Dyspepsia may cause clinical symptoms of coughing because there are many causes of dyspepsia, including gastroesophageal reflux disease (GERD), which can lead to dyspepsia, and GERD can cause typical coughing symptoms, which are often of a subacute nature. GERD is caused by excessive secretion of gastric acid, which leads to reflux in the stomach and esophagus, and the reflux of gastric contents into the pharynx can irritate the pharynx, resulting in clinical symptoms of coughing, which is often accompanied by retrosternal burning pain, belching, and acid reflux. Therefore, it is necessary to give timely acid control and gastric protection treatment, such as the use of omeprazole or pantoprazole and other drugs to carry out the treatment, and generally do not use cough suppressant drugs treatment.
