Survival time for pulmonary fibrosis over the age of 65 varies from person to person, and is largely related to the severity of the condition. In the case of mild pulmonary fibrosis, there is often no impact on life expectancy, and in the case of more severe pulmonary fibrosis, survival time may be only a few years. Pulmonary fibrosis is a kind of lung disease that cannot be completely cured. Pulmonary fibrosis patients have significant lung tissue damage, which affects lung function, and when it progresses to pulmonary hypertension or even pulmonary heart disease, the survival life of the patient will be greatly reduced. Patients with pulmonary fibrosis should maintain a healthy lifestyle, quit smoking, and should often open windows and ventilate their homes to prevent respiratory infections. Regularly go to the hospital for examination, and use some anti-fibrosis drugs under the guidance of the doctor.
