Cystic fibrosis (CF) is a non-contagious disease caused by an inherited genetic defect. About 1 in 23 Americans carries at least one defective gene for CF, making it the most common serious genetic defect in the US. CF commonly affects the nose and sinuses. Sufferers are also prone to polyps. Their mucus becomes sticky and thick. Treatments include frequent irrigation of the nose and sinuses and topical antibiotics.
People with cystic fibrosis also suffer from chronic lung problems and digestive disorders. Their lungs become coated with sticky mucus, a condition which promotes bacterial infection and is difficult to treat. Many people with CF require frequent hospitalizations and continuous use of antibiotics, enzyme supplements, and other medications.
