The life expectancy of patients with silicosis pulmonary fibrosis cannot be generalized. Those with mild lesions and active treatment may survive for a long time like healthy people; those with severe lesions and no active treatment may die within a few days. 1. For those with mild lesions and active treatment: if the area of pulmonary fibrosis lesions is small and relatively limited, patients can survive for a long time after active anti-infection and anti-fibrosis treatment, such as using azithromycin, pirfenidone, etc., and keeping away from smoke and dust pollution, and the condition is under good control. 2. Those with serious lesions and no active treatment: If the lungs are fibrotic over a large area, the lung ventilation and exchange function is seriously impaired, combined with dyspnea, respiratory failure, etc., the serious cases may die of respiratory failure in a short period of time. Silicosis pulmonary fibrosis patients are recommended to stay away from smoke and dust stimulation, do a good job of personal protection, go to the hospital in a timely manner, under the guidance of the doctor’s active treatment.
