Cystic Fibrosis


    Cystic fibrosis is an inherited disease that affects the cells that produce mucus, sweat, and digestive fluid. The affected fluid may then plug up certain tubes and ducts in the body, particularly in the lungs and digestive system. Symptoms vary and can include cough, repeated lung infections, inability to gain weight, and fatty stools. Treatments may ease symptoms and reduce complications.
