Myths vs facts: Helicobacter and Allergie

The relationship between Helicobacter pylori and allergies is complex and often misunderstood. A common myth is that H. pylori infection causes or worsens allergies. In fact, some studies suggest H. pylori may even protect against certain allergies (hygiene hypothesis), while others find no link or an increased risk. The evidence is conflicting and insufficient for a clear conclusion. Importantly, H. pylori testing (e.g., stool or breath test) is used to diagnose gastric infection, not to assess allergies. Treating the infection does not improve allergic symptoms based on current data. If allergies are suspected, specific allergy tests (e.g., IgE measurement) are recommended. In summary, the connection is not scientifically established; individual factors like genetics, environment, and microbiome play a larger role. MyBody-X does not offer specific H. pylori tests; for allergies, blood or skin tests by a physician are advisable.
