Is Cortisol senken useful for Darmgesundheit?

The question of whether lowering cortisol benefits gut health is scientifically plausible but evidence is limited. Chronically elevated cortisol – e.g., from persistent stress – can impair the gut barrier („leaky gut“), alter microbiota composition, and promote inflammation. Observational studies link psychological stress to irritable bowel syndrome and inflammatory bowel disease. However, no robust randomized controlled trials directly prove that lowering cortisol (via lifestyle or pharmacological means) improves gut health. Most data come from animal models or correlational human studies. Cortisol is essential for metabolism and immune function; excessive suppression can cause adrenal insufficiency. For healthy individuals, stress reduction and adequate sleep are reasonable, but targeted cortisol lowering as a gut health intervention lacks evidence. Caution: at-home cortisol tests (saliva, blood) show high variability and should not be used for self-diagnosis.
