Non-atrophic gastric sinusitis is a pathohistologic description of superficial gastritis that occurs in the gastric sinus without atrophy of the epithelium of the gastric mucosa and reduction of the intrinsic glands. It is possible that superficial gastritis occurring in the area of the gastric sinus is related to Helicobacter pylori infection, the use of non-steroidal anti-inflammatory drugs, dietary irregularities, and the use of spicy and irritating foods. On examination of the gastroscope, congestion and edema of the gastric mucosa, infiltration of lymphocytes and plasma cells in the lamina propria can be seen, but the intrinsic glands do not undergo atrophy. Symptoms such as epigastric pain, dyspepsia, nausea, vomiting, and acid reflux may occur. If gastroscopy shows non-atrophic sinusitis, further tests such as the Helicobacter pylori breath test are needed to find the cause. It is also necessary to eat a light diet, quit smoking and alcohol, do not eat cold, greasy, fried, barbecue and other foods, and regularly review the Helicobacter pylori breath test, gastroscopy and other programs.
