Carbon 13 positive often suggests that for Helicobacter pylori present infection, whether good treatment depends on the severity of the patient’s own disease, generally after standardized eradication of Helicobacter pylori drug treatment, can be cured, but if the patient does not pay attention to hygiene and living habits, will be re-infected. The common clinical drug treatment program is quadruple therapy, a proton pump inhibitor (such as omeprazole, lansoprazole, pantoprazole, etc.) + bismuth (such as colloidal bismuth subcitrate, etc.) + two antibiotics (such as Amoxicillin + Clarithromycin, Amoxicillin + Metronidazole, Tetracycline + Furazolidone, etc.), a combination of medication to control the condition, and the four-conjugate program of the course of treatment is generally 14 days. Through standardized treatment, H. pylori infection can be cured, but re-infection can occur if hygiene and lifestyle habits are not observed. If carbon 13 positive, it is recommended to follow the doctor’s instructions and apply the drugs rationally when using medication to avoid causing serious adverse reactions.
