Cystic fibrosis is an inherited condition that causes sticky mucus to build up in the lungs and digestive system. This causes lung infections and problems with digesting food.
In the UK, most cases of cystic fibrosis are picked up at birth using the newborn screening heel prick test.
Symptoms usually start in early childhood and vary from child to child with progression over time, although diagnosis can be made later in life
Treatments are available to help tackle the problems caused by the condition and make it easier to live with, with some new treatment developments and ongoing research helping to continue to improve outcomes.
