Osteoporosis Prevention Guide for Adults Over 40

In 2019, an estimated 3.775 million people in the UK had osteoporosis, and there were about 527,000 new fragility fractures, equivalent to roughly 1,444 each day. Those figures come from the International Osteoporosis Foundation’s UK scorecard. They describe estimates for 2019, not a live count, but they show why prevention and early risk assessment matter.

Osteoporosis can develop without pain or an obvious change in fitness. A runner, cyclist or regular gym-goer may feel well while bone mineral density is falling, and the first clear sign can be a fracture after a fall from standing height or less. That does not mean every adult over 40 needs a scan. Prevention combines sensible exercise and nutrition with a risk-based clinical assessment when personal circumstances make one appropriate.

This guide explains how bone changes with age, which risks you can influence, what FRAX and DEXA can and cannot tell you, and when to seek medical advice. It is written for UK adults, but individual decisions still depend on age, sex, menopause status, fracture history, health conditions and medicines.

Why Osteoporosis Prevention Matters Long Before a Fracture

Bone mineral density, or BMD, is one important part of bone strength. It is not the whole story. Bone structure, age, previous fractures, falls, medical conditions and some medicines also affect the chance that a future impact will cause a fracture. The current National Osteoporosis Guideline Group overview therefore treats BMD as a major risk factor within a wider fracture-risk assessment, rather than as a pass or fail result on its own.

Osteoporosis is often called a silent condition because low bone density itself may not cause symptoms. Back pain, height loss or a change in posture can sometimes reflect vertebral fractures, but people should not wait for these signs before discussing clear risk factors. A fracture after a minor fall, a suspected vertebral fracture or sudden severe back pain deserves prompt clinical assessment.

The gap between fracture and diagnosis can be long. In written evidence submitted to Parliament in 2023, the Royal Osteoporosis Society reported that 38% of people waited more than a year after their first broken bone for a diagnosis, while almost one in five waited more than five years. The same submission said 90,000 people each year were missing treatment they needed and put the annual UK health and social care cost at £4.5 billion. These figures are claims from the Society’s submission, not a current NHS dashboard, but the UK parliamentary written evidence supports each number and illustrates the consequences of missed secondary prevention.

Fracture liaison services are designed to reduce that gap. They identify people after a fragility fracture, assess bone and falls risk, investigate possible underlying causes and arrange treatment where indicated. If you have already had a low-trauma fracture, prevention is no longer just a lifestyle question. It is a reason to ask whether a fracture liaison service, GP or specialist has reviewed your future risk.

The practical aim is not to chase a perfect scan number. It is to reduce avoidable fractures while keeping movement, strength and independence.

How Bones Stay Strong and Why They Weaken With Age

Bone is living tissue. Cells called osteoclasts remove older or damaged bone, while osteoblasts form new bone. This remodelling helps the skeleton respond to everyday loading and repair small areas of damage. During childhood and early adulthood, formation supports the development of peak bone mass. Later, the balance can shift so that more bone is removed than replaced.

Ageing is only part of that shift. Menopause, prolonged undernutrition, low body weight, physical inactivity, smoking, higher alcohol intake, some illnesses and some medicines can all alter bone health or fracture risk. Genetics and earlier-life bone development also matter, so two people with similar routines may not begin midlife with the same reserve.

The bank-account analogy is useful if it is not taken literally. Exercise and adequate nutrition support the conditions in which bone can be maintained, but they cannot guarantee that every withdrawal is replaced or reverse established osteoporosis. A person at high fracture risk may need medical treatment as well as lifestyle measures.

The three deposits that matter

Mechanical loading gives bone a reason to adapt. Weight-bearing activity loads the skeleton through the feet and legs. Resistance exercise adds force through muscle contractions. The response depends on the site, type and intensity of exercise, so swimming and cycling can be excellent for cardiovascular fitness without giving the same skeletal stimulus as suitable impact or resistance work.

