Foamy sputum is a respiratory symptom in which a person produces a wet, frothy substance from their mouth or nose when they cough. It is usually caused by an accumulation of mucus and air in the lungs. The sputum may be clear, white, yellow, or green, and may contain pus or blood. It can be a sign of a wide variety of conditions, including bacterial or viral infections, asthma, COPD, and pneumonia. Foamy sputum typically develops over time, increasing in amount and viscosity as the underlying condition progresses.
