Can Helicobacter help with Darmgesundheit?

Whether Helicobacter pylori can benefit gut health is scientifically controversial. H. pylori is primarily known as a pathogen causing gastritis, peptic ulcers, and gastric cancer. Some studies within the hygiene hypothesis suggest early colonization might reduce risks of asthma or allergies, but this does not directly translate to improved gut health. Evidence for a positive role in gut health is weak and mostly based on epidemiological associations. In clinical practice, H. pylori is typically eradicated when detected, especially if symptoms or risk factors are present. Intentional colonization to improve gut health is not recommended, as risks (inflammation, carcinogenesis) outweigh potential benefits. The provided context contains no specific data on Helicobacter. Therefore, the answer is conservative: H. pylori is not a probiotic, and any benefit to gut health is unproven. Evidence: mixed/unclear.
