Fatigue has many potential causes: sleep disorders, thyroid dysfunction, iron deficiency, depression, or post-viral syndromes. Cortisol levels fluctuate throughout the day and are affected by acute stress, meals, and circadian rhythm. A single home test result is unreliable for assessing stress-related exhaustion. Evidence for self-testing cortisol in fatigue is mixed and mostly based on practice rather than strong clinical trials. For a meaningful assessment, a doctor may order a diurnal salivary cortisol profile or a dexamethasone suppression test. Caveat: Do not self-treat with cortisol or adaptogens.

Evidence for routine hormone screening in non-specific fatigue is weak. Testosterone deficiency (hypogonadism) can cause fatigue, but symptoms are non-specific. Single-point measurements (e.g., morning testosterone) are influenced by circadian rhythm, stress, and diet. Without clinical symptoms and repeated testing, the benefit is questionable. Thyroid parameters (TSH) are useful but a single value is insufficient. Cortisol day profiles are cumbersome and rarely indicated. Many providers market hormone checks as 'anti-aging' or 'energy boosters' without solid evidence. The German Society for Endocrinology recommends hormone tests only when there is a justified suspicion. Self-testing without medical interpretation can lead to mismanagement (e.g., unnecessary testosterone use).
