What causes green and thick phlegm?

Green, thick phlegm may be caused by diseases such as bronchitis, pneumonia, or lung abscess. It is important to seek medical attention and receive treatment under a doctor's guidance based on the underlying cause. Specific details are as follows:

1. Bronchitis

When the bronchi are stimulated by external factors leading to infection with mycoplasma or chlamydia, symptoms may progress from dry cough to producing thick, green mucus. It is recommended to follow medical advice and use antibiotic medications such as cephalosporins, amoxicillin, or penicillin for anti-infective treatment.

2. Pneumonia

When the lungs are infected by bacteria such as Staphylococcus aureus or Streptococcus pneumoniae, repeated inflammatory stimulation can also result in coughing up thick green sputum. Under medical guidance, medications such as cefixime, levofloxacin tablets, or moxifloxacin may be used to relieve symptoms.

3. Lung Abscess

When the lung develops a purulent inflammation due to infection by Pseudomonas aeruginosa, it may lead to coughing up green pus-like clumps in the sputum. It is recommended to follow medical advice for postural drainage or bronchoscopic lavage to remove the pus.

In addition, green, thick phlegm may also occur in patients with chronic obstructive pulmonary disease (COPD). It is advisable to seek timely medical evaluation at a hospital to determine the exact cause and receive appropriate, targeted treatment.
