Symptoms

Stomach polyps usually don't cause signs or symptoms.

But as a stomach polyp enlarges, open sores (ulcers) can develop on its surface. Rarely, the polyp can block the opening between your stomach and your small intestine.

Signs and symptoms include:

• Pain or tenderness when you press your stomach
• Nausea
• Blood in your stool
• Anemia

When to see a doctor

See your doctor if you have persistent blood in your stool or other signs or symptoms of stomach polyps.
