How do I know if I have this — when the disease refuses to speak?
It refuses to speak — that is its nature. Bone loss is painless, invisible, and undetectable by feel; the first symptom is usually a fracture, often from a fall that shouldn't have broken anything. What this chapter really teaches is pattern recognition: the three classic fractures (wrist, spine, hip) at their three classic ages, the quiet signs (height loss, the rounding back), and the single most important habit in bone medicine — treating every fragility fracture as the diagnosis it probably is, not as an isolated accident.
Losing more than 2 cm on measurement — or 4 cm versus your young-adult height — suggests compressed vertebrae. The spine fractures silently, a millimeter at a time.
CommonKyphosis — the forward curve ('dowager's hump') — is stacked vertebral compression made visible. Often dismissed as 'just aging'; it is the disease in plain sight.
CommonA bone broken from a fall from standing height, a cough, or a hug. By definition, that bone was osteoporotic until proven otherwise — whatever the X-ray says about the cast.
CommonOne fracture predicts the next: a vertebral fracture raises future fracture risk 4–5 fold. The first break is the warning the disease never sent any other way.
CommonThe fractures arrive in a sequence that tracks the menopause timeline. The wrist typically goes first — the 50s and 60s — because a forward fall on outstretched hands finds the forearm's trabecular end. The spine follows through the 60s and 70s: compression fractures that are often painless or briefly painful, dismissed as 'a pulled muscle,' leaving two-thirds undiagnosed while the architecture stacks down. The hip is the event of advanced age — the fall from standing height onto a hip whose femoral neck lattice has thinned for thirty years. Each fracture site at its age is not coincidence; it is the disease's fingerprint.
Two patterns deserve special attention. First, the treatment gap: fewer than a third of people who suffer fragility fractures leave the hospital on osteoporosis treatment — the fracture is fixed, the disease is ignored, and the next one follows. Advocates call the fragility fracture 'the heart attack of osteoporosis' for exactly this reason: a sentinel event demanding treatment, not just repair. Second, secondary-cause screening: new osteoporosis in unexpected patients (young, male, premenopausal) or unusually aggressive loss warrants checking thyroid function, vitamin D, parathyroid hormone, celiac markers, and the medication list — glucocorticoids above ~5–7.5 mg prednisone daily for 3+ months being the classic prescription culprit.
