Bile reflux gastritis is often caused by the retrograde movement of bile from the duodenum into the stomach, leading to a series of symptoms. These can include upper abdominal pain, bloating, heartburn, and a bitter taste in the mouth. The fundamental cause of this condition is usually insufficient gastric motility or gastrointestinal motility. Regarding medication, the first choice generally includes acid-suppressing and pro-motility drugs, such as proton pump inhibitors combined with gastric motility drugs. Additionally, aluminum magnesium carbonate has the effect of neutralizing stomach acid and bile salts, which can help with bile reflux gastritis. At the same time, it is necessary to develop good dietary and living habits, and avoid excessive eating and drinking, as well as stimulants like tobacco and alcohol. (Specific medication use should be carried out under the guidance of a doctor.)
