Age is not the cause of bronchiectasis, the severity of bronchiectasis is related to chronic suppurative inflammation and fibrosis of the lung tissues around the bronchi, and the bronchi can and may remain in a relatively stable state with age.
Bronchiectasis is caused by the destruction of the muscle and elastic tissue of the bronchial wall following chronic suppurative inflammation and fibrosis of the bronchial tubes and surrounding lung tissues. Some patients have a decreased immune system, which may lead to recurrent bacterial infections and aggravation of symptoms.
Some patients have limited bronchiectasis, which has less impact on the body, usually with mild or no clinical symptoms, and may remain stable without aggravation as they age.
The more serious the degree of bronchiectasis, the greater the damage to the body, and it is important to go to the hospital for timely consultation and treatment.
