Some people with reflux esophagitis will have a cough, which is usually caused by reflux of stomach and duodenal contents stimulating the esophagus and airway, so the effect of simple cough suppressants is relatively poor. Therefore, treatment of cough caused by reflux should be preceded by treatment of gastroesophageal disease as follows: 1. Lifestyle improvement: It is the basis for all other treatments. Quit smoking and alcohol, avoid eating high-fat, coffee, chocolate, spicy and stimulating, greasy foods, do not eat 3 hours before bedtime, elevate the head of the bed 15-20 cm when sleeping, and avoid lying down immediately after eating during the day. For obese or overweight patients, it is recommended to control weight and maintain a reasonable weight. 2. Drug therapy: mainly acid suppressants, prokinetic agents and gastric mucosal protectors, acid suppressants include proton pump inhibitors, H2 receptor antagonists, prokinetic agents include mosapride, etc. 3. If drug therapy is not effective, endoscopic treatment may be required.
