Clinically, the normal value of glutamic oxal transaminase is 0-40U/L. When there is glutamic oxal transaminase 53U/L, it is not considered serious and belongs to slight elevation. The causes of elevation can be divided into physiological and pathological, the details are as follows: 1. Physiological causes: mostly related to the patient’s bad habits, such as excessive exercise, eating too much, taking certain drugs, drinking, staying up all night and so on, can appear a slight elevation of glutamic oxaloacetic aminotransferase. For this situation, we should start from the cause, control the reasonable diet, pay attention to quit alcohol, avoid staying up all night, and the AAT can be gradually returned to normal; 2, pathological causes: high AAT may be the early stage of some diseases, such as alcoholic liver, fatty liver, hepatitis B, viral hepatitis, and other diseases, for alcoholic liver and fatty liver caused by high AAT, we should control the diet, quit smoking, alcohol and other bad habits; for viral hepatitis, we should control the diet, quit smoking, alcohol, and other bad habits; for viral hepatitis, we should control the diet, quit smoking, alcohol and other bad habits; for viral hepatitis, we should control the diet, quit smoking, alcohol, and other bad habits. For viral hepatitis, under the guidance of the physician, anti-viral treatment should be carried out, and drugs such as lamivudine and tenofovir should be taken, and the transaminase can be gradually normalized. Clinically, certain serious diseases can also lead to high AST, such as myocarditis or myocardial infarction, and early lesions should be consulted in time to avoid delaying the condition.
