Cystic fibrosis is an inherited disease that affects the body’s secretions, including mucus in the lungs. When mucus becomes abnormally thick, it can block airways and make it easier for bacteria to grow, increasing the risk of infections and chronic inflammation. Over time, repeated damage can affect breathing and overall lung health.
Because cystic fibrosis is a lifelong condition, regular pulmonary follow-up is an important part of care. Treatment is often focused on symptom control, infection management, airway clearance, and protecting lung function for as long as possible.
