Alanine aminotransferase 112 U/L is above the upper limit of normal values and can be treated with medications and surgery. Alanine aminotransferase, which is mainly found in liver cells, has a normal value of 0-40 u/L. When liver cells are destroyed in liver injury, the level of aminotransferase in the blood rises significantly. The common causes of elevated alanine aminotransferase include acute and chronic viral hepatitis, non-viral liver disease, intra- and extra-hepatic cholestasis, and so on. 1. Acute and chronic viral hepatitis: patients need to rest, avoid exertion, eat easily digestible food rich in vitamins; medication commonly includes hepatoprotective drugs such as reduced glutathione, antiviral therapy such as interferon. Note that different types of hepatitis have different indications for antiviral treatment, and it is recommended to go to hospital for standardized treatment. 2. Non-viral liver disease: first of all, it is necessary to get rid of the cause of disease, such as alcoholic hepatitis, drug-induced hepatitis need to stop using the drug that induces the disease and quit drinking, and steatohepatitis need to reduce weight and quit drinking; medication is often chosen as liver-protecting drugs, such as polyunsaturated phosphatidylcholine; hepatocellular carcinoma patients can choose surgical treatment and chemotherapy according to the different conditions of the disease. 3. Intra-hepatic and extra-hepatic cholestasis: Surgical treatment should be carried out according to the different obstruction sites after the cause of the disease is clarified, and anti-infective drugs such as metronidazole should be chosen according to the condition. Patients with elevated alanine aminotransferase are recommended to go to the hospital in time, after a clear diagnosis, according to the cause of the disease to choose the appropriate treatment program, do not blindly self-medication.
