Aminotransferases are one of the important indicators in liver function tests. Normally, aminotransferases are very low in the blood, and high aminotransferases are indicators reflecting the pathological state of the liver, and their danger to the human body depends on the severity of the disease causing the patient’s aminotransferases to rise. If the patient is suffering from hepatocellular destruction and elevated transaminases due to viral hepatitis, the patient may experience general weakness, nausea and vomiting, anorexia and abdominal distention, pain in the liver area and other uncomfortable symptoms, as well as deepening of urine color, yellowing of skin, mucous membranes and sclera, and in severe cases, even coma, irritability, coagulation dysfunction and other manifestations of liver failure, which may even threaten the patient’s life. If the patient is suffering from elevated transaminases due to fatty liver, cirrhosis and other liver diseases, the danger to the human body depends on the severity of the disease, from no discomfort in mild cases to ascites, hypoproteinemia, digestive discomfort and other manifestations in severe cases. If the elevated transaminases are mildly elevated due to medication, fatigue, alcohol consumption, staying up late, fever, etc., it is mostly a transient liver function abnormality, which is less harmful to the human body, and the transaminases will return to normal after the elimination of the above-mentioned adverse factors. In addition, other systemic diseases such as acute myocardial infarction, dermatomyositis, and hyperthyroidism can also lead to elevated transaminases, and the risk to the human body depends on the severity of the primary disease. It is clear from the above that the risk of high aminotransferases cannot be generalized, but depends on the severity of the primary cause of aminotransferase elevation.
