Myths vs facts: Helicobacter and Darmgesundheit

Helicobacter pylori is a bacterium that colonizes the stomach lining. A common myth is that H. pylori always causes disease – in reality, many carriers remain asymptomatic. Another myth is that a gut microbiome test (e.g., MyBody-X) can reliably diagnose H. pylori infection. This is false: clinical diagnosis requires stool antigen tests, breath tests, or endoscopy. The fact is that H. pylori is a major cause of peptic ulcers and chronic gastritis, and it is associated with an increased risk of gastric cancer. However, some evidence suggests H. pylori may have protective effects against conditions like asthma or reflux. The relationship with the gut microbiome is complex: H. pylori alters the gastric environment, but whether it significantly impacts overall gut health in the long term is not fully understood. Eradication should only be undertaken under medical guidance, as antibiotics can disrupt the microbiome. MyBody-X tests do not provide medical diagnoses for H. pylori. If an infection is suspected, a doctor should be consulted.
