• Asthma – thick, white/yellow sputum
• Chronic bronchitis (COPD) – clear/gray sputum
• Pulmonary edema (presence of fluid in lungs) – clear to white, frothy sputum
• Postnasal drip
• Allergic reaction
• Gastroesophageal Reflux Disease or GERD

Cigarette smoking and air pollution can result in the production of grayish phlegm. Clear or white phlegm can also precede the appearance of yellow or green sputum, especially during the early stage of an infection.However,white, frothy sputum may be a sign of health failure, leading to an increase in fluids in the lungs or pulmonary edema.

2. Yellow Sputum

Yellow sputum colour is often seen in infection, chronic inflammation, and allergic conditions. It is due to the white blood cells called eosinphils, which are associated with allergic conditions causingairway hypersensitivity, or neutrophils, which are associated with infection. Examples of conditions when you may have yellow sputum include:

• Acute bronchitis

However, thick, dark-yellow phlegm may indicate a bacterial infection, which may occur in your sinus or lower respiratory tract, such as chronic bronchitis or pneumonia. Seek medical attention immediately.

Green sputum color is an indication of long-standing or chronic infection. It results from the breakdown of the neutrophils, which causes the release of enzymes from the cells.

These conditions may include:

• Pneumonia
• Lung abscess
• Chronic bronchitis
• Cystic fibrosis
