Myths vs facts: Cardio Risk Check and Müdigkeit

Myths vs. Facts: Cardio Risk Check and Fatigue. A Cardio Risk Check (e.g., hs-CRP, lipids, blood pressure) can indicate inflammation or cardiovascular risk, but it does not directly explain fatigue. Fact: Fatigue is multifactorial – iron deficiency (ferritin), thyroid function (TSH), sleep quality, stress, and nutrition play larger roles. Myth: A single test like hs-CRP or a lipid panel can reveal the cause of exhaustion. Evidence shows hs-CRP correlates with inflammation but is not causal for fatigue. Ferritin self-tests are only orienting and can be falsely elevated by inflammation. A TSH home test does not provide a diagnosis. Conclusion: Cardio risk markers are useful for prevention, but not as a standalone explanation for fatigue. For persistent tiredness, a medical workup with complete blood count, iron status, thyroid panel, and lifestyle assessment is recommended. The evidence for direct links between these markers and fatigue is weak to moderate; most home tests are marketing-oriented without clinical validation.
