welche blutwerte sind wichtig bei müdigkeit — what can you do yourself?

The provided context does not directly address which blood values are important for fatigue. In general, common lab tests for unexplained fatigue include iron/ferritin, vitamin B12, vitamin D, thyroid function (TSH, fT3, fT4), and a complete blood count. However, the evidence for routine testing in all fatigue cases is mixed; many cases are lifestyle-related. What you can do yourself: improve sleep hygiene, manage stress, eat a balanced diet rich in iron and B vitamins, stay hydrated, and exercise moderately. If fatigue persists, consult a doctor for targeted lab work. The answer here is based on general medical practice, not on the provided knowledge snippets.
