Biliary reflux gastritis is a type of gastritis, more common in clinical practice, in which bile produced by the liver enters the duodenum via the common bile duct at the gallbladder, which is closely connected to the pylorus of the stomach. Either a problem with the pylorus or a problem with the duodenal sphincter can cause bile reflux, with unconjugated bile salts and pancreatic enzymes in the bile being the main attacking factors involved in damaging the gastric mucosa. The symptoms vary in severity and are as follows: 1. Bitterness in the mouth: bile is alkaline, with a pH value of 7.4 and a bitter taste. Usually patients with bile reflux gastritis will have a bitter mouth. 2. Stomach pain: Usually there will be stomach pain, heartburn and acidity. Bile salts and pancreatic enzymes are involved in damaging the gastric mucosa resulting in an uncomfortable feeling in the stomach that manifests as burning pain. 3. Pain in the right rib cage area: Many patients report pain in the right hepatobiliary area, which is often misdiagnosed as cholecystitis and confirmed as bile reflux gastritis by gastroscopy. At first, it is flashing pain and will become persistent pain as the condition worsens. 4, saliva, like to eat cool drinks: bile reflux gastritis patients feel more comfortable eating some cool fruits and other foods because of the burning sensation in the stomach. Therefore, the symptoms of bile reflux gastritis manifest mainly as heartburn, burning, flatulence, acid reflux and pain. Its treatment should be based on the etiology of the disease to choose the appropriate means. It is recommended to seek timely medical consultation and standardized treatment.
