What Are the Symptoms of Stomach Polyps?

Stomach polyps, also called gastric polyps, are small growths that collect along the interior lining of the stomach. This condition is rare, affecting only about 1 percent of people who have their stomach lining examined by a doctor during a procedure called an upper gastrointestinal endoscopy, according to 2008 information available on OhioHealth.com. Though certain people with these growths may not develop symptoms, symptomatic people should seek prompt medical care to ensure receipt of appropriate treatment.

Nausea or Vomiting

Growths that develop in the lining of the stomach can inflame and irritate this region of the digestive tract. When this occurs, people with stomach polyps can experience nausea or vomiting as symptoms, according to MayoClinic.com. These symptoms can be constant or may arise intermittently, particularly after eating. Persistent nausea or vomiting can contribute to a diminished appetite, and affected people should consult a physician for further evaluation.

Stomach Fullness

Those with stomach polyps can experience a sensation of fullness in the stomach shortly after eating a small amount of food, OhioHealth.com explains. Inadequate food consumption due to early satiety can cause unintended weight loss in certain individuals with this condition.

Abdominal Pain

Large stomach polyps can cause significant inflammation within the abdominal region. Consequently, people with these types of growths can experience sensations of abdominal pain, particularly when pressing into the abdominal region with a finger or hand, MayoClinic.com warns. Sensations of abdominal pain can vary from mild to severe, and typically occur in conjunction with nausea or vomiting. People who develop sudden or severe abdominal pain should seek emergency care from a hospital, as this symptom can be a sign of an alternate medical condition, such as appendicitis.


Internal bleeding is a potential symptom of stomach polyps, Chicago Endoscopy Center reports. People with this condition can notice small amounts of blood within their stools or vomit due to bleeding in the stomach. Excessive internal bleeding is a medical emergency and can cause symptoms of lightheadedness, weakness or loss of consciousness.
