H. pylori is a bacterium that can cause peptic ulcer disease and gastritis. Only 20% of those infected have symptoms. Symptoms include dull or burning stomach pain, unplanned weight loss and bloody vomit. H-pylori-caused ulcers are commonly treated with combinations of antibiotics.
If you have an H. pylori infection, you have an increased risk for stomach cancer later in life. If you have a strong family history of stomach cancer and other cancer risk factors, even though you may not have symptoms of a stomach ulcer, your healthcare provider may recommend being tested for H. pylori antibodies. In addition to screening and treatment, your provider may suggest some lifestyle changes, such as including more fruits, vegetables and fibre in your diet. Regular check-ups with your provider and following their recommendations can reduce your cancer risk.
