About cystic fibrosis
Cystic fibrosis (CF) is a genetic condition affecting over 11,000 people in the UK. You are born with CF and cannot catch it later in life, but one in 25 of us carries the faulty gene that causes it, usually without knowing.
CF: It's complicated
Join us this CF Week, 8–14 June, and help shine a light on the daily realities of living with CF.
Current issues
Find out about plans to reform Personal Independence Payments (PIP), energy costs, Creon shortages, what we're doing to help resolve these issues, and how we can support you.
CF never lets you have a day off
Cystic fibrosis is a life-limiting, genetic condition without a cure. It dominates thousands of lives every day. You never get a day off when you have CF.
