What should you know about CF and bronchiectasis?

Cystic fibrosis affects the movement of salt and water across cells, making airway mucus harder to clear. Trapped mucus can encourage infection and inflammation. Over time, airway walls may become widened and less effective at moving mucus; this structural change is bronchiectasis. Bronchiectasis can also have causes unrelated to cystic fibrosis, so the diagnosis and treatment plan should be based on the person’s history and testing.

Follow the airway-clearance routine taught by your CF or respiratory team, including the timing of inhaled medicines if prescribed. Drink fluids as advised, stay current with planned reviews, and record changes in cough, sputum colour, amount, breathlessness or exercise tolerance. A Chest X-Ray may show structural lung changes, while Spirometry helps measure airflow; neither test replaces a full clinical assessment. Antibiotics should be used only according to the treating team’s plan.

Contact your respiratory team promptly for a clear increase in cough or phlegm, new breathlessness, fever, chest pain, reduced activity tolerance or blood in sputum. Seek emergency care for severe breathing difficulty, blue or grey lips, confusion, collapse, or coughing up a large amount of blood. Do not wait for a routine appointment if breathing is deteriorating quickly.

How does my lung function compare with my usual level? Which airway-clearance technique suits me? What sputum changes should trigger a sample or antibiotics, and when should I repeat testing?
