Bronchiectasis generally refers to bronchial dilatation, and mild bronchiectasis may worsen. Bronchiectasis is a respiratory disease caused by the destruction of the bronchial structure, so that the bronchial tubes are irreversibly dilated and deformed, even if they are suffering from mild bronchiectasis, the patient may also experience deterioration of the condition. First of all, bronchiectasis cannot be cured, the treatment can only control the symptoms, and secondly, if the patient does not receive standardized treatment, the patient’s condition will deteriorate, and even life-threatening. Therefore, no matter whether you are suffering from mild bronchiectasis or severe bronchiectasis, you need to receive standardized treatment to reduce the number of acute exacerbations caused by respiratory infections, to prevent further deterioration of the expansion, and to maintain the stability of lung function. Only treatment can slow down the progression of the disease, prevent it from worsening, and prevent the individual’s life expectancy from being unduly affected. If you suspect that you have bronchiectasis, it is recommended that you seek treatment promptly.
