Bronchiectasis is short for bronchiectasis, which can be trained through abdominal breathing to improve patients’ quality of life and lung function. Bronchiectasis is a chronic inflammatory disease of the airways caused by structural destruction of the bronchial wall, abnormal and persistent dilatation of the bronchial tubes due to a variety of causes, and the main symptoms include coughing, coughing up sputum, recurrent hemoptysis, and respiratory distress. Clinical studies have shown that abdominal breathing has significant positive effects on the treatment of patients with bronchiectasis. The early use of abdominal breathing exercises has enabled patients to improve lung ventilation and gas exchange function, reduce the number of recurrent episodes of lung disease, and slow down the development of the disease. If you suffer from bronchiectasis, you should go to the hospital for treatment without delay, so as not to cause deterioration and delay of the disease.
