Shortness of breath is a symptom of gastroesophageal reflux disease, according to Healthline. Other common symptoms of gastroesophageal reflux disease, or GERD, include heartburn, nausea, chronic sore throat, regurgitation and weigh loss for no apparent reason, notes WebMD.
GERD-related shortness of breath, or dyspnea, occurs when stomach acid ascends into the esophagus and causes passages in the throat to swell and restrict air flow, explains Healthline. It results in atypical asthma reactions, which impedes breathing, causes coughing and makes swallowing foods problematic. Treatment can alleviate shortness of breath, and usually involves lifestyle changes, such as diet modification, losing weight and avoiding foods that trigger GERD.
