Stomach polyps are growths that develop on the inner lining of the stomach. They are usually small and benign, meaning that they are not cancerous and do not spread to other parts of the body. However, in some cases, they may become cancerous over time.

The exact causes of stomach polyps are not well understood, but they are thought to be related to chronic inflammation or infection in the stomach, as well as genetic factors. Some studies have also suggested that certain medications, such as proton pump inhibitors (PPIs), may increase the risk of developing stomach polyps.

Most people with stomach polyps do not experience any symptoms, but in some cases, they may cause abdominal pain, nausea, vomiting, or other digestive problems. In rare cases, larger polyps may bleed, leading to anemia or blood in the stool.

Treatment of stomach polyps depends on the size, number, and location of the polyps, as well as the overall health of the individual. In most cases, small polyps that do not cause any symptoms do not require treatment, but regular monitoring with endoscopy and biopsy may be recommended to watch for any changes. Larger or symptomatic polyps may need to be removed with surgery or endoscopic techniques.

If a stomach polyp is found to be cancerous or at high risk of becoming cancerous, additional treatment may be necessary, such as surgery, chemotherapy, or radiation therapy. Regular follow-up care is also important for individuals with a history of stomach polyps, as well as for those who are at high risk for the condition due to family history or other factors.

Stomach polyps — also called gastric polyps — are masses of cells that form on the lining inside your stomach. These polyps are rare and usually don't cause any signs or symptoms.

Stomach polyps are most often discovered when your doctor is examining you for some other reason.

Most stomach polyps don't become cancerous. But certain types can increase your risk of stomach cancer. Depending on the type of stomach polyp you have, treatment might involve removing the polyp or monitoring it for changes.

Treatment depends on the type of stomach polyps you have:

• Small polyps that aren't adenomas. These polyps might not require treatment. They typically don't cause signs and symptoms and only rarely become cancerous. Your doctor might recommend periodic monitoring so that growing polyps or ones that cause signs and symptoms can be removed.
• Large stomach polyps. These might need to be removed. Most stomach polyps can be removed during endoscopy.
• Adenomas. These polyps can become cancerous and are usually removed during endoscopy.
• Polyps associated with familial adenomatous polyposis. These are removed because they can become cancerous.

Your doctor will likely recommend follow-up endoscopy to check for recurring polyps.

Treating H. pylori infection

If you have gastritis caused by H. pylori bacteria in your stomach, your doctor will likely recommend treatment with a combination of medications, including antibiotics. Treating an H. pylori infection can make hyperplastic polyps disappear and might also stop polyps from recurring.
