Cholestatic gastritis is the reflux of bile from the duodenum to the stomach, causing alkaline burns such as gastric mucosa, a condition that requires an electrogastroscopy to clarify. This disease is directly related to eating too much food, eating too much fatty food and drinking alcohol and other bad habits. The first step in its treatment is to control bad habits, not to drink alcohol, and to eat less spicy, fried, greasy and other irritating foods. In terms of medication, you can consider using mosapride citrate + sodium ursodeoxycholate, aluminum phosphate gel to treat the condition for more than 3 weeks. In addition, in terms of behavior, take a walk or massage the upper abdomen in a clockwise direction after meals to promote gastric emptying and reduce bile reflux upwards.
