High transaminases may be caused by liver injury such as viral hepatitis, or due to non-pathologic causes such as late night and exertion. 1. Liver injury is a common cause of transaminases. For example, viral hepatitis, especially hepatitis B virus infection, alcoholic cirrhosis, hepatic cysts, etc. are common liver diseases that cause elevated transaminases. 2. Non-pathologic causes. Non-pathologic causes include living habits and dietary habits. On the one hand, bad habits such as staying up late, overwork, and recent colds can cause transaminase elevation. On the other hand, irrational diet, such as excessive alcohol consumption and irrational dietary structure, may lead to elevated aminotransferases. If the aminotransferase is elevated due to late nights and irregular diet, it is recommended to check again in a few days. If it is still high, it is important to consult a doctor to identify the cause of the disease and then carry out targeted treatment.
