Kistik fibrozis, or cystic fibrosis, is a genetic disorder that affects the lungs and digestive system. It is caused by mutations in the CFTR gene, leading to the production of thick, sticky mucus. This mucus can clog airways, making it difficult to breathe and increasing the risk of lung infections. In addition to respiratory issues, kistik fibrozis can also impact the pancreas, hindering the absorption of nutrients. Patients often require specialized treatments, including medications and physical therapy, to manage symptoms and improve their quality of life. Early diagnosis and ongoing care are essential for better outcomes.
