The full medical name of HP is Helicobacter pylori, which can be detected by C13 breath test, and HP positivity usually does not affect the life expectancy of patients. HP is a bacterium that lives in the sinus of the stomach and is a common cause of gastric ulcers, duodenal ulcers, erosions of the gastric mucosa and other digestive diseases. Most patients tested positive for HP, but gastroscopy is normal, the life expectancy of these patients will not be affected. If a patient is HP positive with peptic ulcer, early cancer and other diseases, if not treated aggressively, it may have an impact on survival time, and the impact varies from person to person. Current guidelines in China recommend that HP positivity requires eradication treatment, and the breath test should be repeated 4-6 weeks after taking the drug to assess whether HP is eradicated.
