Bile reflux gastritis is generally believed to be caused by bile reflux leading to inflammation in the stomach. It can cause abdominal discomfort in patients, where the discomfort typically presents as abdominal pain, bloating, nausea, and vomiting. The abdominal pain is often in the upper abdomen, characteristically above the navel and typically episodic; it may improve after eating, with fasting pain being the most common. The pain is primarily in the upper abdomen, without accompanying radiating pain to the upper back, fever, etc. Nausea and vomiting are also fairly common, considered to be reactions of the digestive tract, and closely related to bile reflux. Regarding treatment, the main approaches include dietary adjustments and medication. Medications can include acid reducing, stomach protecting, and anti-bile reflux drugs. For diet, it is recommended that patients maintain a regular, bland diet and avoid spicy and irritating foods. (Medication should be used under the guidance of a doctor.)
