Risk factors

By Mayo Clinic staff

Factors that increase your chances of developing stomach polyps are:

  • Age. Most people with hyperplastic polyps and adenomas are in their 60s or older.
  • H. pylori infection. This is a common cause of the gastritis that contributes to hyperplastic polyps and adenomas. Experts aren't sure how people become infected with these bacteria, but H. pylori may be carried in food and water. H. pylori infection is more common in older adults.
  • Familial adenomatous polyposis. This condition is hereditary and is caused by genetic mutations that occur in one in 7,000 to 22,000 people.
  • Medication use. Long-term use of proton pump inhibitors (PPIs) such as omeprazole (Prilosec) — which are used to treat ulcers, gastroesophageal reflux disease (GERD) and H. pylori infection — has been linked to fundic gland polyps. However, it's not clear whether these medications actually cause polyp growth or whether polyp growth is due to the presence of H. pylori.
