Bronchiectasis and coughing up blood: what to know

Bronchiectasis damages and widens parts of the breathing tubes. Repeated infection, irritation, or forceful coughing can disturb small blood vessels in the airway lining. Blood may appear as streaks mixed with phlegm or as red sputum. The amount, colour, recurrence, and accompanying symptoms help a clinician judge the cause.

Bleeding is not automatically caused by bronchiectasis. Chest infection, pneumonia, tuberculosis, a clot in the lung, and lung cancer are among the problems a clinician may need to consider. A chest examination and sometimes imaging or other tests can help separate these possibilities.

Contact your doctor or respiratory team promptly, even if the bleeding has stopped. Record when it began, whether it was streaking or a larger amount, and whether you also have fever, chest pain, breathlessness, or a change in sputum. Take prescribed bronchiectasis medicines as directed, but do not start leftover antibiotics or stop a blood-thinning medicine without medical advice.

Sit upright, stay calm, and avoid smoking while arranging advice. If you have a written airway-clearance plan, follow it only if your clinician has told you what to do during bleeding.

Call emergency services if bleeding is heavy, continues, returns repeatedly over a short time, or makes breathing difficult. Seek urgent assessment for sudden chest pain, faintness, confusion, blue or grey lips, or a fast worsening of breathlessness. These signs can indicate significant blood loss or a serious lung problem and should not be watched at home.

Ask what may have triggered the bleeding, whether your current medicines affect clotting, and whether you need a chest scan or sputum testing. Clarify which amount or pattern should prompt emergency help and how to adapt airway-clearance exercises until the episode is assessed.
