Cystic fibrosis is a genetic disorder that affects the lungs and digestive system. It is caused by mutations in the CFTR gene, which leads to the production of thick, sticky mucus that can clog the airways and blocks the pancreas, the organ located behind the stomach that produces enzymes to help digest food and hormones. Symptoms of cystic fibrosis vary but often include persistent coughing, frequent lung infections, difficulty breathing, poor growth, and digestive problems such as difficulty digesting food and absorbing nutrients. Cystic fibrosis is a lifelong condition that requires ongoing medical care. Treatment typically involves medications to thin mucus, prevent infections, improve lung function, and support digestion, as well as therapies and exercise to help clear mucus from the lungs.
