When Ought to You Get a DEXA Scan? Specialists Say Sooner Than You Assume

Bone loss begins to speed up for all ladies of their mid-30s, so in the event you’re beneath 50 and assume DEXA scans and bone density issues don’t apply to you—maintain up.

That is data you’ll need beneath your belt sooner reasonably than later. Let’s discuss 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, ladies’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 ladies 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, ladies 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Bone reworking—a wholesome, lifelong course of by which outdated or broken bone is damaged down and changed by new tissue—slows over time.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 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 components already qualify many ladies for early screening—and insurance coverage will usually cowl the scan with a physician’s prescription indicating only one.

How one can 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 possible lined for early testing.

Beneath is a non-exhaustive listing of danger classes that can assist you start a dialog along 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 ladies face the next danger of osteoporosis.

• Household Historical past – A guardian 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 top 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 identified with osteoporosis.

Hormonal & Reproductive Components

• Menopause-Associated Hormone Decline

• Early Menopause (pure or surgical)

• Amenorrhea / Irregular Menstrual Cycles

Dietary & Consuming Habits Components

Way of life Components

Illness-Associated Components

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

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

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

• Most cancers

• HIV/AIDS

• Anorexia Nervosa

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

Medicine-Associated Components

• Glucocorticoids / ACTH

• Antiepileptic Medicine

• Most cancers Hormonal Therapies

• Proton Pump Inhibitors (PPIs)

• SSRIs (Antidepressants)

• Thiazolidinediones (for Sort 2 Diabetes)

Along with this listing, on-line instruments such because the International Osteoporosis Foundation Risk Check, FRAX Fracture Risk Assessment Tool, and Garvan Fracture Risk Calculator may also help estimate your osteoporosis and fracture dangers.

Can I Get a DEXA Scan if I Don’t Have Any Danger Components?

Sure—you may 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, contemplate it an funding in prevention.

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

Be sure you name forward—not all imaging facilities provide self-pay DEXA scans and not using 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 identified utilizing the T-score. A decrease (extra adverse) rating signifies higher bone loss:

Word: Z-scores could also be extra helpful for figuring out secondary causes of bone loss in youthful ladies 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 components, most ladies are eligible—and smart—to get an early DEXA scan. Don’t assume your bones are wholesome simply since you really feel wholesome.

Discuss along 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 possibly can 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 usually achieved by early maturity, we additionally must encourage the subsequent era—our children and teenagers—to interact in bone-building actions now, in order that they’ll have a stronger basis for many years to return.

Hold lifting, leaping, and searching for sturdy bones at all ages. —Karin
