Positive H. pylori alone with a value of 14 suggests the result value of C13 breath test, which is generally not serious and can be eradicated with four drugs; however, it is more serious when combined with malignant tumors such as gastric cancer, and requires admission to the hospital for active treatment. Simple and effective methods to detect H. pylori mainly include carbon 13 and carbon 14 breath test, in which the normal value range of carbon 13 breath test is generally 0 to 4, while the normal value range of carbon 14 breath test is generally 0 to 100, according to this standard to compare, H. pylori test value of 14 and positive refers to the results of the carbon 13 breath test, which is generally not very serious. Only H. pylori infection is not very serious, symptomatic drug treatment can be. But H. pylori can cause gastritis, gastric ulcer, gastric cancer, gastric mucosa-related lymphoid tissue lymphoma and other diseases, especially the latter two diseases belong to malignant tumors, the degree of which is relatively more serious, and need to be admitted to the hospital in time to check and receive treatment. At present, it is recommended to use four combinations of drugs to eradicate H. pylori, usually with proton pump inhibitors (such as ace omeprazole) + colloidal bismuth pectin + two kinds of antibiotics (such as amoxicillin, metronidazole, etc.), taking 10 to 14 days, stopping the drug for a month and then testing. Specific medications should be used as prescribed by a physician.
