Abdominal breathing can be effective in relieving the symptoms of alveoli, but it does not treat the root cause of alveoli. Abdominal breathing is a method of breathing exercises to improve ventilation. Symptoms such as dyspnea, chest tightness, shortness of breath, coughing, pneumothorax, chest pain, coughing up sputum, and fever can occur with pulmonary alveoli. Abdominal breathing in patients with pulmonary alveoli is effective in relieving their symptoms. Abdominal breathing is mainly based on diaphragmatic movement, and the upper and lower diameter of the thorax increases during inhalation to achieve the purpose of increasing tidal volume. Abdominal breathing can improve pulmonary circulation, increase pulmonary ventilation, increase the range of diaphragmatic motion, improve lung function, increase lung capacity, and thus have a certain benefit on the symptomatic relief of pulmonary alveoli. However, abdominal breathing cannot cure alveoli, only improve the symptoms. Patients with pulmonary alveoli do not need to be treated when they are asymptomatic; when combined with other lung diseases, the primary disease should be controlled and treated, and surgery should be given to severe cases. When alveoli appear, it is recommended to treat them according to the test results and under the guidance of the doctor.
