Causes of erosive gastritis

The causes of various gastritis are different. The main factors include two categories: the first is gastric acid, which will damage the gastric mucosa, leading to erosion and erosive gastritis; the second is Helicobacter pylori infection, which will colonize the gastric mucosa after the patient is infected. The submucous layer secretes various toxins to damage the gastric mucosa, leading to mucosal erosion.
