Do all H. pylori infections require treatment? H. pylori infects more than half of the world’s population, but the outcomes of infection vary widely, with only a small percentage developing peptic ulcers and a very small number progressing to gastric cancer. Therefore not all infected people need to be treated with medication. Our experts developed a consensus opinion on the treatment of H. pylori in 2007. The following are summarized: 1. The following conditions must be treated: peptic ulcer, early postoperative gastric cancer, gastric MALT lymphoma, chronic gastritis with gastric mucosal atrophy and erosion; 2. Patients with unexplained iron deficiency anemia, patients with idiopathic thrombocytopenic purpura (ITP), other H. pylori-related gastric diseases, and patients who strongly request treatment for various reasons. It is important to remember that H. pylori is not the only factor causing your various gastric symptoms, which means that even if you eradicate H. pylori, your symptoms may not be completely relieved and in many cases a combination of treatments is needed. How to treat H. pylori infection A variety of antibiotics, acid suppressants and bismuth agents are used clinically for the treatment of H. pylori infection. Commonly used are triple therapy: 1 PPI (esomeprazole, omeprazole, lansoprazole, pantoprazole, rabeprazole) or bismuth (bismuth potassium citrate, bismuth pectin, etc.) + 2 antibiotics (usually amoxicillin + clarithromycin or metronidazole or furazolidone, etc.); quadruple therapy: any one PPI + bismuth + 2 antibiotics; 7-14 days of treatment. The above are only commonly used reference programs, specific patient conditions require specific analysis by doctors. In summary, we can say that H. pylori can be prevented and treated is not terrible, the most important thing is to go to a regular hospital to receive regular treatment by a specialist.
