Why bone health matters — even before menopause
Bones are living, dynamic tissue: throughout life there’s a balance between bone formation and bone breakdown. Over time, after your mid-30s, bone breakdown can start to outpace bone formation.

This means that bone mass doesn’t stay static — without support (nutrition, activity, hormonal balance), bone density gradually declines. Because of this, by the time many women reach menopause, they may already have lost a portion of their “peak” bone mass.
Starting to think about bone health from your mid-30s gives you a chance to head off problems before they become serious.
What is a DEXA scan — and why it’s useful
A DEXA scan uses two low-dose X-rays to measure how dense (i.e. mineral-rich) your bones are.
The scan usually checks bones that are most at risk of fracture, like the hip and spine.
It is quick, painless, and involves very little radiation — much less than a standard X-ray.
The result gives a “score” (commonly a T-score or, in some cases, a Z-score), which shows whether your bone density is normal, lower than average (osteopenia), or low enough to be osteoporosis.
Importantly: bone loss often doesn’t cause symptoms until a fracture occurs. A DEXA scan therefore helps to uncover “silent” bone weakening before any broken bones.
Why women ~35+ — especially around menopause — should consider DEXA:
Bone loss speeds up around menopause
As women approach and go through menopause, their bodies produce less oestrogen. This hormonal change accelerates bone loss.
Research shows that significant loss of bone mineral density can occur during the “menopause transition.”
Up to 20% of bone loss may happen during the menopause transition or early post-menopause.
If you wait until bone loss is already advanced, prevention becomes harder. A DEXA scan around the late 30s–mid 40s can serve as a baseline — a reference point against which future bone changes are measured.
Early detection = opportunities for prevention
Detecting reduced bone density early (even if not yet “osteoporosis”) gives you and your clinician a chance to intervene. That might include:
Lifestyle changes — diet rich in calcium and vitamin D; regular weight-bearing or strength exercises; reducing smoking/alcohol; maintaining healthy weight.
Monitoring bone density over time, especially if there are additional risk factors (e.g. early menopause, low body weight, medications, chronic disease).
Considering medical treatments if indicated (especially if osteopenia or early bone loss is present).
By doing this before bone becomes fragile, you reduce the risk of fractures later — which can have serious implications, particularly for hip or spinal fractures.
The link between menopause, women’s bone health and bone density scanning
The menopause transition is a critical window: bone metabolism changes, bone loss accelerates, and the risk of osteoporosis climbs.
DEXA is a reliable, widely-accepted method to “see inside” bone density and track changes over time — as hormonal shifts, ageing, and lifestyle factors take effect.
With an early baseline scan (for example mid- to late-30s or 40s), you and your healthcare provider can customise a bone-health strategy — exercise, nutrition, monitoring — early. This helps preserve bone mass before significant loss, reducing fracture risk later in life.
In short: in the journey from perimenopause through menopause to older age, early and periodic bone-density assessment via DEXA gives women the best shot at maintaining bone strength, preventing fractures, and preserving mobility and quality of life.
What to discuss your bone health further?
If you’re a woman around 35+ (or heading toward menopause), you might ask:
“Would a DEXA scan be helpful for me now — given my family history / lifestyle / health?”
“If I start with a baseline scan, how often should I repeat it?” (Often this depends on your risk profile; if bone density is normal and no risk factors — frequent re-scans may not be needed.
“If the scan shows osteopenia or lowered density, what preventive steps should I take — lifestyle or medical?”
“How do hormonal changes (menopause, perimenopause, HRT, etc.) impact my bone health long-term — and how can I use that knowledge to protect my bones?”
