Chronic lung disease, also known as chronic obstructive pulmonary disease or COPD is now the third leading cause of death, following heart disease and cancer. However, over 48 percent of Americans don't know they have the condition. Left untreated, COPD can worsen dramatically.

Chronic obstructive pulmonary disease is a disorder characterized by persistent obstruction to airflow through the lungs, usually caused by harmful inhaled particles such as those found in tobacco smoke. Yale Medicine through the Chronic Obstructive Pulmonary Disease (COPD) Program is at the forefront of the research to develop more targeted, individualized treatments for patients.
