GERD cough is characterized by a dry and prolonged cough, chest tightness, and acid reflux. GERD cough is a cough-based gastroesophageal reflux disease (GERD) that is usually caused by the reflux of stomach acid or other stomach contents into the esophagus. Dry cough or coughing up a small amount of white mucous sputum, acid reflux, belching, chest tightness, and a burning sensation behind the sternum are usually symptoms of GERD cough. A cough that lasts for a long time is also a characteristic of GERD cough, and patients usually have coughs associated with significant eating, such as cough after meals and eating cough. If any of these symptoms occur, it is recommended to go to the hospital promptly for early and regular treatment.
