Chronic obstructive pulmonary disease, or COPD, is a serious lung disease that makes it more difficult to breathe over time. If COPD remains untreated, the disease can have serious effects on a person’s everyday activities. Many times, symptoms of the disease are brushed off as a sign of aging or being physically inactive. But COPD is the third leading cause of death in United States. The disease kills more than 120,000 Americans each year, or one person every four minutes.
