Is CRP Entzündung useful for Müdigkeit?

CRP (C-reactive protein) is a non-specific marker of inflammation. Elevated levels can indicate systemic inflammation, which may be linked to fatigue and tiredness in conditions like chronic infections, autoimmune diseases, or low-grade chronic inflammation. However, CRP is not a direct measure of fatigue itself. Many individuals with fatigue have normal CRP, and many with elevated CRP do not report fatigue. The evidence for a causal link is moderate: observational studies show associations between higher CRP and fatigue in certain populations (e.g., chronic fatigue syndrome, fibromyalgia), but effect sizes are small and clinical utility is limited. A CRP test can be useful as part of a broader workup to rule out inflammatory causes, but it should not be used in isolation to diagnose or manage fatigue. MyBody-X offers CRP as a biomarker, but interpretation requires a physician. Caution: a normal CRP does not exclude inflammation-related fatigue, and a mildly elevated CRP can result from benign factors like stress, poor sleep, or minor infections. Always consider lifestyle and other clinical findings.
