When Ought to You Get a DEXA Scan? Consultants Say Sooner Than You Suppose

Bone loss begins to speed up for all girls of their mid-30s, so in case you’re underneath 50 and suppose DEXA scans and bone density issues don’t apply to you—maintain up.

That is data you’ll need underneath your belt sooner somewhat than later. Let’s discuss why.

What’s a DEXA Scan?

A DEXA scan (quick 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 modifications 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 Suppose

At this yr’s BHOF Interdisciplinary Symposium on Osteoporosis, girls’s well being researcher Dr. Amanda Clark stated plainly: “Ready till age 65 to judge skeletal well being is simply too late.”

Why? As a result of girls start to lose bone quickly within the yr earlier than their last menstrual interval (the official marker of menopause), and that elevated charge of loss continues for about two years after. On this quick window, girls lose a median of 10% of their whole bone mass.

Because the common age of menopause is between 45 and 55, a girl may very well be dropping bone for 10 to twenty years with none consciousness or intervention.

Bone transforming—a wholesome, lifelong course of wherein outdated or broken bone is damaged down and changed by new tissue—slows over time.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 through the menopausal transition, when estrogen—a key driver of bone formation—declines.

Whereas the CDC and the Bone Well being & Osteoporosis Basis (BHOF) nonetheless advocate a primary DEXA scan at age 65, many specialists are calling for up to date tips that replicate rising proof: Girls profit from having a baseline scan a lot earlier. Quite a few danger elements already qualify many ladies for early screening—and insurance coverage will usually cowl the scan with a physician’s prescription indicating only one.

Methods to Get a Baseline DEXA Sooner

Insurance coverage usually covers a DEXA scan when osteoporosis danger is medically justified. With so many danger elements—starting from physique composition to drugs—most ladies are doubtless lined for early testing.

Under is a non-exhaustive record of danger classes that will help you start a dialog together with your healthcare supplier:

Physique Composition & Demographic Threat Elements

• Low Physique Weight / Slender Construct – Much less bone mass will increase vulnerability to loss.

• Race – White and Asian girls face the next danger of osteoporosis.

• Household Historical past – A mum or dad with osteoporosis or a fragility fracture raises your danger.*

• Fall Historical past – A bent to fall will increase fracture danger.*

Even minor falls (from standing peak or much less) that lead to fractures needs to 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 Elements

• Menopause-Associated Hormone Decline

• Early Menopause (pure or surgical)

• Amenorrhea / Irregular Menstrual Cycles

Dietary & Consuming Conduct Elements

Way of life Elements

Illness-Associated Elements

• Endocrine & Hormonal Problems (e.g., hyperthyroidism, Cushing’s)

• Gastrointestinal Illnesses (e.g., celiac, Crohn’s)

• Autoimmune Situations (e.g., rheumatoid arthritis)

• Most cancers

• HIV/AIDS

• Anorexia Nervosa

• Vertebral Abnormalities (e.g., scoliosis, unexplained peak loss)

Remedy-Associated Elements

• Glucocorticoids / ACTH

• Antiepileptic Medication

• Most cancers Hormonal Therapies

• Proton Pump Inhibitors (PPIs)

• SSRIs (Antidepressants)

• Thiazolidinediones (for Sort 2 Diabetes)

Along with this record, on-line instruments such because the Worldwide Osteoporosis Basis Threat Verify, FRAX Fracture Threat Evaluation Device, and Garvan Fracture Threat Calculator might help estimate your osteoporosis and fracture dangers.

Can I Get a DEXA Scan if I Don’t Have Any Threat Elements?

Sure—you possibly can nonetheless select to get one. Out-of-pocket prices usually vary from $100–$250, and you’ll typically use HSA/FSA funds. Whereas it’s an upfront expense, think about it an funding in prevention.

A baseline scan provides you data. And data provides you energy.

Make sure to 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 common of individuals your age and intercourse.

Osteoporosis is recognized utilizing the T-score. A decrease (extra destructive) rating signifies larger 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 proportion 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 big selection of danger elements, most ladies are eligible—and sensible—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 going on whether or not you see it or not.

The excellent news? You’ll be able to gradual it down and even construct bone by partaking in confirmed, proactive methods like progressive power coaching and influence coaching. And since peak bone mass is usually achieved by early maturity, we additionally have to encourage the subsequent technology—our youngsters and youths—to have interaction in bone-building actions now, in order that they’ll have a stronger basis for many years to come back.

Maintain lifting, leaping, and looking for sturdy bones at all ages. —Karin
