What is COPD?
COPD stands for chronic obstructive pulmonary disease. COPD is a long-term lung disease often caused by smoking.
COPD includes chronic bronchitis and emphysema. Many people with COPD have both bronchitis and emphysema.
What does COPD do to my lungs?
COPD slowly damages your airways, the breathing tubes that carry air in and out of your lungs. COPD makes airways swollen and partly blocked by mucus. It also damages in the tiny air sacs at the tips of your airways. This makes it hard to move air in and out of your lungs.
What are the symptoms of COPD?
The main symptoms of COPD are a long-lasting cough, coughing up mucus, and being short of breath. Learn more about COPD symptoms >
How do doctors diagnose COPD?
