What role does Helicobacter play in sleep?

The provided context does not address the role of Helicobacter (H. pylori) in sleep. Generally, a possible link is discussed via the gut-brain axis and inflammatory pathways, but evidence is weak and inconsistent. Some studies suggest associations with sleep disorders such as obstructive sleep apnea or restless legs syndrome, but causal evidence is lacking. Clinical relevance remains unclear, and H. pylori eradication alone is not recommended for sleep improvement. Further research is needed to confirm potential mechanisms (e.g., via serotonin or melatonin pathways).