Nutrition supplies the materials needed by bone and supporting muscle. Calcium is a major component of bone mineral, vitamin D supports calcium absorption and protein contributes to both bone and muscle tissue. More is not automatically better. Supplements can be inappropriate in some medical circumstances, and a restrictive diet may need review by a registered dietitian rather than a generic target from the internet.

Hormonal and medical context affects the remodelling balance. Falling oestrogen around menopause can accelerate bone loss. Low sex-hormone levels for other reasons, prolonged low energy availability, endocrine or digestive disease, and oral glucocorticoid treatment can also matter. Do not stop or change a prescribed medicine because it appears on a risk list. Ask the prescriber to review its benefits, risks and any need for bone protection.

Osteopenia is a signal, not a verdict

The term osteopenia is still widely used, although low bone mass or low bone density is often clearer. It usually describes a central DEXA T-score below the young-adult reference range but above the osteoporosis threshold. It does not mean that a fracture is inevitable, and it does not by itself show whether medicine is needed.

The reverse is also important. Many fragility fractures occur in people whose femoral-neck T-score is above the osteoporosis threshold. A previous fracture, age, falls, family history and medical factors can make risk clinically important even when the scan does not show osteoporosis. The International Society for Clinical Densitometry’s official positions distinguish diagnostic classification from fracture-risk assessment and state that people with low bone mass are not necessarily at high fracture risk.

Treat the result as one input to a decision. Ask which skeletal site was measured, which reference group was used, whether the scan was technically reliable and how the number changes your overall fracture-risk assessment.

Who Is Most at Risk and What You Can Change

Risk factors are not all equivalent, and an online checklist cannot calculate an individual’s probability reliably. The current NOGG fracture-risk guidance identifies previous fragility fracture, parental hip fracture, low body mass index, smoking, higher alcohol intake, oral glucocorticoids, rheumatoid arthritis and several secondary causes among the factors that can affect assessment. Falls and medicines that cause dizziness can add risk through a different route.

Some factors cannot be changed, but they can change what should happen next:

• Age and sex: Fracture risk generally rises with age, and the change in oestrogen after menopause can accelerate bone loss.
• Previous fracture: A low-trauma fracture is an important predictor of another fracture and should prompt clinical review.
• Family history: A parental hip fracture is specifically included in FRAX.
• Early menopause or low sex-hormone levels: These can reduce the protection that sex hormones provide to bone.
• Long-term health conditions: Malabsorption, inflammatory disease, endocrine disorders, kidney disease and other conditions may affect bone directly or through treatment.
• Medicine exposure: Oral glucocorticoids are a recognised risk. Other medicines may affect bone, balance or both, but any change needs prescriber-led review.

The protected 2024 UK clinical guideline reports that, among UK adults aged 50 or older, the estimated prevalence of a femoral-neck BMD T-score of -2.5 or lower was 6.8% in men and 21.8% in women. Those are sex-specific population estimates for one skeletal site, not the chance that a particular person has osteoporosis. The guideline applies its main assessment pathway to postmenopausal women and men aged 50 or older. An adult aged 40 to 49 may still need assessment when a fragility fracture, premature menopause, prolonged glucocorticoid use or another strong risk factor is present.

Factors you can influence

The useful question is not whether every risk can be removed, but which modifiable factors deserve attention now.

• Activity: Include regular weight-bearing activity and muscle-strengthening exercise, adapted to your ability and fracture risk.
• Smoking: Stopping smoking benefits bone and wider health. Ask for cessation support if needed.
• Alcohol: Keep intake within UK low-risk guidance and avoid patterns that worsen balance, nutrition or medicine safety.
• Food and energy availability: Aim for a balanced diet with adequate calcium, vitamin D, protein and total energy. Repeated aggressive dieting can be particularly concerning in adolescents, pregnancy, frail older adults, athletes at risk of low energy availability and anyone with an eating-disorder history.
• Falls: Address impaired vision, unsuitable footwear, trip hazards, loss of strength and balance, dizziness and medicines that may contribute to falls.
• Clinical follow-up: Attend reviews after a fragility fracture and take the complete medication list, including over-the-counter products.

