Liver cirrhosis is a kind of lesion caused by the long-term infection of hepatitis virus or long-term alcohol consumption, which can be divided into compensated and decompensated stage, the former can have no obvious symptoms, while the latter will have ascites, splenomegaly, portal hypertension, even esophagogastric fundal vein varicose, and lower albumin, and other manifestations. Liver function tests mainly include transaminase, bilirubin, total protein, albumin and other related indexes, which can be elevated or lowered in cirrhosis, so it can play the role of auxiliary diagnosis, but to make a clear diagnosis, it is necessary to go through imaging tests and liver puncture pathology biopsy. When cirrhosis is detected, it is necessary to consult the hospital in time and receive regular treatment.
