Cystic fibrosis (CF) is a genetic condition affecting more than 10,900 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. Our Helpline is available to anyone looking for information or support with any aspect of cystic fibrosis, a listening ear, or just to talk things through. Our friendly team are here if you need us.
