Patient: Description of condition (onset, main symptoms, hospital visited, etc.): My mother had her gallbladder removed 7 years ago, had a stomach ulcer, erosion, she always felt something blocking her esophagus, and always had acid reflux in the morning, then I took him to the hospital for a gastroscopy, said it was bile reflux, and took medicine for a while to get better. Now he has symptoms again, how can I follow up the bile reflux problem? Doctor: It is possible that bile reflux causes GERD. After cholecystitis, bile secretion without storage function goes directly to the duodenum, and when the stomach is diastolic, it is easy to reach the stomach cavity, and if the lower esophageal sphincter is not fully functional, it will cause GERD. You can use bile neutralizing magnesium aluminum carbonate, and strengthen the gastric emptying of gastrokinetic drugs such as Mosapride, heartburn and acid reflux can be added with proton pump inhibitors.
