DEXA scanning remains the gold standard for bone density measurement. This non-invasive test uses low-dose X-rays to measure bone mineral density at the hip and lumbar spine. The procedure takes approximately 10-30 minutes and provides precise measurements that form the basis for diagnosis. DEXA results are reported as T-scores, comparing your bone density to that of a healthy 30-year-old adult, and Z-scores, comparing you to others of your age and gender.

If you’re concerned about bone health or have risk factors for osteoporosis, early screening and proper management can make a significant difference in maintaining your quality of life and preventing fractures. Osteoporosis, often called the “silent disease,” affects millions worldwide and can progress without obvious symptoms until a fracture occurs. In Singapore, where our population is rapidly ageing, osteoporosis screening and management has become essential for maintaining long-term health and independence. Our comprehensive approach combines accurate bone density assessment with personalised treatment strategies to help protect your bones and reduce fracture risk.
What is Osteoporosis Screening & Management?
Osteoporosis screening and management encompasses a systematic approach to detecting, monitoring, and treating decreased bone density and strength. This process begins with specialised diagnostic tests, primarily dual-energy X-ray absorptiometry (DEXA) scans, which measure bone mineral density at key sites like the hip and spine. These measurements help determine whether you have normal bone density, osteopenia (low bone mass), or osteoporosis.
The screening process goes beyond simple bone density measurement. It includes comprehensive risk assessment using validated tools like FRAX (Fracture Risk Assessment Tool), which calculates your 10-year probability of experiencing a major osteoporotic fracture. This assessment considers multiple factors including age, gender, previous fractures, family history, and lifestyle factors.
Management of osteoporosis involves a multifaceted approach tailored to your specific needs and risk profile. This may include lifestyle modifications, nutritional optimisation, exercise programmes, and when necessary, medications to slow bone loss or promote bone formation. Regular monitoring ensures that treatment remains effective and allows for timely adjustments based on your response and changing needs.
Who is a Suitable Candidate?
Ideal Candidates
- Women aged 65 and above, regardless of risk factors
- Men aged 70 and above
- Postmenopausal women under 65 with risk factors
- Men aged 50-69 with clinical risk factors
- Individuals with a history of fragility fractures
- People taking medications known to affect bone density (corticosteroids, certain anti-seizure medications)
- Those with medical conditions affecting bone health (rheumatoid arthritis, hyperthyroidism, coeliac disease)
- Adults with height loss of more than 4cm
- Individuals with a family history of osteoporosis or hip fractures
- People with low body weight (BMI less than 19)
Contraindications
- Pregnancy (for DEXA scanning due to radiation exposure)
- Recent contrast studies that may interfere with bone density measurements
- Severe spinal deformities that prevent proper positioning for scanning
- Metal implants in measurement areas that affect scan accuracy

The decision to undergo osteoporosis screening should be made in consultation with your healthcare provider, who can evaluate your individual risk factors and determine the appropriate timing and frequency of screening based on your personal health profile.
Screening Methods & Diagnostic Approaches
Dual-Energy X-ray Absorptiometry (DEXA)
Vertebral Fracture Assessment (VFA)
VFA uses the same DEXA machine to detect vertebral compression fractures, which often occur without symptoms but indicate significant osteoporosis. This lateral spine MRI can identify fractures that might otherwise go unnoticed, providing crucial information for treatment planning and fracture risk assessment.
Laboratory Testing
Blood and urine tests help identify underlying causes of bone loss and guide treatment selection. These may include calcium and vitamin D levels, thyroid function tests, parathyroid hormone levels, and bone turnover markers. These markers can help monitor treatment response and identify secondary causes of osteoporosis.
Quantitative MRI
While not as precise as DEXA, heel MRI provides a radiation-free screening option that can identify individuals who may benefit from further evaluation. This portable technology measures bone quality at peripheral sites and serves as a useful initial screening tool in community settings.

The Screening & Management Process
Pre-Screening Preparation
Before your screening appointment, you’ll complete a comprehensive health questionnaire covering medical history, medications, fracture history, and lifestyle factors. No special preparation is required for DEXA scanning, though you should avoid calcium supplements for 24 hours before the test. Wear comfortable clothing without metal fasteners, and inform your provider if you’ve recently had contrast studies or nuclear medicine scans. Your healthcare provider will review your risk factors and determine which screening tests are appropriate.
