COPD is already the 3rd leading cause of death globally and in 2019 it accounted for 147,000 deaths in the US, yet 65 to 75% of its burden falls on low and middle income countries where risk can be driven by smoking, biomass smoke, and early life factors. This page connects those causes to what they change in the body and outcomes, from PM2.5 and exacerbation risk to how vaccines, inhaled therapy, and pulmonary rehabilitation can reduce attacks and readmissions.

COPD is still one of the defining chronic threats to lung health, ranking as the 3rd leading cause of death globally in 2019 and taking a heavier toll in low and middle income countries, where 65 to 75% of the global burden occurs. Yet the risk drivers are not uniform, from tobacco and biomass smoke to PM2.5, early life factors, and even occupational exposures. We compiled the key statistics behind that gap so you can see where COPD starts, how it accelerates, and why outcomes can diverge so sharply between groups.

COPD kills millions yearly, heavily affects low income countries, and quitting smoking plus proper care can cut exacerbations.
