Positive H. pylori indicates the presence of H. pylori infection in the patient’s stomach. H. pylori is a gram-negative bacterium that parasitizes the human stomach, and its infection is closely related to the development of chronic gastritis, peptic ulcer, gastric cancer and other diseases. The examination of H. pylori is usually done by carbon 13 or carbon 14 breath test, rapid urease test, etc. If the test result is positive, it means that there is H. pylori infection in the stomach and timely treatment is needed. At present, the clinical treatment of H. pylori is often carried out through quadruple therapy for eradication, that is, a proton pump inhibitor (such as omeprazole, etc.) + two antibiotics (metronidazole, amoxicillin, clarithromycin, etc.) + a bismuth agent (such as bismuth potassium citrate, bismuth pectin, etc.). It should be noted that alcohol consumption is strictly prohibited during treatment. Patients who are positive for Helicobacter pylori are advised to seek timely medical attention and actively undergo treatment. The medication must be taken in strict accordance with the doctor’s prescription, and must not be used on its own, so as not to delay or even aggravate the condition.