During the Screening
The DEXA scan is painless and non-invasive. You’ll lie on a padded table while the scanner arm passes over your body, focusing on the hip and spine. The technologist ensures proper positioning for accurate measurements. The radiation exposure is minimal, less than a standard chest X-ray. Additional sites may be scanned if primary sites are unsuitable due to arthritis or previous surgery. The entire process typically takes 10-30 minutes, depending on the sites being measured.
Immediate Post-Screening
Results are usually available within a few days. Your healthcare provider will interpret the findings in context with your overall health profile and risk factors. Based on the results, you’ll receive a comprehensive assessment that includes your bone density measurements, fracture risk calculation, and treatment recommendations if indicated. This consultation provides an opportunity to discuss the findings, understand their implications, and develop a personalised management plan.
Treatment & Management Strategies
Lifestyle Modifications
The foundation of osteoporosis management involves comprehensive lifestyle changes. Weight-bearing exercises like walking, dancing, and resistance training help stimulate bone formation and maintain density. Balance and posture exercises reduce fall risk, a crucial factor in fracture prevention. Smoking cessation and limiting alcohol intake are essential, as both habits accelerate bone loss.
Nutritional Optimisation
Adequate calcium and vitamin D intake forms the cornerstone of bone health. Adults typically need 1,000-1,200mg of calcium daily, preferably from dietary sources like dairy products, leafy greens, and fortified foods. Vitamin D requirements range from 800-1,000 IU daily, often requiring supplementation in Singapore despite our sunny climate, as many people have limited sun exposure. Protein intake plays a vital role in maintaining bone and muscle mass.
Pharmacological Interventions
When lifestyle modifications alone are insufficient, medications may be prescribed based on your fracture risk and individual factors. Bisphosphonates, commonly prescribed medications, work by slowing bone breakdown. These can be taken orally weekly or monthly, or given intravenously annually. Hormone therapy may be considered for postmenopausal women with additional menopausal symptoms. Newer treatments include monoclonal antibodies that either reduce bone breakdown or promote bone formation, offering alternatives for those who cannot tolerate or don’t respond to traditional treatments.
Monitoring and Follow-up
Regular monitoring ensures treatment effectiveness and allows for timely adjustments. DEXA scans are typically repeated every 1-2 years to track bone density changes. Bone turnover markers may be checked more frequently to assess early treatment response. Annual height measurements and spine MRI help detect new vertebral fractures. Your management plan will be adjusted based on your response to treatment, changes in risk factors, and any new medical conditions.

Benefits of Osteoporosis Screening & Management
Early detection through screening enables intervention before significant bone loss occurs, potentially preventing the progression from osteopenia to osteoporosis. This proactive approach substantially reduces fracture risk, particularly hip and vertebral fractures that can severely impact quality of life and independence. Proper management helps maintain mobility and physical function, allowing you to continue enjoying daily activities and exercise.
Comprehensive osteoporosis care addresses associated health concerns. The focus on nutrition and exercise benefits overall health, improving muscle strength, balance, and cardiovascular fitness. Fall prevention strategies incorporated into management plans reduce injury risk beyond fractures. Many patients report increased confidence in their physical abilities and reduced anxiety about bone health after beginning treatment.
The economic benefits are significant. Preventing fractures avoids substantial medical costs, lost work time, and potential long-term care needs. Early intervention is more cost-effective than treating fractures and their complications. Maintaining bone health preserves independence, reducing the burden on family caregivers and healthcare systems.
Risks & Potential Complications
Common Side Effects
DEXA scanning involves minimal radiation exposure, though the dose is very low and generally considered safe for routine screening. Some medications may cause mild gastrointestinal symptoms like heartburn or nausea, particularly oral bisphosphonates. These effects can often be managed by taking medications correctly and adjusting the dosing schedule. Calcium supplements may cause constipation or bloating in some individuals, which can be addressed by dividing doses or choosing different formulations.
Rare Complications
Uncommon but serious medication side effects require awareness and monitoring. Bisphosphonates rarely cause osteonecrosis of the jaw, primarily in patients undergoing dental procedures. Atypical femur fractures, though extremely rare, may occur with long-term bisphosphonate use. Some individuals may experience hypocalcaemia if vitamin D deficiency isn’t corrected before starting certain treatments. Injectable medications may cause injection site reactions or, rarely, allergic responses.
