Frankly speaking, in the early stage of liver dysfunction, most of the existing liver function tests or laboratory indicators do not reflect the true and full function of the liver. As already mentioned, there are many liver functions, which are very complicated, and it is impossible and unnecessary for us to figure out all of the above liver functions in every patient, especially in the early stage of liver disease, when we focus on understanding the cause of the disease and frequent follow-up of a few indicators. The liver function indicators that are often used for long-term observation are transaminases, bilirubin, albumin, alkaline phosphatase, gamma-glutamyl transpeptidase and so on. In more severe liver disease, the patient’s history and other information, such as a history of liver disease for many years, repeated elevations in transaminases, the patient’s dull complexion, abnormalities found on ultrasound or other imaging studies, etc., can often determine that the patient may have severe liver dysfunction. If a patient with liver disease is unable to maintain normal levels of albumin despite being able to eat, serum bilirubin remains high, prothrombin time is significantly prolonged, accompanied by swelling, ascites, esophagogastric fundic varices, leukocyte and platelet reduction, etc., the doctor can determine that the patient has already lost liver function, which unfortunately is already in the advanced stage of liver disease. So at the present time, for a patient with early stage liver disease, it is never just about how the liver function status is, what we need to know is whether this patient has liver disease, whether there is liver damage, and the exact cause of liver damage, and then we need to work together with the patient to treat the cause (because allopathic treatment especially needs the patient’s cooperation), and even if we can’t treat the cause, we need to take measures such as liver preservation treatment, and we need to find ways to protect We should try to protect liver cells from further damage and prevent the development of intermediate and advanced liver disease, including liver fibrosis, cirrhosis and liver cancer.
