Gastric polyps are the cause of some symptoms of stomach and digestive diseases such as abdominal pain, bleeding, indigestion... Gastric polyps are detected during gastroscopy.

Epithelial polyps are the most common type of gastric polyp. They include fundic gland polyps (FGPs), hyperplastic polyps, and adenomatous polyps. Other less common epithelial lesions that may appear as polyps include neuroendocrine tumors (formerly called carcinoids), ectopic pancreatic tissue, and pyloric adenomas.