Our specialists carefully evaluate your risk profile and medical history to select the safe and appropriate treatments. Regular monitoring and follow-up help identify any concerns early, allowing for prompt management or treatment adjustment. The benefits of preventing osteoporotic fractures typically outweigh these potential risks for most patients.
Cost Considerations
The cost of osteoporosis screening and management varies depending on the extent of testing required and treatment approaches selected. Initial screening typically includes DEXA scanning and consultation fees. Additional laboratory tests may be recommended based on your risk profile and initial findings. The comprehensive nature of the assessment ensures accurate diagnosis and appropriate treatment planning.
Ongoing management costs depend on your treatment plan. Lifestyle interventions like dietary counselling and exercise programmes represent valuable investments in long-term health. Medication costs vary widely depending on the type prescribed and whether generic options are available. Regular monitoring through follow-up DEXA scans and consultations ensures treatment effectiveness.
Many patients find that investing in preventive bone health management is cost-effective compared to the potential expenses of treating fractures and their complications. Our team can discuss various treatment options and their associated costs during your consultation, helping you make informed decisions about your bone health management.
Frequently Asked Questions
How often should I undergo osteoporosis screening?
Screening frequency depends on your initial results and risk factors. If your bone density is normal and you have no major risk factors, rescreening may be recommended in 5-10 years. Those with osteopenia typically need screening every 2-5 years, while patients on treatment for osteoporosis usually have DEXA scans every 1-2 years. Your specialist will determine the appropriate interval based on your individual circumstances and response to any treatments.
Can osteoporosis be reversed, or only slowed down?
While osteoporosis cannot be completely “cured,” significant improvements in bone density are possible with appropriate treatment. Some newer medications can increase bone formation, leading to meaningful gains in bone density. Most treatments focus on preventing further bone loss and reducing fracture risk. Early intervention at the osteopenia stage can prevent progression to osteoporosis. The goal is to maintain or improve bone strength to reduce fracture risk and preserve quality of life.
Is DEXA scanning safe, and how does it compare to regular X-rays?
DEXA scanning is very safe, using extremely low radiation doses – approximately one-tenth the radiation of a standard chest X-ray. The radiation exposure is comparable to the natural background radiation you’d receive during a transcontinental flight. The test is painless, non-invasive, and requires no injections or special preparation. For most people, the benefits of accurate bone density assessment outweigh the minimal radiation exposure.
What’s the difference between osteopenia and osteoporosis?
Both conditions involve reduced bone density, but differ in severity. Osteopenia indicates bone density that’s lower than normal but not low enough to be classified as osteoporosis. Think of it as a warning stage. Osteoporosis represents more significant bone loss with substantially increased fracture risk. On DEXA scans, osteopenia is defined as a T-score between -1.0 and -2.5, while osteoporosis is diagnosed when the T-score is -2.5 or lower. Treatment approaches differ based on this classification and your overall fracture risk.
Can younger people develop osteoporosis?
Yes, though less common, younger adults can develop osteoporosis due to various factors. Secondary osteoporosis may result from medical conditions like eating disorders, coeliac disease, or hormonal imbalances. Long-term use of certain medications, particularly corticosteroids, can cause bone loss at any age. Genetic factors, inadequate nutrition during growth years, and excessive exercise leading to amenorrhoea in young women are other causes. Early detection and treatment are particularly important in younger patients to prevent long-term complications.
How long do I need to continue osteoporosis treatment?
Treatment duration varies based on individual factors and response to therapy. Most medications require several years of use to achieve optimal benefit. Bisphosphonates are often prescribed for 3-5 years initially, followed by a reassessment to determine if a “drug holiday” is appropriate. Some patients may need indefinite treatment, especially those at high fracture risk. Lifestyle modifications including adequate calcium, vitamin D, and exercise should continue lifelong. Your specialist will regularly evaluate your need for continued pharmacological treatment based on bone density changes and fracture risk assessment.
Can exercise help if I already have osteoporosis?
Exercise remains beneficial even after osteoporosis diagnosis, though the approach needs modification for safety. Weight-bearing exercises like walking and gentle strength training help maintain bone density and muscle strength. Balance and posture exercises are particularly important for fall prevention. High-impact activities and exercises involving spinal flexion should be avoided to reduce fracture risk. A physiotherapist experienced in osteoporosis can design a safe, effective exercise programme tailored to your condition and fitness level.
