How often should bone health be checked after diagnosis?
In the UK, the frequency of bone health checks after a diagnosis of osteoporosis is tailored to your specific fracture risk, age, and the type of treatment you are receiving. While you might expect frequent scans, bone tissue changes relatively slowly, meaning that a repeat “check” usually involves a mix of long-term imaging and more regular clinical reviews. According to the NHS and NICE guidelines, the goal of monitoring is to ensure your medication is working effectively and to identify when it might be safe to consider a “treatment holiday.”
What We’ll Discuss in This Article
- Typical timelines for repeat DEXA scans
- The role of regular blood and kidney function tests
- Annual clinical reviews and FRAX reassessments
- Monitoring requirements for specific medications (e.g., Denosumab)
- Why “height checks” are a simple but vital part of monitoring
- When to request an unscheduled review with your GP
Repeat DEXA Scans: The 3-to-5-year milestone.
A DEXA (Dual-energy X-ray Absorptiometry) scan is the gold standard for measuring bone mineral density, but because bone remodelling takes time, having a scan every year is rarely useful.
- Standard Monitoring: For most people on oral bisphosphonates (like Alendronic acid), a repeat DEXA scan is usually recommended every 3 to 5 years.
- High-Risk or Rapid Loss: If you have severe osteoporosis, are on high-dose steroids, or are taking a “bone-building” medication like Teriparatide, your specialist may request a scan sooner, typically after 2 years.
- Stable Density: If your bone density is stable and you have not had new fractures, your GP may decide that further scans are only needed if your clinical situation changes.
Regular blood tests and safety monitoring.
While the “bone density” is checked every few years, the “safety” of your treatment is often checked much more frequently through blood tests.
- Bone Profile: This checks your calcium, phosphate, and vitamin D levels. In the UK, it is common to have these checked annually, or before starting a new treatment.
- Kidney Function (eGFR): Because many bone drugs are cleared by the kidneys, your GP will monitor your kidney function at least once a year.
- Denosumab (Prolia) Monitoring: If you receive 6-monthly injections, you will typically need a blood test to check your calcium levels before every dose to ensure it is safe to proceed.
The Annual Clinical Review.
Most GP surgeries in the UK perform an annual medication review. For osteoporosis, this check-up should ideally include:
- A Review of Side Effects: Ensuring you are tolerating your tablets or injections well.
- Adherence Check: Confirming you are taking the medication correctly (e.g., on an empty stomach with a full glass of water).
- FRAX Reassessment: Your doctor may re-calculate your 10-year fracture risk score to see if it has improved.
- Height Measurement: A loss of height can be a “silent” sign of a new spinal fracture. Many UK clinics aim to check your height every year.
Monitoring the “Treatment Holiday.”
In the UK, after 5 years of oral tablets (or 3 years of intravenous infusions), your GP will conduct a major review. If your bone density has improved and you haven’t had recent fractures, you might be advised to take a “treatment holiday.”
During this pause, your bone health is still monitored, usually with a repeat DEXA scan and a FRAX assessment every 2 to 3 years to decide when the medication should be restarted.
Conclusion
Bone health monitoring in the UK is a marathon, not a sprint. While formal DEXA scans usually occur every 3 to 5 years, annual reviews with your GP and regular blood tests for calcium and kidney function are essential for staying safe. By attending these regular checks, you ensure that your treatment remains “optimal” for your changing needs. If you have any concerns about your treatment or experience a new fracture, you should seek a medical review immediately. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Can I get a DEXA scan on the NHS every year if I pay for it?
No, even in private practice, annual scans are rarely recommended because the “margin of error” in the machine is often larger than the small amount of bone change that happens in 12 months.
Why does my GP check my height at my review?
A height loss of more than 4cm (about 1.5 inches) is a strong clinical indicator that you may have suffered a “silent” vertebral compression fracture.
Will my bone health be checked more often if I am on steroids?
Yes, because steroids can cause rapid bone loss, the Royal Osteoporosis Society suggests more frequent monitoring, sometimes with a repeat scan after just 12 to 24 months.
Do I need a blood test before every Alendronic acid tablet?
No; for oral tablets, an annual blood test is usually sufficient unless you have other health conditions like kidney disease.
What is a “bone turnover marker” test?
This is a specialised blood or urine test that measures how quickly your bone is being broken down. While used in some specialist UK hospitals, it is not yet a routine part of GP monitoring.
How do I know if my medication is working?
If your DEXA scan shows that your bone density is “stable” or “increasing,” and you haven’t suffered any new fractures, the treatment is considered a success.
Should I ask for a review if I have dental surgery planned?
Yes, it is important to discuss any planned extractions or implants with your GP, as they may want to review the timing of your medication.
