A transaminase of 100 U/L is considered a mild elevation of transaminases, and the common causes are non-disease and disease factors. Non-disease factors can be cured by themselves, but whether the transaminase elevation caused by disease can be cured by themselves is related to the cause of the disease. 1. Non-disease factors: irregular work and rest, strenuous exercise, etc. can lead to mild elevation of aminotransferases, which can be cured by adjusting work and rest. 2. Disease factors: including viral hepatitis, alcoholic hepatitis, drug hepatitis and so on. (1) Viral hepatitis: Hepatitis A and Hepatitis E are self-limiting diseases, which can be cured by themselves; Hepatitis B and Hepatitis C are difficult to be cured by themselves, which need to be treated with hepatoprotective therapy. (2) Alcoholic hepatitis: the general prognosis is good. Most of them can be recovered if timely treatment and alcohol cessation are available. (3) Drug hepatitis: most patients can recover after stopping drugs in time; the prognosis of those with serious liver injury is poorer and difficult to recover. If you find transaminase rising, you should go to the hospital in time to clarify the cause of the disease and follow the doctor’s advice.
