Bile reflux gastritis is a type of chronic gastritis that is commonly seen in clinical settings. It is generally believed to be caused by bile reflux leading to inflammation of the stomach and discomfort. The symptoms of bile reflux gastritis typically include abdominal pain, bloating, nausea, and belching, among others, with abdominal pain being particularly common. The pain usually occurs in the upper abdomen, specifically above the navel, and is episodic, occurring less frequently at night. It is generally related to diet and tends to improve after eating. The common nature of the pain is usually a dull, bloating, or burning sensation. However, patients generally do not experience fever, anemia, emaciation, or weight loss. The treatment of bile reflux gastritis typically involves strengthening acid suppression and gastric protection, choosing some gastric protective and bile-antagonistic drugs. The treatment effectiveness is generally good and not overly concerning. (The use of drugs should be under the guidance of a doctor.)
