Evidence check: Hormoncheck Frauen in the context of Müdigkeit

The question of a hormone check for women experiencing fatigue is valid, but the evidence is nuanced. Fatigue can stem from many causes—sleep deprivation, stress, iron deficiency, or thyroid dysfunction. A hormone check (e.g., TSH, fT3, fT4, cortisol, estradiol, progesterone, testosterone) can be useful when specific symptoms or risk factors are present. However, the evidence for broad hormone screening in unexplained fatigue without clinical clues is weak. Many direct-to-consumer hormone tests promise more than they deliver. Results are often difficult to interpret because hormone levels fluctuate with circadian rhythm and menstrual cycle. Moreover, clear clinical reference ranges are lacking for many offered biomarkers (e.g., DHEA, melatonin). Targeted testing of thyroid function (TSH) and iron status (ferritin) is evidence-based and recommended for fatigue. In suspected menopause, measuring FSH and estradiol can be helpful, but symptoms guide the diagnosis. Bottom line: A hormone check is not a magic bullet. Seek medical advice before purchasing expensive home tests. Evidence: human-moderate (for targeted parameters), for broad panels rather marketing.
