Cystic fibrosis is a genetic condition that causes the body to produce unusually thick, sticky mucus, primarily affecting the lungs and digestive system. It leads to recurrent chest infections, breathing difficulties, and problems with digesting food and absorbing nutrients.

01 · Know
What is Cystic Fibrosis?
Cystic fibrosis is a genetic condition that causes the body to produce unusually thick, sticky mucus, primarily affecting the lungs and digestive system. It leads to recurrent chest infections, breathing difficulties, and problems with digesting food and absorbing nutrients.
It's identified through newborn heel prick screening, allowing treatment to start early. While there's no cure, significant advances in treatment, including newer medications targeting the underlying genetic defect, have dramatically improved both quality of life and life expectancy for people with cystic fibrosis.
02 · Understand
Clinical context
Newer treatments target the underlying cause, not just symptoms
A newer class of medications, called CFTR modulators, work by targeting the underlying genetic defect in cystic fibrosis, rather than just managing symptoms, and have significantly improved outcomes for eligible patients.

When to Contact Your Specialist Team
- 1You notice a change in your usual symptoms, such as increased cough or mucus
- 2You have signs of a chest infection, which need prompt treatment in cystic fibrosis
- 3You have questions about your treatment plan, including newer medications
- 4You're experiencing digestive symptoms or difficulty maintaining your weight

Practical steps
Chest Infections Need Prompt Treatment in Cystic Fibrosis
Because of the thick mucus associated with cystic fibrosis, chest infections can progress more seriously than in the general population — contact your specialist team promptly for any signs of infection.
- 1Follow your airway clearance routine consistently.Physiotherapy techniques to clear mucus from the lungs are a core part of daily management.
- 2Take all prescribed medications as directed.This may include enzyme supplements for digestion, antibiotics, and, if eligible, CFTR modulator therapy.
- 3Attend regular specialist clinic appointments.Cystic fibrosis is managed by a specialist multidisciplinary team monitoring lung function, nutrition, and overall health.
- 4Maintain good nutrition.A dietitian can help address the specific nutritional needs associated with cystic fibrosis.
- 5Seek prompt treatment for chest infections.Early treatment helps protect long-term lung function.
