Get StartedSymptoms
By Mayo Clinic staffSmall polyps usually don't cause symptoms. However, as a stomach polyp enlarges, ulcers may develop on its surface, or rarely, the polyp may block the opening between your stomach and your small intestine.
If you have stomach polyps, you may experience:
- Abdominal pain, or tenderness when you press your abdomen
- Bleeding
- Nausea and vomiting
- A sense of fullness too soon while you're eating
Signs and symptoms of inflammation of the stomach (gastritis), which may lead to hyperplastic polyps and adenomas, also include abdominal pain, as well as belching, bloating, nausea and bleeding signaled by blood in the vomit or black stools.
People with familial adenomatous polyposis (FAP), which is associated with fundic gland polyps, may also develop hundreds of colorectal polyps at a young age. Signs and symptoms of colorectal polyps include bleeding and fatigue.
When to see a doctor
If you have any signs or symptoms of problems that could indicate stomach polyps or the conditions leading up to them, including bleeding or persistent pain or discomfort, consult your doctor.
