Myths vs facts: Helicobacter and Schlaf

The claim that Helicobacter pylori infection directly causes sleep disturbances is not well-supported by robust evidence. Some small studies suggest a possible link via chronic inflammation, dysbiosis, or the gut-brain axis (e.g., increased cytokines or reflux symptoms). However, these are mostly correlational and lack controlled trials. Many individuals with H. pylori have normal sleep, and conversely, poor sleep or stress can worsen gastric symptoms. A breath or stool test can confirm infection, but eradication therapy is only recommended for symptomatic cases or high-risk groups (e.g., peptic ulcer, family history of gastric cancer). If you experience frequent nighttime awakenings or heartburn, consult a gastroenterologist rather than self-testing for H. pylori. The overall evidence is mixed and inconclusive.
