Risk factors

Factors that increase your chances of developing stomach polyps include:

• Age. Stomach polyps are more common among people in midadulthood to late adulthood.
• Bacterial stomach infection. Helicobacter pylori (H. pylori) bacteria are a common cause of the gastritis that contributes to hyperplastic polyps and adenomas.
• Familial adenomatous polyposis. This rare, inherited syndrome increases the risk of colon cancer and other conditions, including stomach polyps.
• Certain medications. Long-term use of proton pump inhibitors, which are medications used to treat gastroesophageal reflux disease, has been linked to fundic gland polyps.
