Osteoporosis: The Condition You Cannot Feel Until It Breaks

Most conditions announce themselves. Something aches, something changes, and eventually someone books an appointment.

Osteoporosis does not do this. Bone loss produces no pain, no stiffness and no detectable change in how you feel, from the day it begins until the day something breaks. By the time there is a symptom, the disease has been present for years and the symptom is a fracture.

That single fact determines everything about how it should be managed. A condition with no early warning is either measured or it is missed. There is no third option.

What is actually happening

Bone is not inert scaffolding. It is living tissue in constant turnover, with cells dissolving old bone and others laying down new. Through early adulthood the balance favours building. Peak bone mass is reached in the late twenties, and everything afterwards is a question of how slowly you draw down the account.

The drawdown is normally gradual. Two things change that.

The menopausal transition. Oestrogen restrains bone resorption, and when it falls, resorption accelerates. Loss is fastest in the years immediately surrounding the final period, which is why that window matters more than any other, and why it is the point at which a baseline measurement is worth most. Our article on the menopausal transition covers the wider picture.

Everything else that compounds it. Long-term corticosteroid use, low body weight, smoking, heavy alcohol intake, prolonged inactivity, inadequate protein or calcium, vitamin D deficiency, and several chronic conditions including inflammatory disease and untreated coeliac disease.

Men are not exempt. Bone loss in men is slower and starts later, but male fractures carry worse outcomes on average, partly because the diagnosis is so rarely considered until it is too late.

The Malaysian problem with screening shortcuts

This is the part that is not in the international articles, and it matters here.

Because bone density scanning is not universally available or affordable, several simplified tools exist to identify who most needs one. The two in common use are FRAX, which estimates ten-year fracture probability from clinical risk factors, and OSTA, the Osteoporosis Self-Assessment Tool for Asians, which uses only two inputs, age and body weight.

OSTA is appealing precisely because it is simple, and it was developed using data from postmenopausal women across eight Asian countries. It has been widely adopted across the region.

But a Malaysian study found OSTA unsuitable for identifying osteoporosis in Malaysian postmenopausal women.

The likely reason is population composition. Validation work drew heavily on Chinese populations, and a Singaporean study, in a population that is roughly three-quarters Chinese, found FRAX and OSTA performing comparably. Malaysia is a different country demographically, with Bumiputera including Malay populations forming around seventy per cent. A tool calibrated on one population does not automatically transfer to another, and in this case it appears not to have.

The practical consequence for you: if you have been reassured by a quick risk-score calculation rather than a measurement, that reassurance may be worth less here than the tool's popularity suggests. This is the same problem as the Asian BMI thresholds in a different guise, which is that instruments calibrated elsewhere need local validation before they are trusted.

What the measurement actually tells you

DXA, dual-energy X-ray absorptiometry, remains the reference standard. It is quick, uses a very small radiation dose, and typically measures the hip and lumbar spine.

The result is reported as a T-score, comparing your bone density against that of a healthy young adult:

Two points about interpretation that are commonly missed.

Osteopenia is not a mild disease. It is a description of where you sit on a continuum, and because far more people have osteopenia than osteoporosis, a substantial share of fractures occur in that range. It is a reason to act, not a reason to relax.

FRAX and DXA are better together than either alone. Fracture risk predicted by clinical factors alone and by bone density alone are broadly similar in accuracy, and combining them outperforms both. A number without context is a weaker instrument than it appears.

How often should it be repeated?

More rarely than people assume, and the interval depends heavily on the first result.

The US Preventive Services Task Force found no clear advantage to repeating bone density measurement between four and eight years after an initial normal screen. A Korean study following women over fifty found the interval to developing osteoporosis differed dramatically by starting point: a baseline T-score around -1.4 corresponded to roughly thirteen years, while around -1.6 corresponded to about five.

Which is a useful thing to know before paying for annual scans. The first measurement is the one that carries the information. It tells you where you are and how often you need to look again, and for many people the answer is not soon.

The honest bit

Screening is genuinely contested. Reasonable clinicians disagree about who should be scanned and when, and guidelines differ between countries. What is not contested is that the condition is silent, that fractures carry serious consequences, and that risk rises steeply with age.

The tools were built elsewhere. FRAX has versions calibrated for different populations, and concerns have been raised about the validity of race-specific calibration generally. OSTA appears not to transfer to the Malaysian population. This does not make either useless; it makes them tools requiring judgement rather than calculators producing verdicts.

Not every low reading needs treatment. A T-score is one input alongside age, fracture history, family history and other risk factors. The decision to treat is separate from the decision to measure, and conflating them causes both over-treatment and under-treatment.

And prevention has a deadline that has partly passed. Peak bone mass is set by the late twenties, and adolescence is when most of it is laid down. That opportunity does not reopen. What remains available is slowing the loss, which is worth doing and is genuinely effective, but it is a different task from building.

What actually protects bone

Resistance and impact training. The strongest modifiable lever available. Bone responds to mechanical load, and it responds specifically at the sites loaded, which is why weight-bearing exercise beats swimming and cycling for this purpose despite their other merits. Two to three resistance sessions a week, progressively loaded. This is the same prescription that protects muscle, and the two conditions travel together, as covered in protein and muscle after 40.

Protein. Bone is roughly half protein by volume, and adequate intake supports both bone and the muscle that loads it. Insufficient protein is a common and correctable problem in older adults.

Calcium, preferably from food. Dairy, calcium-set tofu, small fish eaten with bones such as ikan bilis, dark leafy greens, and fortified alternatives. Supplements have a role where intake genuinely cannot be met, and are not a first resort.

Vitamin D, which needs measuring here. Deficiency is common in Malaysia despite the sunshine, for entirely explicable reasons: indoor work, deliberate sun avoidance, and covered clothing. Calcium absorption depends on it, so it is worth testing rather than assuming.

And the things that erode it: smoking, heavy alcohol use, prolonged sedentary periods, and repeated crash dieting, which costs bone as well as muscle.

Who should be measured

• Women in the years around and after the final menstrual period, which is when loss is fastest and a baseline is worth most
• Anyone over 65, and men over 70, where most guidelines recommend measurement irrespective of other risk factors
• Anyone with a fragility fracture, meaning a break from a fall at standing height or less, at any age. This is diagnostic in itself and too often treated as bad luck
• Long-term corticosteroid users, and people with conditions or medications known to affect bone
• Anyone with a parental hip fracture, low body weight, or early menopause
• Anyone whose weight has fallen substantially, deliberately or otherwise

At Hayat Longevity, bone health is reviewed as part of the assessment, with onward referral for bone density measurement where indicated, alongside body composition, protein intake and the training programme that determines whether bone is loaded at all. The pre-consultation questionnaire covers the history that determines whether this applies to you.
