The normal value of ALT is generally between 0~40U/L. If the patient’s value of ALT is 68U/L, there is a slight increase in the value of ALT, which may be caused by physiological reasons or pathological reasons. 1. Physiological reasons: such as late night, strenuous exercise, excessive alcohol consumption, pregnancy, etc., may cause a transient mild increase in alanine aminotransferase, at this time there is no need for special treatment, by adjusting the work and rest and dietary habits can be restored. 2. Pathological causes: If the alanine aminotransferase continues to rise or rises sharply, it may be caused by viral hepatitis, alcoholic liver disease, fatty liver disease, intra/extrahepatic cholestasis and other pathological causes. At this time, the patient should go to the hospital in time to improve the alanine aminotransferase, bilirubin level and other tests, as well as liver ultrasound, liver CT and other tests to make a comprehensive judgment, to clarify the specific causes of the disease and then carry out targeted treatment.