A short self-check can help you prepare for a GP appointment:

1. Have you broken a bone after a fall from standing height or less?
2. Have you lost height, developed a more rounded upper back or experienced sudden back pain?
3. Did menopause occur early, or have periods stopped unexpectedly outside pregnancy?
4. Are you taking oral steroids or another medicine that a clinician has said may affect bone?
5. Do you have a condition that affects hormone levels, nutrient absorption, kidneys, inflammation or mobility?
6. Have you fallen, felt increasingly unsteady or become less able to rise from a chair?
7. Have you lost weight unintentionally or spent a prolonged period eating too little for your activity?

A yes does not diagnose osteoporosis. It identifies information worth discussing with a qualified healthcare professional.

Understanding Screening and What Your DEXA Results Mean

UK assessment is risk based rather than a universal scan programme for everyone over 40. FRAX combines age, sex and clinical risk factors to estimate the 10-year probability of hip fracture and major osteoporotic fracture. Femoral-neck BMD can be added when available. FRAX does not capture every relevant factor or its severity, so the result still needs clinical judgement.

NOGG recommends FRAX assessment for postmenopausal women and men aged 50 or older who have a clinical risk factor. People at intermediate risk are generally considered for BMD measurement to refine the estimate. At high or very high risk, BMD can help guide treatment choice and provide a monitoring baseline, but urgent treatment after some fractures should not be delayed simply to obtain a scan.

FRAX is not a diagnosis and is not interchangeable with QFracture. If a calculator produces a percentage, ask which fracture outcome and time period it describes, which country model was used, whether BMD was included and how the result compares with the relevant UK intervention threshold.

What happens during DEXA

DEXA, also written DXA, stands for dual-energy X-ray absorptiometry. It uses low-dose ionising radiation to estimate areal BMD. A diagnostic central examination usually measures the hip and lumbar spine. A whole-body protocol can report bone mineral content, fat mass and lean soft tissue, but it is not a substitute for a site-specific osteoporosis assessment.

You lie still on a scanning table while the arm passes over the relevant area. The procedure is non-invasive, but it remains a medical exposure. Tell the operator about possible pregnancy, recent contrast or barium studies, relevant implants and anything that may affect positioning. Degenerative change, artefacts and inconsistent positioning can alter interpretation, particularly at the spine.

The UK government position published on 30 March 2026 permits DEXA for named medical purposes, including osteoporosis diagnosis, fracture-risk assessment and treatment monitoring. It states that non-medical DEXA for sports performance, general body-composition analysis, fitness profiling and wellness is not justified and is prohibited. A public consultation does not change the current position while its outcome is pending.

Under IR(ME)R guidance, an entitled practitioner must justify each individual exposure before it occurs. That decision considers the medical objective, the person’s characteristics, likely benefit and detriment, relevant medical information and whether a non-ionising or lower-radiation alternative could answer the question. Pregnancy status is considered where relevant.

Where there is a permitted medical purpose, Telomyx’s medically governed DEXA service follows individual practitioner justification rather than offering scans solely for curiosity, aesthetics, sports profiling or general wellness. The source also contains a protected catalogue link labelled Demo DEXA Scan. That link currently redirects to a product page, but a catalogue entry does not establish a lawful indication or show that an exposure is appropriate for an individual.

For more detail on the difference between central and whole-body protocols, read the Telomyx guide to BMD and DEXA scanning.

Reading T-scores and Z-scores

A T-score compares BMD with a young-adult reference. A Z-score compares it with a reference population of similar age and sex, with population-specific reference data used where available. They answer different questions.

