What is Cystic Fibrosis?

cfbubblesCystic fibrosis is an inherited chronic disease that affects the lungs and digestive system of about 30,000 children and adults in the United States (70,000 worldwide).

A defective gene and its protein cause the body to produce thick, sticky mucus that: clogs the lungs and leads to life-threatening lung infections;  obstructs the pancreas; and stops  enzymes from helping the body break down food.
