Evidence check: CRP Entzündung in the context of gut health

CRP (C-reactive protein) is a non-specific inflammatory marker produced in the liver, rising during systemic inflammation. In the context of gut health, elevated CRP may indicate inflammatory bowel disease (e.g., Crohn's disease, ulcerative colitis) or increased intestinal permeability ('leaky gut'). However, CRP is not gut-specific – infections, autoimmune conditions, or obesity can also raise levels. MyBody-X DNA tests do not measure current CRP; they analyze genetic variants (e.g., in IL6, TNF) that may influence inflammatory tendency. The evidence linking these variants directly to gut-related CRP elevation is weak to moderate. Clinically relevant CRP should always be measured via blood test. A DNA test cannot diagnose acute inflammation. Persistent gut symptoms with elevated CRP require medical evaluation.
