The main reason for this is that bacterial gastritis can be transmitted to each other. It is believed that bacterial gastritis is mainly caused by H. pylori infection, and this gastritis can be transmitted to each other by sharing meals or utensils. If the presence of H. pylori infection is detected, it is recommended that active anti-H. pylori treatment is recommended, mainly quadruple therapy, an acid-suppressing drug, a bismuth agent, combined with two antibiotics, can also add a probiotic to increase the eradication rate and reduce adverse reactions. The addition of antibiotics to anti-H. pylori drugs can cause serious adverse reactions in patients, which can include abdominal pain, nausea, vomiting, and diarrhea. After patients add probiotics, the adverse reactions can be significantly reduced and the eradication rate of H. pylori is improved, and the course of treatment is recommended for a period of 10-14 days. Once H. pylori infection is detected, eating must be separate utensils and pay attention to regular re-examination.
