Probability of Dying from Chronic Lower Respiratory Disease (COPD)

Chronic lower respiratory diseases, primarily chronic obstructive pulmonary disease (COPD), are the sixth leading cause of death in the United States. The lifetime risk of dying from chronic lower respiratory disease is approximately 1 in 21, according to National Safety Council analysis of CDC mortality data.

Smoking is responsible for approximately 80% of COPD deaths. Other risk factors include occupational dust and chemical exposure, air pollution, genetic factors (alpha-1 antitrypsin deficiency), and a history of frequent childhood respiratory infections. COPD develops slowly over decades, and many people don't realize they have it until it's advanced.

The single most important prevention measure is never smoking or quitting if you currently smoke. At any stage of COPD, quitting smoking slows disease progression. Other measures include avoiding secondhand smoke and air pollutants, getting vaccinated against influenza and pneumonia, and regular exercise to maintain lung function. Early diagnosis through spirometry testing allows for treatments that can improve quality of life and slow progression.
