Chronic Obstructive Pulmonary Disorder (COPD) refers to a group of diseases that cause airflow blockage and breathing-related problems, including emphysema and chronic bronchitis. Symptoms of COPD include frequent coughing or wheezing, excess phlegm, mucus, or sputum production, shortness of breath, and/or trouble taking a deep breath.¹ In 2020, 12.5 million Americans—5.0% of adults in the United States—reported a diagnosis of COPD, chronic bronchitis, or emphysema, though this is likely underreported. According to 2010 data, 8.5 million adults reported a diagnosis, but more than 18 million Americans had evidence of impaired lung function consistent with COPD.² In 2020, 148,512 people died from COPD, making it the sixth overall leading cause of death in the United States.
