Firstly, bronchiectasis is incurable, but its treatability cannot be judged solely by whether it can be cured or not. Some bronchiectasis patients have no clinical symptoms, and such patients do not need treatment. They only need regular check-ups and to maintain proper lifestyle habits. However, for patients who experience frequent disease attacks, strict prevention is necessary to avoid triggers such as infections and fatigue. Using sensitive medications during disease flare-ups can also lead to improvement.
