Atrophic gastritis, also known as body-type gastritis, is mainly caused by Helicobacter pylori infection leading to atrophy of the gastric mucosa. Under microscopy, twisted blood vessels and alternating red and white mucosa can be seen. The main symptoms include nausea, vomiting, and decreased appetite. A reduction in parietal cells can lead to decreased secretion of intrinsic factor, thereby causing anemia with red blood cells. If atrophic gastritis is accompanied by ulcers, it can cause severe abdominal pain and bloody stools. It is important to adjust the diet, eat more soft and easily digestible foods, and consume fewer raw, cold, and spicy foods.
