There is currently no vaccine for H. pylori, a microaerobic and anaerobic bacterium. There is no vaccine for this bacterium, so most H. pylori infections require a complete carbon 13 or carbon 14 breath test. If the DPM is more than 700dpm/mmol, anti-H. pylori medication is needed, but if it is less than 200dpm/mmol, most of them can be considered to continue clinical observation and do not need special treatment. If it is between 200-700dpm/mmol, gastroscopy should be completed. If there are related symptoms and gastroscopy shows gastritis, gastric erosion, gastric ulcer, etc., anti-Helicobacter pylori treatment is needed. If there are no such symptoms, most of them can be considered to continue to observe, and do not need to give special treatment. Instead, most clinical treatments for H. pylori use gastric 3-combination or gastric 4-combination drugs, which usually require 2 weeks of treatment. H. pylori is not particularly scary, and does not require special too concerned, as long as the amount of treatment has not reached the disease, most can consider continuing clinical observation.
