The normal value of AST is 0～40U/L. The causes of AST 119 may include physiological factors, viral hepatitis, cirrhosis, fatty liver, alcoholic liver disease, bile duct disease and even liver cancer. It can be treated by adjusting lifestyle, taking antiviral or hepatoprotective drugs and surgery. 1. Physiological factors: Strenuous exercise, fatigue, heavy drinking and other factors may cause transient hepatocellular damage and transient increase of AST, eliminating these factors, most of the time, AST will recover by itself without medication. 2. Viral hepatitis: Hepatitis B and C usually destroy liver cells and release aminotransferases into the blood. In this case, the main use of antiviral drugs, such as entecavir. Liver protection drugs such as glycyrrhizic acid preparations and bicyclic alcohol can also be used appropriately. 3. Fatty liver: excessive accumulation of fat in liver cells leads to liver damage, and transaminases are released into the blood. Simple fatty liver usually does not need medication, and can be treated by improving lifestyle, such as controlling diet, increasing exercise and so on. 4. Alcoholic Liver Disease: heavy drinking leads to liver damage and transaminases are released into the blood. Abstinence from alcohol is the most important measure, and it can be treated with a combination of liver-protecting drugs such as polyenophosphatidylcholine and reduced glutathione, and hormones such as prednisone can be used when the condition is serious. The elevation of glutamic transaminase is recommended to go to the hospital to clarify the cause of the disease, under the guidance of the doctor to carry out targeted treatment, do not unauthorized use of drugs.
