Causes and symptoms of chronic nonatrophic gastritis

Chronic non-atrophic gastritis occurs, usually with helicobacter pylori infection, long-term use of non-steroidal anti-inflammatory drugs, duodenal fluid reflux and other factors, its common symptoms are epigastric pain, acid reflux, hematochezia or hematemesis. 1. Etiology 1. Helicobacter pylori infection Helicobacter pylori infection is the most common cause of chronic non-atrophic gastritis. During the growth and reproduction of the bacteria in the stomach, some toxic substances can be metabolized, resulting in gastric mucosal damage and inflammation. 2, long-term use of non-steroidal anti-inflammatory drugs If long-term use of non-steroidal anti-inflammatory drugs, such as ibuprofen, aspirin, etc., these drugs will also cause damage to the gastric mucosa, thus inducing chronic non-atrophic gastritis. 3. Duodenal fluid reflux due to pyloric sphincter dysfunction, resulting in duodenal fluid reflux into the stomach, can increase the damage of gastric acid to the gastric mucosa, thus causing local damage and inflammatory reaction, leading to the occurrence of the disease. 2, acid reflux after chronic non-atrophic gastritis, due to inflammatory stimulation led to increased acid secretion, patients may also appear acid reflux symptoms. 3, hematochezia or hematemesis If the condition is more serious, leading to gastric mucosal ulcer, bleeding, may also appear hematochezia or hematemesis symptoms.
