Feeling the symptoms of dyspnea in the abdomen actually means that the dyspnea is extremely severe. Under normal circumstances, the human body, especially women, is mainly thoracic respiration, mainly through the contraction and diastole of the respiratory muscles distributed around the lungs, so that the alveoli expansion and contraction of the formation of respiratory movement, mainly to eliminate carbon dioxide inhalation of oxygen, gas exchange, the formation of normal metabolism. When the airway is infected with a more serious infection, such as bronchitis, pneumonia, lung abscess or acute attack of bronchial asthma, there will be extreme dyspnea at this time. Chest breathing does not allow for normal lung ventilation and exchange, and the abdominal muscles are forced to participate in respiratory movements, resulting in abdominal dyspnea.
