- COPD is a disease that interferes with normal breathing. The term covers two main illnesses: emphysema and chronic bronchitis.
- Most people with COPD have a history of smoking.
- Middle-aged and older people tend to develop COPD, developing slowly over time. According to the American College of Allergy, Asthma & Immunology, asthma is more common in children than adults.
