The life expectancy of a person diagnosed with chronic obstructive pulmonary disease or COPD cannot be predicted, although COPD is a progressive lung disease that shortens overall lifespan, states Healthline. Several factors such as overall health status and coexisting health conditions determine the lifespan of a person with COPD.
The progression of COPD is slowed by stopping smoking and avoiding secondhand smoke and other irritants such as chemical dust and air pollution. Additionally, learning how to improve breathing by using exercises such as pursed-lip breathing slows progression of the disease. Maintaining a healthy weight with good nutrition and eating frequent meals to maintain weight are also helpful for improving life expectancy when living with COPD, explains Healthline.
