Cystic fibrosis

Cystic fibrosis (CF) is an inherited condition affecting the lungs and digestive system. It is most often diagnosed in newborn babies. 

Our information covers what CF is, the symptoms, treatments, and how it’s inherited. It’s mostly aimed at parents and carers of children who have been diagnosed with CF. But if you have CF, the information is still for you. You can also find out more about living with CF from the Cystic Fibrosis Trust.
