Hepatitis B cirrhosis decompensated stage how long can live, is to be judged according to the patient’s condition, the specific how long can live can not be given a specific length of time. Hepatitis B cirrhosis uncompensated stage may have more serious complications, such as gastrointestinal bleeding and other diseases. Because in the decompensated stage of cirrhosis, the liver will be gradually damaged, the function will continue to decline, so the emergence of complications is very common phenomenon. When complications occur, if they are severe, it is unlikely that they will be fully cured. However, if the disease is effectively controlled in time, it is possible to prolong the life span, and it is impossible to give a specific length of time for how long one can live. After entering the decompensated stage of hepatitis B cirrhosis, antiviral treatment should be carried out, which can slow down the time of damage. The duration of life after entering the decompensated phase is significantly related to the level of medical care, the patient’s own health, and the state of the underlying liver. For patients with cirrhosis, it is important to prevent complications in advance, standardize diagnosis and treatment under the guidance of a doctor, not to overwork, and usually eat more nutritious food in the diet to improve liver function.
