Bone loss begins to speed up for all girls of their mid-30s, so should you’re below 50 and suppose DEXA scans and bone density issues don’t apply to you—maintain up.
That is data you’ll need below your belt sooner reasonably than later. Let’s speak about why.
What’s a DEXA Scan?
A DEXA scan (brief for dual-energy x-ray absorptiometry) is a fast, non-invasive take a look at that measures the mineral content material of your bones to evaluate bone density and monitor adjustments over time.
Whereas it makes use of a small quantity of radiation, publicity is minimal—about one-tenth that of a chest x-ray and fewer than what you’d get from a single day of background radiation.
The scan takes about 10 minutes. You’ll lie on a desk whereas an imaging arm passes over key websites—mostly the lumbar backbone, hip, femoral neck, and wrist.
Why You May Want a DEXA Scan Sooner Than You Assume
At this yr’s BHOF Interdisciplinary Symposium on Osteoporosis, girls’s well being researcher Dr. Amanda Clark stated plainly: “Ready till age 65 to guage skeletal well being is just too late.”
Why? As a result of girls start to lose bone quickly within the yr earlier than their closing menstrual interval (the official marker of menopause), and that elevated fee of loss continues for about two years after. On this brief window, girls lose a median of 10% of their complete bone mass.
For the reason that common age of menopause is between 45 and 55, a lady might be shedding bone for 10 to twenty years with none consciousness or intervention.
Bone transforming—a wholesome, lifelong course of through which outdated or broken bone is damaged down and changed by new tissue—slows over time. By our mid-30s, bone resorption begins to outpace bone formation, leading to a gradual however regular decline in bone mass.
This loss accelerates throughout the menopausal transition, when estrogen—a key driver of bone formation—declines.
Whereas the CDC and the Bone Well being & Osteoporosis Basis (BHOF) nonetheless suggest a primary DEXA scan at age 65, many consultants are calling for up to date pointers that mirror rising proof: Girls profit from having a baseline scan a lot earlier. Quite a few danger components already qualify many ladies for early screening—and insurance coverage will usually cowl the scan with a physician’s prescription indicating only one.
Learn how to Get a Baseline DEXA Sooner
Insurance coverage usually covers a DEXA scan when osteoporosis danger is medically justified. With so many danger components—starting from physique composition to drugs—most ladies are doubtless coated for early testing.
Under is a non-exhaustive checklist of danger classes that can assist you start a dialog together with your healthcare supplier:
Physique Composition & Demographic Danger Components
-
Low Physique Weight / Slender Construct – Much less bone mass will increase vulnerability to loss.
-
Race – White and Asian girls face a better danger of osteoporosis.
-
Household Historical past – A mum or dad with osteoporosis or a fragility fracture raises your danger.*
-
Fall Historical past – An inclination to fall will increase fracture danger.*
Even minor falls (from standing peak or much less) that end in fractures must be thought-about crimson flags. For instance, in case your mother broke her wrist tripping over a rug, that’s thought-about a fragility fracture—even when she wasn’t formally recognized with osteoporosis.
Hormonal & Reproductive Components
-
Menopause-Associated Hormone Decline
-
Early Menopause (pure or surgical)
-
Amenorrhea / Irregular Menstrual Cycles
Dietary & Consuming Conduct Components
Life-style Components
Illness-Associated Components
-
Endocrine & Hormonal Problems (e.g., hyperthyroidism, Cushing’s)
-
Gastrointestinal Ailments (e.g., celiac, Crohn’s)
-
Autoimmune Circumstances (e.g., rheumatoid arthritis)
-
Most cancers

Vertebral Abnormalities (e.g., scoliosis, unexplained peak loss)
Treatment-Associated Components
-
Glucocorticoids / ACTH
-
Antiepileptic Medicine
-
Most cancers Hormonal Therapies
-
Proton Pump Inhibitors (PPIs)
-
SSRIs (Antidepressants)
-
Thiazolidinediones (for Kind 2 Diabetes)
Along with this checklist, on-line instruments such because the International Osteoporosis Foundation Risk Check, FRAX Fracture Risk Assessment Tool, and Garvan Fracture Risk Calculator can assist estimate your osteoporosis and fracture dangers.
Can I Get a DEXA Scan if I Don’t Have Any Danger Components?
Sure—you’ll be able to nonetheless select to get one. Out-of-pocket prices usually vary from $100–$250, and you may typically use HSA/FSA funds. Whereas it’s an upfront expense, think about it an funding in prevention.
A baseline scan offers you information. And information offers you energy.
Be sure you name forward—not all imaging facilities provide self-pay DEXA scans with out a referral.
What Do My DEXA Outcomes Imply?
DEXA scan outcomes are usually reported as T-scores and Z-scores.
- The T-score compares your bone mineral density (BMD) to that of a wholesome 30-year-old grownup of the identical organic intercourse (thought-about peak bone mass).
- The Z-score compares your BMD to the typical of individuals your age and intercourse.
Osteoporosis is recognized utilizing the T-score. A decrease (extra destructive) rating signifies higher bone loss:
Word: Z-scores could also be extra helpful for figuring out secondary causes of bone loss in youthful girls and premenopausal populations.
- A T-score between -1.0 and -2.5 signifies low bone mass (osteopenia).
- A T-score of -2.5 or decrease signifies osteoporosis.
Every T-score level roughly correlates with a share of bone loss. For instance:
- A T-score of -1.0 displays about 10% bone loss
- A T-score of -2.5 displays roughly 25% bone loss
The Backside Line
Given the wide selection of danger components, most ladies are eligible—and clever—to get an early DEXA scan. Don’t assume your bones are wholesome simply since you really feel wholesome.
Speak together with your physician about your private danger profile and ask for a prescription to get a baseline scan. Out of your mid-30s on, bone loss is occurring whether or not you see it or not.
The excellent news? You may gradual it down and even construct bone by partaking in confirmed, proactive methods like progressive strength training and impact training. And since peak bone mass is generally achieved by early maturity, we additionally have to encourage the subsequent technology—our youngsters and teenagers—to interact in bone-building actions now, in order that they’ll have a stronger basis for many years to return.
Maintain lifting, leaping, and searching for sturdy bones at all ages. —Karin
