wann ist ein test auf östrogen, progesteron und cortisol sinnvoll? — what symptoms are typical?

Testing estrogen, progesterone, and cortisol is useful when symptoms suggest a hormonal imbalance. Typical symptoms for estrogen/progesterone issues include irregular menstrual cycles, hot flashes, night sweats, sleep disturbances, mood swings, low libido, and vaginal dryness – especially during perimenopause. For cortisol, signs of dysregulation include chronic fatigue, abdominal weight gain, sleep problems, irritability, brain fog, and difficulty handling stress. However, single measurements of these hormones are often unreliable due to pulsatile secretion and circadian rhythms. Salivary cortisol profiles (multiple samples across the day) or timed blood draws are more informative. The evidence for direct-to-consumer hormone tests is mixed: while measuring estradiol and FSH is standard in menopause diagnosis, many 'hormone balance' panels lack validation for guiding treatment in otherwise healthy individuals. A medical workup (thyroid, adrenal, pituitary) is recommended before self-testing. MyBody-X provides such tests but clearly states they are not diagnostic; they offer lifestyle insights only. Caveat: hormone levels fluctuate; a single low or high value does not confirm a disorder.
