Cystic fibrosis is a lifelong disease that affects the lungs and digestive system. About 30,000 children and adults in the United States have CF (70,000 worldwide). This disease is caused by a defective gene that makes the body produce very thick, sticky mucus. This mucus:
- Clogs the lungs and leads to lung infections
- Blocks the pancreas and prevents the normal breakdown and use of food by the body
