COPD includes emphysema and chronic bronchitis.
Common symptoms include being out of breath during activity and at rest, chronic cough and spitting or coughing up mucus.
COPD is only caused by cigarette smoke.
A combination of medication, pulmonary rehab and oxygen replacement therapy are used for treatment.
Asthma and lung cancer can have similar symptoms to COPD.
Being diagnosed with stage IV, or end-stage COPD, means chances of survival after a year are low.
