Cirrhosis is typed into compensated and decompensated stages, with advanced and decompensated stages being overlapping concepts. By the decompensated stage, which is the end stage of the liver, the middle and late stages of liver disease are also known as the late decompensated stage. The compensated stage is when the liver itself can compensate, because the liver is very good at compensating. Scientific experiments have shown that the extreme liver resection in healthy humans can cut to 70%-80% of the original liver, and the compensatory phase lasts longer in cirrhosis. Loss of compensation means that the remaining liver cells of the liver, has not been able to meet the normal needs of the body. For example, the original relies on the liver to produce albumin, now the remaining liver cells, albumin production is not enough to meet the normal needs of the liver and the body, there will be symptoms such as ascites, called the decompensation stage. The signs of the decompensated stage are complications such as ascites, upper gastrointestinal bleeding, and hepatic encephalopathy, which require careful treatment. The aim of treatment for cirrhosis is to prolong the compensated phase as much as possible and delay the time to enter the decompensated phase.
