Polyps in the stomach usually refers to gastric polyps, the etiology and pathogenesis is not clear, mostly considered to be caused by Helicobacter pylori infection, long-term application of proton pump inhibitors and other factors. 1. Helicobacter pylori infection: Helicobacter pylori infection is an important cause of chronic gastritis, the gastric mucosa in the long-term chronic inflammation stimulation, will make the mucosal epithelium overgrowth, resulting in polyp formation. 2. Long-term application of proton pump inhibitors: proton pump inhibitors can inhibit the secretion of gastric acid, so that the human body is in a state of low gastric acid for a long time, which can increase the incidence of gastric polyps. 3. Bile reflux: bile is a strong alkaline material, reflux into the stomach can destroy the acidic environment of the stomach, inducing the formation of polyps. 4. Atrophic gastritis: the patient’s gastric mucosal epithelial cells have abnormal proliferation, which can also lead to the formation of gastric polyps. In addition, improper diet, irregular work and rest, overeating, smoking and drinking, emotional instability and other factors will also increase the incidence of gastric polyps. If gastric polyps are present, it is recommended to seek timely and active treatment to avoid delaying the condition.
