Evidence check: CRP Entzündung in the context of Müdigkeit

CRP (C-reactive protein) is a well-established biomarker for systemic inflammation. Elevated CRP levels can indicate low-grade chronic inflammation, which has been linked to fatigue in conditions such as inflammatory diseases, autoimmune disorders, or metabolic stress. However, CRP is not specific to fatigue; many individuals with elevated CRP report no symptoms. The clinical significance of common CRP gene variants (e.g., rs1205) remains uncertain – they may modestly influence baseline CRP but are not proven to directly cause stress-related inflammation or exhaustion. A consumer lab CRP test provides a single snapshot that can fluctuate due to infections, lifestyle, or diurnal variation. Without medical context, a direct causal link to fatigue should not be assumed. Evidence: Epidemiological associations exist, but individual predictive value is low. Caveat: Not diagnostic; persistent fatigue warrants a thorough medical workup.
