What is Cystic Fibrosis?

Cystic Fibrosis (CF) is a condition in which there is an abnormality in the way sodium and chloride (salts) pass through some of the cells in the body. This results in some of the normal secretions or mucus in the body being ‘thick and sticky’, rather than thin and fluid.

Children and adults with CF have particular difficulty clearing sticky mucus in the lungs and are more likely to pick up chest infections. This same sticky mucus prevents the chemicals in the body that help digest food (pancreatic enzymes) from reaching the small bowel. These enzymes are needed to digest and absorb food (especially fats) in order to grow and thrive
