There is no definite time for how long patients with cirrhosis in the decompensated stage live, and the life expectancy of patients has a lot to do with the severity of the disease and whether the patient’s mentality is active in the treatment. In the decompensated stage of liver cirrhosis, the main manifestation of liver function is reduced. Generally speaking, the emergence of ascites is the most obvious symptom of decompensated cirrhosis, and the 5-year survival rate of patients after the emergence of ascites is about 50%. In patients with decompensated cirrhosis, life expectancy can usually be prolonged after active treatment of the primary disease and control of complications. If there are conditions to receive liver transplantation, the survival of patients will be greatly improved. Patients with decompensated cirrhosis should maintain a healthy state of mind, establish confidence in overcoming the disease, and avoid staying up late at night. Actively follow the doctor’s instructions for treatment.
