These polyps are rare and usually don&#8217;t cause any symptoms. Stomach polyps also are called gastric polyps.<\/p>\n<p>Stomach polyps are most often discovered when a healthcare professional does an exam for some other reason.<\/p>\n<p>Most stomach polyps don&#8217;t become cancerous. But certain types can increase the risk of stomach cancer. Depending on the type of stomach polyp, treatment might involve removing the polyp or monitoring it for changes.<\/p>\n<p>Stomach polyps usually don&#8217;t cause symptoms.<\/p>\n<p>But as a stomach polyp gets bigger, open sores called ulcers can develop on its surface. Rarely, the polyp can block the opening between the stomach and the small intestine.<\/p>\n<p>Symptoms include:<\/p>\n<ul>\n<li>Pain or tenderness when the stomach is pressed.<\/li>\n<li>Nausea.<\/li>\n<li>Blood in the stool.<\/li>\n<li>Anemia. <\/li>\n<\/ul>\n<p>See a healthcare professional if you have blood in your stool or other symptoms of stomach polyps.<\/p>\n<p>The most common causes of stomach polyps are:<\/p>\n<ul>\n<li><b>Long-lasting stomach inflammation.<\/b> Also known as gastritis, this condition can cause the growth of hyperplastic polyps and adenomas. Hyperplastic polyps are not likely to become cancerous, although those larger than about 2\/5 inch (1 centimeter) carry a greater risk.\n<p>Adenomas are the least common type of stomach polyp but the type most likely to become cancerous. For that reason, they are usually removed.<\/p>\n<\/li>\n<\/ul>\n<ul>\n<li><b>Familial adenomatous polyposis.<\/b> This rare syndrome runs in families. It causes certain cells on the stomach&#8217;s inner lining to form a type of polyp called a fundic gland polyp. When associated with this syndrome, fundic gland polyps are removed because they can become cancerous. Familial adenomatous polyposis also can cause adenomas.<\/li>\n<li><b>Regular use of certain stomach medicines.<\/b> Fundic gland polyps are common among people who regularly take proton pump inhibitors to reduce stomach acid. These polyps are generally small and aren&#8217;t a cause for concern.\n<p>A fundic gland polyp with a diameter larger than about 2\/5 inch (1 centimeter) carries a small risk of becoming cancerous. A healthcare professional might recommend stopping proton pump inhibitors if possible; removing the polyp; or both.<\/p>\n<\/li>\n<\/ul>\n<p>Factors that increase the risk of forming stomach polyps include:<\/p>\n<ul>\n<li><b>Age.<\/b> Stomach polyps are more common among people in mid-adulthood to late adulthood.<\/li>\n<li><b>Bacterial stomach infection.<\/b> Helicobacter pylori (H. pylori) bacteria are a common cause of the gastritis that contributes to hyperplastic polyps and adenomas.<\/li>\n<li><b>Familial adenomatous polyposis.<\/b> This rare syndrome runs in families. It increases the risk of colon cancer and other conditions, including stomach polyps.<\/li>\n<li><b>Certain medicines.<\/b> Long-term use of proton pump inhibitors has been linked to fundic gland polyps. These are medicines used to treat gastroesophageal reflux disease.<\/li>\n<\/ul>\n<p>Tests used to diagnose stomach polyps include:<\/p>\n<ul>\n<li><b>Endoscopy,<\/b> to view the inside of the stomach with a scope.<\/li>\n<li><b>Tissue sample,<\/b> also called a biopsy, which can be removed during endoscopy and examined in a lab.<\/li>\n<\/ul>\n<p>Treatment depends on the type of stomach polyps someone has:<\/p>\n<ul>\n<li><b>Small polyps that aren&#8217;t adenomas.<\/b> These polyps might not require treatment. They typically don&#8217;t cause symptoms and only rarely become cancerous. A healthcare professional might recommend occasional monitoring so that growing polyps or ones that cause symptoms can be removed.<\/li>\n<li><b>Large stomach polyps.<\/b> These might need to be removed. Most stomach polyps can be removed during endoscopy.<\/li>\n<li><b>Adenomas.<\/b> These polyps can become cancerous and are usually removed during endoscopy.<\/li>\n<li><b>Polyps associated with familial adenomatous polyposis.<\/b> These are removed because they can become cancerous.<\/li>\n<\/ul>\n<p>A healthcare professional will likely recommend follow-up endoscopy to check for polyps that have come back.<\/p>\n<h3>Treating H. pylori infection<\/h3>\n<p>For gastritis caused by H. pylori bacteria in the stomach, a care professional will likely recommend treatment with a combination of medicines, including antibiotics. Treating an H. pylori infection can make hyperplastic polyps disappear and might stop polyps from coming back. <\/p>\n<p>You might start by first seeing someone on your healthcare team or you might be referred to a provider who specializes in the digestive system, called a gastroenterologist.<\/p>\n<p>Here&#8217;s some information to help you get ready for your appointment.<\/p>\n<h3>What you can do<\/h3>\n<p>When you make the appointment, ask if there&#8217;s anything you need to do beforehand, such as fasting before having a specific test. Make a list of:<\/p>\n<ul>\n<li><b>Your symptoms,<\/b> including any that seem unrelated to the reason for your appointment, and when they began.<\/li>\n<li><b>Key personal information,<\/b> including major stresses, recent life changes and family medical history.<\/li>\n<li><b>All medicines, vitamins or other supplements<\/b> you take, including the doses.<\/li>\n<li><b>Questions to ask<\/b> during your appointment.<\/li>\n<\/ul>\n<p>Take a family member or friend along, if possible, to help you remember the information you&#8217;re given.<\/p>\n<p>For stomach polyps, some questions to ask include:<\/p>\n<ul>\n<li>What&#8217;s likely causing my symptoms?<\/li>\n<li>What tests do I need?<\/li>\n<li>What&#8217;s the best course of action?<\/li>\n<li>I have these other health conditions. How can I best manage them together?<\/li>\n<li>Are there restrictions I need to follow?<\/li>\n<li>Should I see a specialist?<\/li>\n<li>Are there brochures or other printed material I can have? What websites do you recommend?<\/li>\n<\/ul>\n<p>Don&#8217;t hesitate to ask other questions.<\/p>\n<h3>What to expect from your doctor<\/h3>\n<p>You&#8217;ll likely be asked a few questions about your symptoms, such as:<\/p>\n<ul>\n<li>Have your symptoms been happening often or do they happen now and then?<\/li>\n<li>How bad are your symptoms?<\/li>\n<li>What, if anything, seems to improve your symptoms?<\/li>\n<li>What, if anything, seems to worsen your symptoms?<\/li>\n<li>Do you have a personal or family history of colon cancer, polyps or familial adenomatous polyposis?<\/li>\n<li>Do you take medicines to reduce stomach acid?<\/li>\n<\/ul>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>These masses of cells that form on your stomach lining usually don&#8217;t cause symptoms.
