Polyp in the stomach mainly refers to the appearance of raised, bulging tissue on the surface of the gastric mucosa, and its main causative factors are not yet clear. The main symptoms are: 1. upper abdominal distension and discomfort, mainly due to the stimulation of gastric polyps leading to upper abdominal discomfort, especially after eating. 2. gastrointestinal bleeding, mainly due to the dislodgement of gastric polyps, piercing polyps after eating raw food and polyps with tips into the duodenum. However, a small amount of gastric bleeding is manifested by positive fecal occult blood, and in severe cases, black stool. Electronic gastroscopy can clarify the examination of gastric polyps and the nature of benign and malignant. The main treatment is endoscopic high-frequency electrocoagulation resection and major gastrectomy for polyps suspected to be malignant. In addition, H. pylori has a significant relationship with the proliferation of polyps, so the treatment of gastric polyps should be accompanied by the eradication of H. pylori.
