The life expectancy of patients with bronchiectasis is related to the severity of the disease, the presence or absence of complications, and whether they are actively treated, and cannot be generalized. In simple bronchiectasis, if there are no complications, active control generally does not affect life expectancy, and attention should be paid to preventing infection, carrying out appropriate physical exercise, strengthening nutrition, and improving their immunity. If bronchiectasis is complicated by pneumonia, lung abscess, pneumothorax, or even extensive fibrosis of the lung tissue, it can lead to pulmonary hypertension, resulting in chronic pulmonary heart disease, respiratory failure, and heart failure, which can endanger the patient’s life. Patients should be aware that bronchiectasis is not a terminal disease, as long as active treatment, the disease can generally be effectively controlled, patients should pay attention to rest, emotional adjustment, avoid staying up late, so as not to reduce resistance.
