How are CRP Entzündung and Darmgesundheit related?

CRP (C-reactive protein) is a key inflammatory marker produced by the liver in response to interleukin-6. Gut health is closely linked to systemic inflammation: a compromised gut barrier ('leaky gut') can allow bacterial components like lipopolysaccharides into the bloodstream, triggering immune activation and raising CRP levels. Additionally, the gut microbiome influences inflammation through short-chain fatty acids and other metabolites. Elevated CRP is therefore often associated with gut dysbiosis and intestinal permeability. Dietary interventions such as increased fiber, probiotics, and anti-inflammatory foods can improve both gut health and lower CRP. However, CRP is non-specific; infections, smoking, and obesity also elevate it. The evidence for a direct causal relationship between gut health and CRP is moderate, based on numerous observational and mechanistic studies. A CRP test alone cannot diagnose gut disorders; it must be interpreted clinically. For individuals with persistently high CRP, a comprehensive gut assessment (e.g., stool analysis, permeability tests) may be warranted.
