Gastric reflux presents with a cough that is predominantly dry. There are more causes of gastroesophageal reflux, and the common ones are reduced esophageal clearance, anti-reflux barrier, and abnormal function, which lead to gastric reflux. Gastric reflux is mainly gas reflux, liquid reflux and chyme reflux, showing different symptoms. If more gas is produced in the stomach, gas reflux is likely to occur, manifesting as hiccups and belching. Some patients are prone to liquid reflux, and the reflux itself is acidic and irritating, with heartburn and chest pain. At this time, the patient will noticeably feel that some liquid will rush from the stomach and epigastric region all the way to the sternum and throat causing a dry cough. Patients with celiac reflux find that food that has been completely swallowed will reflux into the mouth or esophagus, causing discomfort in the throat area and also causing coughing chest pain, heartburn, and acid reflux.
