What role does Stuhlprobe play in Schlaf?

A stool test (microbiome analysis) examines the composition of gut bacteria. Through the gut–brain axis, gut microbes can influence sleep: they produce neurotransmitters such as serotonin (a melatonin precursor) and GABA, which modulate sleep–wake cycles. Dysbiosis has been linked to poorer sleep quality, difficulty falling asleep, and increased inflammation. However, the evidence is mostly observational; randomized trials with probiotics show mixed results. A MyBody-X stool test may reveal individual patterns, but it cannot diagnose a sleep disorder. Clinical utility is limited – lifestyle, diet, and stress management have a far greater impact on sleep. Safety note: the stool test is non‑invasive and risk‑free. Interpretation should be done by a physician or nutrition specialist.
