Bronchiectasis cannot be cured, but mild bronchiectasis is usually treated to relieve symptoms and slow the progression of the disease. Bronchiectasis refers to the destruction of the elastic tissue along with the muscles in the walls of the bronchial tubes, which triggers the patient’s bronchial tubes to undergo persistent dilatation or outright deformation. Once the lesion occurs, it is irreversible. The causes of bronchiectasis are diverse, ranging from acquired factors such as bacterial or viral infections to congenital genetic diseases such as primary ciliary immobility syndrome. Treating the cause of the disease can improve the symptoms and slow down the progression of bronchiectasis. It is important to note that after the diagnosis of bronchiectasis is confirmed, you should go to a regular hospital to clarify the cause of the disease and follow the doctor’s instructions for appropriate treatment.
