About COPD

What is COPD?

Chronic obstructive pulmonary disease (COPD) is one of the most common lung diseases. It makes it difficult to breathe. There are two main forms of COPD:

• Chronic bronchitis, which involves a long-term cough with mucus
• Emphysema, which involves destruction of the lungs over time

Most people with COPD have a combination of both conditions.
