What happens if bronchiectasis is not treated?

Bronchiectasis widens and scars parts of the airways, so mucus may collect instead of being cleared effectively. Stagnant mucus can support infection, leading to recurring flare-ups with cough, coughing up phlegm, tiredness, fever or increased shortness of breath. Repeated inflammation may reduce exercise tolerance and make airway clearance more difficult. Some people also cough up blood. The pattern varies, but a change from your usual sputum, breathing or energy level deserves attention rather than being ignored.

Arrange medical review if you have a long-lasting productive cough, repeated chest infections or breathlessness. A clinician may use a Chest X-Ray and Spirometry alongside your history and examination to understand the lungs and airflow. Your plan may include airway-clearance techniques, treatment for infections when needed, and support for activity and breathing. Drink fluids as advised and follow any demonstrated airway-clearance routine; seek individual guidance if coughing brings up blood.

Get urgent help for significant or increasing coughing up blood, severe breathlessness at rest, blue or grey lips, chest pain, confusion or inability to speak in full sentences. Prompt review is also needed when fever, phlegm colour or volume, or breathing is clearly worse than your usual pattern.

Ask how to recognise a flare-up, which airway-clearance method suits you, when testing is needed, and what amount of blood or breathlessness should trigger urgent care.
