'Tired' isn't a diagnosis

Stop 1/5

累不是诊断 · 4 个层次

'Tired' is one of medicine's most non-specific symptoms — the same word covers several layers of different problems. The atlas pulls that line apart for the first time.

Layer 1 · Normal physiological fatigue

Sleep deprivation + exercise + work stressRecovers with restNo medical evaluation needed
Layer 2 · Persistent fatigue (<6 months)

'Slept 8 hours and still tired' for weeksUsually has a trigger (acute illness, stress, season)Mostly self-limited; recovers after nutritional or psychological improvement
Layer 3 · Chronic fatigue (>6 months)

Persistent for more than 6 monthsMultifactorial: combinations of sleep disorder + nutrition + endocrine + psych + chronic diseaseRequires systematic evaluationMost cases reveal one or more reversible causes
Layer 4 · ME/CFS (Myalgic Encephalomyelitis / Chronic Fatigue Syndrome)

A separate disease, not 'a severe version of fatigue'Core: PEM (post-exertional malaise) — the most important distinction from ordinary chronic fatigueDiagnosis IOM 2015 + NICE 2021: exclusion plus 4 required criteria~0.4% global prevalence; severely affects functionHigh overlap with Long COVID (next step)
Why give it a dedicated atlas island?

'Tired' is one of the most commonly misdiagnosed or ignored chief complaintsADHD, anxiety, depression, hypothyroidism, OSA, and iron deficiency are routinely dismissed as 'just tired'The market's 'anti-fatigue supplement' grab-bag — adaptogens, high-dose B vitamins, injections — does not address root causesThe correct path is systematic differential plus individualized treatment, which matters more than selling any 'energy supplement'
