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

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

That is info 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 12 months’s BHOF Interdisciplinary Symposium on Osteoporosis, girls’s well being researcher Dr. Amanda Clark mentioned plainly: “Ready till age 65 to judge 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 ultimate menstrual interval (the official marker of menopause), and that elevated charge of loss continues for about two years after. On this brief window, girls lose a mean of 10% of their complete bone mass.

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

Bone transforming—a wholesome, lifelong course of during which previous 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 in the course of 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 tips 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 usually cowl the scan with a health care provider’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 elements—starting from physique composition to medicines—most girls are seemingly coated for early testing.

Under 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 mother or father 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 ought to be thought of pink flags. For instance, in case your mother broke her wrist tripping over a rug, that’s thought of 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 Ailments (e.g., celiac, Crohn’s)

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

• Most cancers

• HIV/AIDS

• Anorexia Nervosa

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

Medicine-Associated Components

• Glucocorticoids / ACTH

• Antiepileptic Medication

• Most cancers Hormonal Therapies

• Proton Pump Inhibitors (PPIs)

• SSRIs (Antidepressants)

• Thiazolidinediones (for Kind 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’ll be able to nonetheless select to get one. Out-of-pocket prices usually 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 offers you data. And data offers you energy.

Make sure to 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 of 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 damaging) rating signifies higher bone loss:

Notice: 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 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 possibly can sluggish it down and even construct bone by participating 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 following era—our children and youths—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 robust bones at all ages. —Karin
