Higher alanine aminotransferase may suggest the possibility of liver injury, such as hepatitis, cirrhosis, etc. If it is mildly elevated, generally no special treatment is needed; if it is too high, it needs to receive liver protection treatment and etiological treatment, such as using liver protection drugs such as polyenophosphatidylcholine and anti-hepatitis B virus drugs such as entecavir. 1. Mild elevation: Mild elevation of AST may be due to slight inflammation of the liver, generally it is recommended to pay attention to rest, try to avoid staying up all night, drink less alcohol, and avoid diets, behaviors and medications that harm the liver, which can be recovered after a period of time. 2. Excessive elevation: if the alanine aminotransferase is elevated more than twice, generally the liver has relatively serious lesions, and we need to actively search for the cause of the disease and then target the treatment, which is mainly due to viral hepatitis, cirrhosis, alcoholic hepatitis, drug-induced hepatitis, intra- and extra-hepatic cholestasis, and so on, and it is recommended that the patient should quit drinking alcohol, avoid staying up too late, and use the liver-protecting medicines, such as polyunsaturated phosphatidylcholine, and the anti-Hepatitis B virus medicines such as Entecavir. The patient is advised to quit alcohol, avoid staying up late, and use hepatoprotective drugs such as allylphosphatidylcholine and antiviral drugs such as entecavir. If the test result shows elevated ghrelin, it is recommended to consult a doctor in time to clarify the cause of the disease and carry out targeted treatment or therapy.
