There is no research data showing that probiotics can treat H. pylori infection. The full name of H. pylori is Helicobacter pylori, a specialized microorganism present in the stomach. Other than H. pylori, almost no other bacteria can survive in the strong acidic environment of the stomach, so taking any probiotic does not have an anti-H. pylori effect. Long-term H. pylori infection can cause gastritis, gastric ulcer and even stomach cancer. The treatment of H. pylori infection is currently based on a quadruple therapy, including two antibiotics, a proton pump inhibitor, a bismuth agent, the specific medication and the course of treatment need to follow the doctor’s instructions. Probiotics are not used in the treatment. In summary, the treatment of H. pylori infection needs to take the regular quadruple therapy, probiotics can not anti-H. pylori.
