Cystic fibrosis is an inherited disease of the mucus glands. It causes chronic, progressive damage to the respiratory system, chronic digestive system problems, and can affect other organs. The signs and symptoms of this disorder are caused by the production of abnormally thick, sticky mucus in the body's organs. Problems with breathing are among the most serious symptoms.
