The symptoms of patients with gastric polyps depend on the size and location of the gastric polyps and the surface of the polyps. Gastric polyps are protruding papillary tissues growing on the surface of gastric mucosa. When they are small, they often have no obvious symptoms; when they are large, they are often accompanied by lack of or low gastric acid, which often manifests as mild discomfort in the upper abdomen, nausea, anorexia, indigestion, weight loss, feeling of fullness or mild upper abdominal pain. Stomach polyps are mostly distributed in the gastric sinus. Larger polyps obstructing the pylorus or the mucosal tissue of the stomach slipping into the duodenum can lead to the occurrence of pyloric obstruction, obstruction of food passage, gastric retention, gastric edema, epigastric pain, vomiting, restricted diet, which in turn leads to a state of general lack of nutrition and a series of systemic symptoms. Intermittent or persistent bleeding from the stomach can occur if the surface of the gastric polyp is eroded or ulcerated. Some gastric polyp lesions are tumorigenic in nature, a precancerous lesion that can become cancerous and can cause serious complications. In short, small gastric polyps have no obvious symptoms, while larger polyps may cause upper abdominal discomfort or even pyloric obstruction symptoms, etc. Since gastric polyps have a tendency to become malignant, if once found in the stomach polyps, it is recommended to get rid of them as soon as possible.
