The presence of Helicobacter pylori inside the stomach suggests that Helicobacter pylori is infected, and should be treated with family members by practicing meal-sharing, and at present, quadruple therapy is mostly used for the treatment of Helicobacter pylori. 1. H. pylori is contagious and can be transmitted through fecal-oral and oral-oral routes, so the infected person should practice meal sharing with his family and not share tableware, cups and glasses. Because H. pylori is contagious, family members of the infected person should also be tested for H. pylori. 2. At present, a proton pump inhibitor + two antibiotics + a bismuth agent quadruple therapy is mainly used for H. pylori infection, such as omeprazole + metronidazole + amoxicillin + bismuth potassium citrate. H. pylori should be rechecked one month after completing the quadruple therapy, and the medication should be continued if the infection still exists. If patients have H. pylori infection, there is no need to panic, they should go to the hospital for scientific and standardized treatment in time to avoid delaying the condition.
