If chronic non-atrophic gastritis is active it is usually not serious; if it is left untreated for a long time and transforms into atrophic gastritis, it is more serious. Most people have mild chronic non-atrophic gastritis, and the prognosis is usually better if there is no obvious discomfort, mild symptoms or no erosion of the gastric mucosa on examination, only inflammation, mucosal congestion and edema. General symptoms include fullness, lack of appetite, nausea, dull pain, etc., which can be treated by medication, such as omeprazole, magnesium aluminum carbonate, etc., and the medication should be used under the guidance of a doctor. If anemia, anorexia, weight loss, vomiting blood, black stools and other symptoms occur during the active stage of chronic non-atrophic gastritis, or pathological examination reveals atrophy, intestinal epithelial hyperplasia, heterogeneous hyperplasia and other changes, which indicates that the transformation of non-atrophic gastritis into atrophic gastritis, the condition is more serious, with the possibility of cancer, and it is recommended to seek medical treatment in a timely manner.
