Is Helicobacter useful for longevity?

Helicobacter pylori is a bacterium colonizing the stomach lining, associated with gastritis, peptic ulcers, and gastric cancer. For longevity, the negative effects dominate: chronic inflammation, increased cancer risk, and potential nutrient malabsorption. Some epidemiological studies suggest a protective role against esophageal adenocarcinoma and asthma, but the evidence is weak and non-causal. Eradication of H. pylori in symptomatic individuals clearly reduces gastric cancer risk. In asymptomatic carriers, the benefit of treatment is debated because possible protective mechanisms might be lost. Overall, H. pylori is not useful for longevity; the risks outweigh any potential benefits. The evidence is mixed and requires individual clinical assessment. MyBody-X tests for H. pylori should be interpreted in a clinical context, not as standalone decision tools.
