Liver failure belongs to the most important symptoms of liver disease, which can be divided into acute liver failure, subacute liver failure and chronic liver failure. The survival time of the organism is related to the type of liver failure, and there is no uniform conclusion about the specific time. 1. Acute liver failure: due to the cause of short-term necrosis of a large area of the liver, so the patient’s survival period is often relatively short, prone to coma symptoms, coupled with diarrhea as a complication, may lead to short-term death of the patient. 2. Subacute liver failure: it is easy to lead to severe damage to the patient’s liver, a short period of time to produce more serious clinical syndromes, coupled with diarrhea, it is easy to lead to the patient is likely to die in one or two months. 3. Chronic liver failure: patients with chronic liver failure may reach a longer survival time, such as 1 year, 3 years or even 5 years, and if liver transplantation can be carried out in time, they may also get a longer survival time, such as 10 years or 20 years. Therefore, liver failure is a more serious disease and patients need to actively receive treatment to prolong their life. Early detection and timely treatment of patients can control the progress of the disease and prolong the survival of patients. If not treated in time, resulting in continued deterioration of liver function to develop into advanced stage, the disease death rate is higher.