Score and population	Result	What it means
T-score in postmenopausal women and men aged 50 or older	-1.0 or above	Within the normal densitometric range
T-score in the same groups	Below -1.0 but above -2.5	Low bone mass, often called osteopenia
T-score in the same groups	-2.5 or lower	In the densitometric osteoporosis range at a valid diagnostic site
Z-score in premenopausal women and men under 50	-2.0 or lower	Below the expected range for age and may prompt investigation for secondary causes

These categories do not replace clinical assessment. T-scores are used at valid central sites within the appropriate population. Z-scores are generally preferred before menopause and in men under 50, and osteoporosis should not be diagnosed in a man under 50 from BMD alone. A fracture can also be clinically important when the T-score is above -2.5.

Read the full report rather than the lowest number in isolation. Check the site, scan quality, reference database and clinical interpretation. Hip and spine values can differ, and degenerative change can make a spine result look artificially high. When comparing scans, the observed change needs to exceed the facility’s calculated least significant change before it can confidently be separated from measurement variability.

Evidence Based Exercise and Nutrition for Stronger Bones

Exercise supports bone, muscle and balance, but the plan should match the person. The NOGG non-pharmacological guidance recommends a combination of regular weight-bearing and muscle-strengthening exercise tailored to individual needs and ability. Its evidence review finds beneficial effects on BMD, while noting that clear evidence for fracture reduction from exercise alone is limited.

That distinction matters. Resistance and suitable impact exercise can provide a useful skeletal stimulus, but no routine guarantees a particular gain or removes the need for treatment in someone at high fracture risk. Swimming and cycling remain valuable for aerobic fitness and participation, even though they do not load the skeleton in the same way as walking, stair climbing, resistance work or appropriate impact activity.

Build gradually. If you have diagnosed osteoporosis, a vertebral fracture, unexplained severe pain, a high falls risk or a condition affecting movement, ask a physiotherapist or clinician to adapt the programme. Sudden jumping, heavy spinal loading and repeated loaded spinal flexion are not sensible starting points for everyone.

Match the method to the goal

Aim	Useful approach	Important limit
Load the hip and legs	Walking, stairs and suitable impact activity	Impact must match fracture risk, joints, balance and training history
Build force and function	Progressive resistance exercise for major muscle groups	Technique and progression matter more than chasing a heavy number
Reduce falls	Tailored balance, coordination, strength and functional practice	Generic balance drills do not replace assessment after recurrent or injurious falls
Support bone nutrition	Balanced meals containing calcium, protein and vitamin D sources	Supplements are not automatically needed and can interact with health conditions or medicines
Protect recovery	Adequate total energy, sleep and gradual training progression	Persistent fatigue, weight loss, menstrual disruption or recurrent bone stress injury needs clinical review

The protected guide to exercises for osteoporosis of the spine offers further movement context. Use it as education, not as a personalised prescription. A previous vertebral fracture, new pain, neurological symptoms or uncertainty about technique is a reason to obtain individual guidance.

The current NHS osteoporosis prevention page states that adults need 700 mg of calcium a day, preferably obtained from food, and 10 micrograms of vitamin D a day, equivalent to 400 IU. NOGG separately recommends prescribed vitamin D of at least 800 IU a day for postmenopausal women and men aged 50 or older with identified vitamin D insufficiency or risk factors for it. These are different contexts, not interchangeable universal supplement instructions.

Food sources of calcium can include dairy products, calcium-fortified alternatives, tofu, some leafy green vegetables and fish with soft edible bones. Protein can come from dairy foods, eggs, fish, meat, beans, lentils, nuts and seeds. People with kidney disease, malabsorption, pregnancy, frailty, an eating-disorder history or a medically restricted diet should seek individual dietary advice before using supplements or making major intake changes.

The source links to a Resting Metabolic Rate Test. RMR measures resting energy expenditure and can inform nutrition planning, but it does not measure bone density, diagnose low energy availability or determine a safe calorie deficit. It should not be used to justify aggressive restriction, particularly in someone already at risk of poor bone health.

