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 if you happen to’re underneath 50 and assume DEXA scans and bone density considerations don’t apply to you—maintain up.

That is data you’ll need underneath your belt sooner quite 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 check 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 Would possibly Want a DEXA Scan Sooner Than You Suppose

At this 12 months’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 12 months earlier than their remaining 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 mean of 10% of their complete bone mass.

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

Bone transforming—a wholesome, lifelong course of during which outdated or broken bone is damaged down and changed by new tissue—slows over time.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 elements already qualify many ladies for early screening—and insurance coverage will sometimes cowl the scan with a health care provider’s prescription indicating only one.

How one can Get a Baseline DEXA Sooner

Insurance coverage sometimes covers a DEXA scan when osteoporosis danger is medically justified. With so many danger elements—starting from physique composition to medicines—most girls are possible coated for early testing.

Beneath is a non-exhaustive record of danger classes that can assist you start a dialog together with your healthcare supplier:

Physique Composition & Demographic Threat 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 top or much less) that end in fractures needs to be thought-about pink 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 Conduct Components

Way of life Components

Illness-Associated Components

• Endocrine & Hormonal Problems (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 record, on-line instruments such because the International Osteoporosis Foundation Risk Check, FRAX Fracture Risk Assessment Tool, and Garvan Fracture Risk Calculator will help estimate your osteoporosis and fracture dangers.

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

Sure—you possibly can nonetheless select to get one. Out-of-pocket prices sometimes vary from $100–$250, and you’ll usually 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.

Remember to name forward—not all imaging facilities provide self-pay DEXA scans with no referral.

What Do My DEXA Outcomes Imply?

DEXA scan outcomes are sometimes 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 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 wide selection of danger elements, most girls are eligible—and clever—to get an early DEXA scan. Don’t assume your bones are wholesome simply since you really feel wholesome.

Discuss 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 sluggish 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 have to encourage the following era—our youngsters and teenagers—to interact in bone-building actions now, so that they’ll have a stronger basis for many years to come back.

Preserve lifting, leaping, and searching for robust bones at all ages. —Karin
