Chronic non-atrophic gastritis of the gastric sinus is a chronic, inflammatory condition that occurs in the area of the gastric sinus without atrophy and thinning of the mucosa of the sinus. Chronic non-atrophic gastritis of the gastric sinus is the way it is described gastroscopically. Chronic means that the inflammation has been present for a long time, and non-atrophic means that the mucosa of the gastric sinus is not atrophic and has little effect on the absorptive and secretory function of the gastric sinus. Gastritis refers to symptoms of congestion and edema of the gastric mucosa, thickening and swelling of the mucosal folds. Chronic atrophic gastritis of the gastric sinus is a relatively mild chronic inflammation of the gastric sinus, which may be related to dietary irregularities, alcohol consumption, medications, excessive consumption of oily foods, Helicobacter pylori infection, smoking and other reasons. Symptoms such as acid reflux, stomach pain, bloating, nausea, and vomiting may occur. When chronic non-atrophic gastritis of the gastric sinuses is present, it is recommended to further examine the Helicobacter pylori breath test and other programs to find out the cause and then treat it under the guidance of a doctor.
