15 COPD Symptoms
Coughing up phlegm (also known as sputum or mucus) is a common symptom of COPD.
Even healthy people produce mucus to keep the airways moist. But in COPD, too much mucus is produced, and it can act like a spider’s web, trapping smoke, bacteria, or other particles that would normally be expelled.
Clear-colored sputum is most common, but sputum that turns deep yellow, green, brown, or red or is blood-tinged probably could mean that the lungs have an infection.
