits, medication, and treating primary diseases. 1. Improve living habits: If the elevation of alanine aminotransferase is caused by frequent drinking and irrational diet, it is recommended to quit drinking, standardize daily diet and exercise properly, and the alanine aminotransferase may be gradually reduced. 2. Medication: medications that protect the liver or reduce alanine aminotransferase, such as reduced glutathione, diammonium glycyrrhizinate, etc., can be taken under the guidance of a medical professional. 3. Treatment of primary diseases: If alanine aminotransferase elevation is caused by viral hepatitis, biliary obstruction, hepatocellular carcinoma and other diseases, it is necessary to actively treat the primary diseases. Viral hepatitis should be treated with antiviral therapy, and patients with biliary obstruction and hepatocellular carcinoma can be treated with surgery, and alanine aminotransferase may be reduced after active treatment of primary diseases. The above drugs should be used under the guidance of a specialized physician. If abnormal alanine aminotransferase occurs, it is necessary to consult a doctor in time, clarify the cause of the disease and carry out standardized treatment under the guidance of a professional physician, and do not use drugs on your own.
