Every year in Ireland, tens of thousands of fragility fractures occur — bones broken not by accidents or significant trauma, but by the kind of minor falls or bumps that a healthy skeleton should easily withstand. Behind nearly every one of these fractures is a condition called osteoporosis: silent, invisible, and extraordinarily common.
And yet, the vast majority of the estimated 300,000 to 500,000 people in Ireland who have osteoporosis do not know they have it. They have never had a bone density scan. They have never discussed their fracture risk with a GP. They are, in the language of public health, “undetected cases” — people carrying a serious condition without a diagnosis, without treatment, and without the opportunity to prevent the fractures that will eventually, for many of them, change the course of their lives.
Why Does Osteoporosis Go Undetected?
The answer starts with the nature of the disease itself. Osteoporosis is, by definition, asymptomatic. There is no pain. There is no visible change. There is nothing that feels wrong until a bone breaks — and even then, the fracture may be misattributed to the fall rather than to the underlying fragility of the bone.
This distinguishes osteoporosis from most other serious chronic conditions. Heart disease announces itself through chest pain and breathlessness. Diabetes triggers thirst and fatigue. High blood pressure, another “silent” condition, is routinely screened in GP surgeries without patients needing to request it. Osteoporosis, by contrast, requires a specific referral for a specific scan — and that referral only happens if someone thinks to ask, and if the GP judges it appropriate.
In many cases, neither the patient nor the GP raises bone health as a priority. Patients do not know they are at risk. GPs, under enormous time pressure in a primary care system that is chronically under-resourced, cannot proactively screen every patient who might benefit. And so the disease progresses, silently, until a fracture reveals what the absence of symptoms concealed.
Who Is Falling Through the Gaps?
The under-diagnosis of osteoporosis is not evenly distributed. It concentrates in certain groups:
Men are dramatically under-screened. While post-menopausal women are increasingly — if still insufficiently — associated with osteoporosis in clinical and public awareness, men remain largely invisible in the narrative. Yet one in five men over 50 will experience an osteoporosis-related fracture in their lifetime, and when they do, their outcomes are often worse than women's. Men who suffer hip fractures have a higher one-year mortality rate. They are less likely to be assessed after their fracture, less likely to receive treatment, and more likely to sustain a second fracture as a result.
Younger post-menopausal women — those in their early fifties who have recently gone through menopause — are in the period of most rapid bone loss, yet are often not referred for scanning unless they have additional risk factors. The decade immediately following menopause is, paradoxically, the window in which intervention is most effective and most frequently missed.
People on long-term corticosteroids — prescribed for conditions like asthma, rheumatoid arthritis, inflammatory bowel disease, and COPD — face significantly elevated fracture risk from their medication, yet bone protective measures are not always initiated automatically.
The First Fracture That Should Have Prompted Action
Perhaps the most preventable failure in the care of osteoporosis is what happens — or rather, what does not happen — after a first fragility fracture. A wrist fracture treated in an Emergency Department, cast applied, patient discharged. A vertebral fracture managed with painkillers and rest. A hip fracture repaired with surgery, patient rehabilitated and sent home. In each case, the fracture itself is treated. But the underlying osteoporosis — the reason the bone broke in the first place — goes unaddressed.
Research consistently shows that fewer than one in five people who sustain a fragility fracture receive a bone density scan afterwards. Fewer than one in ten are started on bone-protective medication. The evidence base for secondary fracture prevention is strong, the interventions are available, and yet the gap between what should happen and what does happen remains striking.
The consequence is a “fracture cascade”: a first fracture dramatically increases the risk of a second, which increases the risk of a third, each one typically more serious than the last. A wrist fracture that should have triggered bone density assessment and treatment instead becomes the first in a sequence that eventually includes a hip fracture — and all the mortality, loss of independence, and cost that follows.
What Needs to Change
At a systems level, the solution is well understood. Fracture Liaison Services (FLS) — specialist-coordinated programmes that automatically identify, assess, and treat fragility fracture patients — have been shown to dramatically increase the proportion of patients who receive appropriate bone health management after a fracture. Countries and healthcare systems with universal FLS coverage have significantly lower rates of secondary fractures. Ireland is expanding its FLS provision, but coverage remains incomplete.
At an individual level, the most important change is awareness. People need to know what osteoporosis is, what their risk factors are, and what to ask their GP. The evidence is clear: awareness drives earlier diagnosis, earlier diagnosis drives earlier treatment, and earlier treatment prevents fractures.
What You Can Do Now
If you are over 50 — or younger with significant risk factors — we would encourage you to speak to your GP about your bone health. Ask specifically whether a DXA scan (bone density test) would be appropriate for you. You can use our Risk Factors page to understand which factors apply to your situation.
If you have already had a fracture — even a wrist fracture that seemed minor — ask whether you have been assessed for osteoporosis. If not, ask for a referral. It is a reasonable and medically justified request. The fracture that seemed like a minor inconvenience may be telling you something important.
Osteoporosis is called the silent disease. But its consequences are anything but quiet. Earlier diagnosis and treatment can prevent those consequences — and it starts with a conversation.
