Chronic obstructive pulmonary disease (COPD) and asthma are commonly mistaken for one another. They result in similar symptoms, including wheezing, coughing, and trouble breathing. However, the two conditions are quite different.
COPD is an umbrella term used to identify a group of progressive respiratory diseases that include chronic bronchitis and emphysema. These diseases cause reduced airflow due to inflammation in the airways. These conditions may worsen over time too.
