Bile reflux gastritis can be reviewed with gastroscopy once every six months to a year. Bile reflux gastritis is a common gastric disease caused by the reflux of duodenal contents into the stomach, usually with digestive symptoms such as abdominal pain, heartburn, nausea, vomiting, etc. It can be treated with medications such as omeprazole and bismuth potassium citrate after the diagnosis is confirmed by gastroscopy and Helicobacter pylori test. Bile reflux gastritis can be reviewed by gastroscopy once a year or so after the gastrointestinal symptoms have been relieved or disappeared after drug treatment. However, if the gastrointestinal symptoms do not improve after medication or recur after stopping medication, it is recommended to have a gastroscopy once every six months. If bile reflux gastritis occurs, it is recommended to consult a hospital and take medication or other treatments as prescribed by the doctor.
