You can check yourself for H. pylori infection easily, quickly and conveniently with a carbon 14 breath test. H. pylori is a special group of bacteria that is the only one that can live in the stomach. A carbon 14 breath test can detect the presence of H. pylori infection. If the test result is greater than 100 dpm/mmolCO2, it indicates the presence of H. pylori infection and should be treated with anti-H. pylori therapy. If you choose standard triple therapy or bismuth-containing quadruple therapy, that is, two antibiotics plus an acid suppressant, antibiotics can choose penicillins, quinolones, etc., acid suppressants mainly include omeprazole, rabeprazole, pantoprazole, etc., after 10-14 days of treatment, after 4 weeks of discontinuation of the drug recheck carbon 14 breath test. If it turns negative it means that H. pylori has been eradicated, if it is considered positive then the next step of treatment needs to be developed according to the individual situation.
