The CF gene was identified in 1989 and this has led to the development of a carrier test, improved treatment and better control of the disease.

At the moment every person who has CF must use intensive daily airway clearance techniques (see physiotherapy) to combat the build-up of mucus in the lungs.  Many people with CF will also take up to 40 enzyme replacement tablets each day to aid digestion (see medication).  They must also follow high energy diets with added vitamins and salt.

Excercise is also a very important part of keeping people with CF healthy as it prevents deterioration of the lungs and improves physical bulk and strength.

Regular visits to CF Clinics, hospitalisation and antibiotic treatment are common for people with CF.
