The liver function indexes of transaminases include ALT and AST, which mainly exist in liver cells and reflect the health of the liver, and are also essential “catalysts” in human metabolism. When liver cells are damaged by inflammation, necrosis, or poisoning, transaminases are released into the bloodstream, causing an increase in serum transaminases. Elevated aminotransferases are only a phenomenon and do not indicate the cause of the elevation, and they are not harmful to the body. Aminotransferase levels between 0 and 70 are normal. If it exceeds the normal range by less than 10 times and there are no obvious clinical symptoms, the doctor will suggest to review the liver function several times without medication for a while to dynamically observe the change of ALT and analyze the cause of ALT elevation. If, after 1 to 3 months of observation, the transaminase level continues to rise and there are positive viral indicators, an appropriate antiviral treatment program can be considered. Treatment of hepatitis B is completely possible without enzyme-lowering drugs. If it is caused by toxic factors such as drugs and alcohol, the treatment is based on treatment to reduce the burden on the liver, detoxify the liver and promote liver cell repair. If the elevated ALT is caused by immune dysfunction, then immunomodulatory treatment is the main treatment. In short, do not worry too much about the elevation of ALT and directly add simple enzyme-lowering drugs such as Wu Wei Zi and Baxinol. Because the effect of such enzyme-lowering drugs is to play a rapid cleavage effect on transaminases, not transaminases really do not exist, not to mention the reduction of liver inflammatory activity and the improvement of the disease, but rather mask the truth of the disease. Only when the physician understands the cause of the disease and gives proper treatment from the root, while making ALT gradually return to normal, is it safe and reliable. Only then can we achieve our goal of liver preservation. However, if the value of transaminase rises to >2000UI/ml, i.e. more than ten times the normal value, or even dozens of times, especially when accompanied by obvious symptoms such as weakness and poor performance, it is necessary to pay high attention to it, and immediately go to a specialized hospital to receive standardized treatment, so as to control the deterioration of the disease as early as possible, so as to avoid missing the “golden window” of treatment. In order to avoid missing the “golden window” of treatment and causing unnecessary human and material losses.
