Stomach bloating and stomach pain can cause shortness of breath and dyspnea. Stomach bloating and stomach pain can be seen in many gastrointestinal diseases, such as stomach tumors, gastric perforation, intestinal obstruction and other diseases can cause dyspnea; such as asthma, pulmonary fibrosis, chronic obstructive pulmonary disease and other diseases can also cause dyspnea. 1. Gastrointestinal diseases: stomach tumors can metastasize to the lungs and cause dyspnea; gastric perforation can lead to acute peritonitis, hemorrhage and other conditions, resulting in dyspnea; intestinal obstruction can lead to increased intra-abdominal pressure, which affects the pressure in the thoracic cavity, resulting in dyspnea. 2. Lung disease: patients with asthma, pulmonary fibrosis, chronic obstructive pulmonary disease and other diseases, gastric distension and stomach pain can lead to a decrease in the content of the chest cavity, lung expansion is limited, thus causing dyspnea.
