Bile reflux gastritis, primarily, its symptoms are caused by the damage of bile to the gastric mucosa, manifesting as acid reflux, belching, abdominal pain, and bloating. This can lead to damage to the gastric mucosa, resulting in erosion and bleeding. In cases of bile reflux gastritis where symptoms are not particularly typical, symptoms may be alleviated by improving dietary habits. More severe cases require medication, including oral drugs that promote gastrointestinal motility, protect the gastric mucosa, and inhibit gastric acid secretion. It is important to maintain a light diet, avoid highly irritating foods, and prevent irritation from smoking and alcohol.
