The survival time of the elderly with pneumonia needs to be decided according to the severity of the disease and the degree of recovery and physical condition of the elderly, which may not affect the life expectancy but can be life-threatening in serious cases. Pneumonia is a respiratory disease. If the pneumonia is mild and the elderly are in good physical condition, after standardized and reasonable treatment, the prognosis is good, and the survival time of the elderly will be the same as that of normal people after recovery. However, if the condition of the elderly is relatively serious and accompanied by other underlying diseases, the prognosis is poorer and the survival time may be greatly reduced. Pneumonia in the elderly may be due to the decline in body resistance or respiratory infections and other causes, it is recommended to actively cooperate with the doctor to clarify the cause of the diagnosis and treatment, usually should always pay attention to warmth, appropriate exercise, regular work and rest, to improve the immune system.
