Constant bloating in atrophic gastritis is mainly related to gastrointestinal dysfunction, reduced digestion and absorption, and slow gastrointestinal peristalsis. 1. Atrophic gastritis is a gastric disease characterized by atrophy of the intrinsic glands of the gastric mucosa, accompanied by intestinal epithelial hyperplasia. Typical symptoms are epigastric pain, abdominal distension, abdominal discomfort, vague pain, burning pain and so on. The etiology is unknown, mainly related to Helicobacter pylori infection, bile reflux and other factors. 2. Bloating refers to the subjective feeling of abdominal swelling or distension, which can also refer to the feeling of gas filling or abdominal cavity filling, which can lead to an increase in abdominal wall tension or abdominal pressure, often accompanied by an increase in abdominal circumference and abdominal distension. If the inflammatory reaction of atrophic gastritis involves the body of the stomach, it may lead to a decrease in gastric acid secretion or the absence of gastric acid secretion, which further leads to the inability of food to be well digested, thus leading to the feeling of abdominal distension. If atrophic gastritis is diagnosed, it should be treated under the guidance of a doctor. Take rest on weekdays, have a proper diet, stop smoking and drinking, and maintain a regular routine.
