Whether alanine aminotransferase 130 is dangerous or not is related to the cause of its elevation. If the elevation of alanine aminotransferase is caused by physiological reasons such as strenuous exercise, fatigue, alcohol consumption, etc., the elevation can be restored to normal after the removal of the triggering factors, which is generally not dangerous. If the elevation is caused by viral hepatitis, cirrhosis, shock and other pathologic reasons, the condition is more dangerous and requires timely treatment. Alanine aminotransferase is mainly distributed in the liver, and the normal value is 0-40 U/L. Alanine aminotransferase 130 has exceeded the normal value by more than 3 times. Alanine aminotransferase is elevated when the liver cell membrane ruptures, so alanine aminotransferase is generally used as an indicator of liver injury. There are the following reasons for its elevation. 1. Physiological reasons: When alanine aminotransferase is elevated due to liver injury caused by physiological reasons such as strenuous exercise, exertion, alcohol consumption, etc., it can be restored to normal after removing the triggering factors, so it is generally not dangerous. 2. Pathological causes: if alanine aminotransferase is elevated due to acute and chronic viral hepatitis, cirrhosis, shock and other pathological causes, the condition is more dangerous, and even life-threatening in serious cases. There are many other causes of alanine aminotransferase 130, patients should not judge the danger of their condition by themselves, and it is recommended to consult a doctor in time to clarify the cause of the disease and then treat the symptoms to avoid adverse effects.
