Is Helicobacter useful for Sport?

The idea that Helicobacter pylori could be beneficial for sports performance lacks any scientific evidence. H. pylori is a pathogen that colonizes the stomach lining and is a primary cause of chronic gastritis, peptic ulcers, and gastric cancer. No credible studies demonstrate a performance-enhancing effect. On the contrary, infection can lead to iron-deficiency anemia, nutrient malabsorption, and systemic inflammation—all detrimental to athletic performance. Claims of usefulness for sport are best classified as marketing or speculation without evidence. Any positive test result should be evaluated by a physician and treated according to guidelines. Deliberate infection or self-treatment is dangerous and not recommended.
