Risk Factors That May Warrant a Bone Density Scan
Bone health isn’t often top of mind—until there’s a problem. By the time fractures occur due to weakened bones, significant bone loss may have already taken place. This is why bone mineral density (BMD) scans are such a valuable preventive tool. They help detect early signs of bone thinning and osteoporosis before complications arise.
But how do you know if you should get a bone density scan? Let’s explore the key risk factors that may indicate it’s time to schedule one.
What Is a Bone Density Scan?
A bone mineral density scan, also called a DEXA scan, uses low-dose X-rays to measure the density of your bones—usually in the hips and spine. It’s a painless, non-invasive test that can help diagnose osteoporosis or assess your risk for fractures in the future.
Who Should Consider a Bone Density Scan?
While national guidelines often recommend bone density scans for women over 65 and men over 70, younger individuals may also need testing depending on their risk profile. You don’t have to wait until an injury or fracture prompts action.
Key Risk Factors That Warrant a BMD Scan
Here are the most common risk factors that may indicate you should consider getting a bone density scan:
1. Family History of Osteoporosis
If one or both of your parents had osteoporosis or suffered hip fractures, your own risk is higher due to genetic predisposition.
2. Previous Fractures After Minimal Trauma
Breaking a bone from a minor fall or bump may signal underlying bone weakness. A BMD scan can help uncover the cause.
3. Low Body Weight or Small Frame
People with a lean or petite body type often have less bone mass to begin with, putting them at greater risk for bone density loss over time.
4. Smoking and Alcohol Use
Smoking interferes with calcium absorption and reduces bone mass. Excessive alcohol use (more than two drinks a day) is also linked to weaker bones.
5. Lack of Physical Activity
Weight-bearing exercise strengthens bones. A sedentary lifestyle contributes to gradual bone loss, especially after age 40.
6. Vitamin D and Calcium Deficiency
Both nutrients are critical for bone strength. Long-term dietary deficiency increases the risk of weakened bones.
7. Use of Certain Medications
Long-term use of corticosteroids (e.g., prednisone), anticonvulsants, and some cancer treatments can accelerate bone loss.
8. Hormonal Changes
Women are at higher risk of osteoporosis post-menopause due to the sharp drop in estrogen. Men with low testosterone levels are also at risk.
9. Medical Conditions
Autoimmune diseases like rheumatoid arthritis, gastrointestinal disorders (like Crohn’s or celiac), thyroid disorders, and chronic kidney disease can all affect bone health.
10. Eating Disorders or History of Malnutrition
Anorexia, bulimia, or prolonged malnutrition can have long-term effects on bone density—even if the eating disorder was in the past.
Why Early Testing Matters
The earlier you detect bone loss, the more options you have to slow or even reverse it. Treatment may include lifestyle changes, supplements, or medication. In many cases, patients with osteopenia (mild bone loss) can prevent further deterioration with timely intervention.
Where to Get a Bone Density Scan
If you fall into any of the risk categories above—or simply want peace of mind—it’s worth booking a BMD scan with a trusted provider. We recommend scheduling your test through MBRI where you’ll receive expert imaging in a comfortable, professional setting. MBRI uses state-of-the-art DEXA technology and provides thorough, easy-to-understand reports to help you and your doctor make informed decisions.
