Cystic fibrosis

Cystic fibrosis is a hereditary disease of the mucus and sweat glands. It affects mainly the lungs and pancreas, but it can also affect other parts of the body including the liver, nose and sinuses and reproductive organs. Normally, cells in these parts of the body make mucus and other secretions. Sufferers with cystic fibrosis have cells that do not function correctly, making mucus and secretions thicker than normal.

The symptoms of cystic fibrosis usually develop within the first year of life, but may not appear until later childhood. The severity of symptoms can vary and include:

  • persistent cough which produces a lot of sputum
  • recurring chest infections
  • repeated infections and inflammation can damage the lungs and lead to poor lung function
  • shortness of breath and breathing difficulties
  • wheezing
