Erythematous exudative gastritis is accurately called chronic non-atrophic gastritis, in which erythematous, exudative changes in the gastric mucosa can be seen under electronic gastroscopy, without the presence of foci of erosion, much less ulcerative form. Some doctors are used to diagnose erythematous exudative gastritis and others are used to diagnose non-atrophic gastritis. Erythema exudatum gastritis is a very mild form of the disease and can be treated without medication if the patient does not have clinical symptoms. If patients have clinical symptoms, they can be given appropriate medication for the symptoms, such as acid suppressants like omeprazole and lansoprazole when abdominal pain is present. In case of abdominal distension and dyspepsia, you can choose to use compound digestive enzymes or domperidone or mosapride, etc. The specific medication should be used under the guidance of a specialist.
