Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstruction of lung airflow and interferes with normal breathing. Tobacco smoking is the main cause of COPD. Emphysema and Chronic Bronchitis are the two most common conditions that contribute to COPD.
- Emphysema is a lung disease that occurs when the walls between the alveoli are damaged. The alveoli become larger and air gets trapped in them, which makes it hard to take a deep breath, or to exhale aire from your lungs.
- Chronic Bronchitis is a lung disease that causes the bronchioles (airways) to become swollen and form thick mucus. These changes limit airflow in and out of your lungs, making it hard to breathe.
There is currently no cure for COPD. However, with proper management, most people with COPD can control their symptoms and improve their quality of life.
What are the Symptoms of COPD?
- Shortness of breath, especially with activity
- Chest tightness
- Excessive mucus

When COPD is severe, breathing difficulties can get in the way of basic activities, like doing housework, taking a walk and even bathing and getting dressed. Severe COPD is one of the leading causes of death in the United States.