Fall Prevention Hormone Health and Medication Options

Fracture prevention has two connected parts: improve skeletal resilience where possible and reduce the chance and impact of a fall. Loose rugs, poor lighting and unsuitable footwear can matter, but falls are not always simple household accidents. Dizziness, loss of consciousness, low blood pressure, impaired vision, reduced strength, neurological disease, alcohol and medicines can all contribute.

The current NICE falls guideline recommends assessment based on the circumstances and consequences of falls, not a simple prediction score. A comprehensive assessment can include cardiovascular examination, gait, balance and strength, vision, dizziness, cognition, long-term conditions, medication and osteoporosis risk. Interventions should then be tailored to the factors found.

Practical actions may include improving lighting, clearing walking routes, securing or removing loose rugs, checking footwear and arranging a home-hazard assessment. Falls-prevention exercise should be progressive and personalised, with balance, coordination, strength and power addressed by appropriately trained professionals. The Telomyx fall risk assessment article explains how these components fit together.

Ask for medical assessment after a fall involving injury, loss of consciousness, inability to get up or new neurological or cardiac symptoms. Recurrent falls, increasing unsteadiness or fear that is restricting normal activity also deserve review. Never stop a medicine suddenly because it may contribute to dizziness. A clinician or pharmacist can review the complete regimen and decide whether an adjustment is appropriate.

Hormone replacement therapy and bone-protective medicines can reduce fracture risk in selected people, but they are not generic wellness interventions. Current NOGG treatment guidance conditionally recommends considering HRT as a first-line option for some postmenopausal women aged 60 or younger who have high fracture risk and a low baseline risk of malignant and thromboembolic adverse events. The choice depends on symptoms, age, medical history, preferences and individual benefits and risks.

Other treatments include antiresorptive and anabolic medicines for defined clinical situations. Selection, duration, monitoring and safe stopping differ between drugs. Do not start, delay, stop or change osteoporosis treatment without the prescribing clinician, and do not use lifestyle measures to postpone assessment after a fragility fracture or when calculated risk is high.

Your Monitoring Plan and When to Seek Specialist Care

A useful plan answers three questions: what is being measured, when will it be reviewed, and what result would change management? Begin with fracture history and relevant clinical risks. Use FRAX when it applies, add central DEXA when it can refine a decision, and investigate secondary causes when osteoporosis or a fragility fracture is identified.

Repeat timing is individual. Follow-up BMD is most useful when there is a defined objective and the result is likely to influence care, such as monitoring treatment, reassessing after a new fracture or reviewing a new risk factor. A short interval may show measurement noise rather than biological change. Where possible, compare the same anatomical site on the same system under consistent quality-control procedures.

The source includes a protected catalogue link for Bundle - 2 x DEXA Scans. The availability of a multi-scan product does not set an appropriate interval or establish a medical indication. Each exposure needs a permitted purpose and fresh individual justification, and repeat scanning should not be scheduled simply for general wellness tracking.

Keep copies of reports and record the measured sites, scan dates, treatment, relevant health changes and fractures. Ask what the facility’s least significant change is before interpreting a small difference as improvement or decline. Bring new medicines, substantial weight change, menopause changes and new falls to the clinical review.

Seek prompt medical advice for a new low-trauma fracture, sudden severe back pain, rapid or marked height loss, new spinal deformity, progressive weakness, recurrent falls or symptoms suggesting an underlying illness. A previous hip or vertebral fracture, very high calculated risk, complex secondary cause or uncertainty about treatment may warrant specialist osteoporosis input.

For general information about the mobile clinic, see Telomyx. Mobile access does not change the distinction between a medically justified exposure and prohibited non-medical DEXA, and it does not replace a GP, fracture liaison service or specialist assessment when osteoporosis is suspected.

The main points are straightforward:

• Start with risk, not a scan purchased in isolation.
• Use resistance, weight-bearing and balance activity in a form that is safe for you.
• Meet nutrition needs without assuming that more supplements are better.
• Treat a T-score or Z-score as one part of the clinical picture.
• Review falls, medicines and health conditions as well as BMD.
• Act after a fragility fracture rather than waiting for another one.
