In life, many people consult me about the liver biochemical examination report card, patients by other disease examination found that their liver function is not normal, it is very nervous, of course, any abnormality in the eyes of the doctor can not be ignored. If a weekday a very healthy adult physical examination found abnormal liver function, the first thing to consider is whether there is viral hepatitis, such as hepatitis B, hepatitis C, etc., and secondly, there is no overweight, there is no regular consumption of alcohol, etc. caused by fatty liver. If there is a basic disease of the elderly, consider the above diseases on the basis of whether there is autoimmune liver disease, infection toxic liver disease, multiple organ failure, there is the most important type of disease is drug liver injury, as the saying goes, medicine is three times poisonous, any drug is basically detoxification through the liver, renal excretion. If infants and young children with liver dysfunction in addition to the above epidemics, the most important thing to consider is whether it is related to infection, hemolysis and other uncommon viral infections, infants and young children with liver injury in genetic metabolic diseases is not uncommon, usually in the provincial hospitals to confirm the diagnosis of liver structure congenital developmental anomalies can also cause varying degrees of liver injury, and the prognosis is not the same. Of course, the causes of liver damage can’t be summarized in one or two sentences, and there are several books on various liver disease guidelines developed by experts, so it would be a joke to figure out the causes of liver damage with just a few words from me. Anyway, after liver damage occurs, the key is to actively search for the cause of the disease on the basis of liver protection to reduce liver damage, and then actively treat the cause of the disease, so that it is possible to do once and for all. Finally, remind Oh, weekday protection of the liver is very important, in addition to avoid excessive intake of drugs that harm the liver, be sure not to abuse alcohol, moderate drinking will not increase the burden on the liver, patients with liver disease must quit drinking, overweight friends, we must lose weight Oh.
