What role does Helicobacter play in Müdigkeit?

Helicobacter pylori (H. pylori) is primarily known for causing gastritis and peptic ulcers, but its link to fatigue is indirect and not always straightforward. Chronic H. pylori infection can lead to atrophic gastritis, impairing vitamin B12 absorption – deficiency of B12 causes fatigue and neurological issues. Additionally, the infection can cause iron deficiency anemia through chronic inflammation or occult bleeding, both of which result in tiredness. However, many infected individuals remain asymptomatic. Direct-to-consumer DNA tests for H. pylori are not standard; MyBody-X does not include such analysis. Diagnosis relies on stool antigen or breath tests. The evidence for a causal role of H. pylori in fatigue is moderate: observational studies show associations, but robust randomized trials are lacking. Fatigue workup should prioritize more common causes (thyroid, sleep apnea, depression). Treating H. pylori solely for fatigue is not recommended unless gastrointestinal symptoms or confirmed deficiency are present. In summary, H. pylori can contribute to fatigue via anemia or B12 deficiency, but it is rarely the sole cause.
