The main symptoms of bile reflux gastritis include upper abdominal distension, belching, acid reflux, nausea, vomiting, and heartburn. A gastroscopy can reveal bile reflux into the stomach, which can then be diagnosed as bile reflux gastritis. The primary cause is closely related to poor gastric motility, so treatment mainly focuses on acid suppression, gastric protection, promoting gastric motility, and repairing the gastric mucosa, typically over a course of about six weeks. It is also recommended to increase physical activity, as exercise can promote gastrointestinal motility and enhance gastric power, which can have a positive effect on patients with bile reflux gastritis. In terms of diet, it is advised to consume light, easily digestible foods and to avoid fatty, rich, spicy, and other difficult-to-digest foods.
