Bile reflux gastritis can cause stomach pain, often presenting as pain in the upper abdomen, typically as dull or distending pain which are most commonly seen in clinics. Bile reflux gastritis is generally considered a common disease, characterized by symptoms such as abdominal pain, bloating, and nausea at onset. Diagnosis largely relies on gastroscopy, during which we can observe inflammatory changes in the gastric mucosa, with the mucosa appearing congested and swollen, and the gastric mucus appearing yellow, generally considered to be caused by bile reflux. The treatment for bile reflux gastritis typically consists of dietary adjustments and medications. Dietary recommendations include regular, bland meals, and avoiding intake of coffee, alcohol, and spicy or irritating foods. Medications may include acid reducers, gastroprotective agents, and anti-reflux drugs. A typical course of treatment lasts from 7 to 14 days. Of course, if a patient has severe symptoms or recurrent episodes, a minimal maintenance dose may be used to relieve symptoms. (Note: Medication should be taken under the guidance of a professional doctor.)
