Reflux gastritis, i.e. bile reflux gastritis, is generally less serious. Bile reflux gastritis refers to the chronic inflammation, erosion and even ulceration of the gastric mucosa caused by the reflux of bile and pancreatic juice from the duodenum into the stomach. It can be caused by hepatobiliary and pancreatic diseases, peptic ulcer, diabetes mellitus, gastrointestinal surgery, etc. It mainly manifests as epigastric pain, abdominal distension, nausea and vomiting, etc., and in severe cases, it can lead to gastrointestinal hemorrhage, vomiting blood, black stool and other symptoms. Mild cases can be treated with medication such as gastric mucosal protectants like misoprostol, gastric stimulants such as mosapride, acid inhibitors such as omeprazole, and changing lifestyle habits to avoid staying up late and eating spicy and stimulating foods. Patients with severe reflux symptoms or failed drug treatment can choose surgical treatment. Reflux esophagitis is recommended to consult a doctor in time to clarify the diagnosis and carry out targeted treatment. All of the above medications should be taken under the guidance of a doctor and should not be used without authorization.
