Chronic non-atrophic gastritis with bile reflux is mainly characterized by symptoms such as upper abdominal distension, belching, acid reflux, nausea, vomiting, poor appetite, and indigestion. A diagnosis can be made if bile reflux into the stomach or bile patches on the stomach wall are observed during gastroscopy. A Carbon-14 breath test is also necessary to determine the presence of Helicobacter pylori infection. If the infection test is positive, a 14-day anti-Helicobacter pylori treatment is required. Additionally, treatment for chronic non-atrophic gastritis with bile reflux should include acid suppression, gastric protection, and promotion of gastric motility to protect the gastric mucosa, with a treatment duration of about four to six weeks. Bile reflux-associated chronic gastritis is primarily caused by poor gastric motility, thus increasing physical exercise is recommended as it can enhance gastric motility and improve the condition.
