Excessive liver function usually refers to high aminotransferases in the liver, which are sensitive and can reflect the condition and severity of liver damage. An elevation of transaminases above about two times the normal value indicates more serious liver damage. It is most common in viral hepatitis, cholecystitis, pancreatitis, moderate to severe fatty liver, liver tumor and other digestive system diseases. You should do hepatitis A, B, C and other hepatitis series examination and autoimmune hepatitis examination, and do abdominal ultrasound etc. to make a clear diagnosis, and treat the cause, you need to take oral liver protection tablets, glycine and other liver-protecting and enzyme-lowering drugs, if you don’t see improvement, you should be hospitalized. Aminotransferases are affected by many factors, such as eating too much high-fat food, staying up late, drinking a lot of alcohol, being overly tired, mental stress, and strenuous exercise. There are also drug effects, such as antibacterial and chemotherapy drugs, which can also cause a mild increase in transaminases. If this is the case, no medication is needed, as long as the cause is removed, and a light diet, regular life, abstain from alcohol, strengthen exercise, exercise, reduce body weight, avoid taking drugs that damage liver function, etc., most of them can recover on their own.
