This question is actually very difficult to answer because no doctor can predict exactly how long their patient will live. They can only provide a general prognosis of the disease. Bronchiectasis is relatively a benign condition. The prognosis for most patients depends mainly on the severity of the bronchiectasis and their comorbidities, among other factors. Generally, if a patient’s bronchiectasis is not very severe and mild, and does not affect lung function or is not compounded by other underlying diseases, they might experience long-term, recurrent coughing and sputum production, requiring long-term hospitalization. However, if they do not experience acute complications associated with bronchiectasis, such as asphyxiation caused by hemoptysis, then actually they can live for a long time. There are many patients who are in their seventies or eighties and frequently admitted to the hospital. When asked how long they have had bronchiectasis, their condition might span over forty or fifty years, or even longer. This means that patients with bronchiectasis can live for a long time, provided their condition is relatively stable and they don’t suffer from acute complications such as severe bleeding or asphyxiation. However, if the bronchiectasis is severe, or unfortunately, even if the bronchiectasis isn’t very severe, if a patient suffers from major hemoptysis, it can cause asphyxiation rapidly leading to death within minutes. Therefore, it is impossible for doctors to predict exactly how long each patient will live.
