Cystic fibrosis is a genetic disorder that affects the lungs, pancreas, and other organs [1]. It is an inherited disease characterized by the buildup of thick, sticky mucus that can damage many of the body's organs [4]. Symptoms include difficulty breathing, coughing up mucus, poor growth and weight gain despite good appetite, salty-tasting skin and frequent lung infections [2]. People who have cystic fibrosis have a faulty protein that blocks airways and leads to lung damage as well as traps germs and makes infections more likely [3]. Treatment includes medications to help clear mucus from the lungs as well as antibiotics to treat infection. Other treatments may include physical therapy or surgery to remove blockages in the airways or digestive system [5].

Cystic fibrosis (CF) is a genetic disorder that affects the lungs, digestive system, and other organs in the body. It is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Symptoms of CF can include difficulty breathing, frequent lung infections, poor growth and nutrition, salty-tasting skin, and infertility in males. Treatment for CF includes medications to help reduce inflammation and mucus buildup in the lungs as well as antibiotics to treat infections. In some cases, surgery may be necessary to remove blockages or correct structural problems with the airways or digestive tract.
