What is the difference between non-atrophic gastritis and atrophic gastritis

Non-atrophic gastritis is chronic non-atrophic gastritis, which differs from atrophic gastritis in definition, etiology and severity.

1. Definition

Chronic non-atrophic gastritis is a disease dominated by lymphocyte and plasma cell infiltration, which may be accompanied by erosion and bile reflux, but without chronic inflammatory changes of gastric mucosal atrophy and metaplasia. Atrophic gastritis is a chronic gastric disease caused by repeated damage to gastric mucosa epithelium, which promotes atrophy of inherent glands, accompanied or not accompanied by intestinal metaplasia and pseudopyloric metaplasia.

2.

The basic cause of chronic non-atrophic gastritis is Helicobacter pylori infection. Other causes include bile reflux, alcoholism, long-term use of non-steroidal anti-inflammatory drugs, etc. In addition to the above factors, the etiology of atrophic gastritis is closely related to the occurrence of this disease due to abnormal autoimmune mechanism and genetic factors.

3. Severity

Chronic non-atrophic gastritis is relatively serious compared with atrophic gastritis, because if atrophic gastritis persists, it can develop into gastric cancer after experiencing intestinal metaplasia, dysplasia and other steps.
