Why Bone Density Scan (DEXA) Is Needed
A DEXA scan is recommended to diagnose osteoporosis or osteopenia, particularly in postmenopausal women, older adults, and people on long-term steroid therapy. It's also used to assess fracture risk in patients with a family history of osteoporosis, low body weight, or conditions like rheumatoid arthritis and hyperthyroidism that affect bone metabolism. Doctors also order it to monitor how well osteoporosis treatment is working over time.
Signs You May Need Bone Density Scan (DEXA)
Osteoporosis often has no symptoms until a fracture occurs, so a DEXA scan is frequently recommended based on risk factors like age and menopause rather than specific symptoms. However, unexplained back pain, loss of height over time, a stooped posture, or a fracture from a minor fall are warning signs that prompt bone density testing.
Types of Bone Density Scan (DEXA)
The gold-standard central DEXA scan measures density at the hip and spine, the sites most predictive of fracture risk. Peripheral DEXA machines can also screen smaller bones like the wrist or heel, often used for quick screening before a central scan is ordered. Results are reported as T-scores and Z-scores that compare your bone density to healthy reference populations.

Frequently Asked Questions
Is a DEXA scan safe?
Yes, it uses a very low dose of radiation, far less than a standard X-ray, making it safe for routine and repeated screening.
How should I prepare for a DEXA scan?
You should avoid calcium supplements for 24 hours before the test and wear loose clothing without metal zippers or buttons.
How often should I get a bone density scan?
This depends on your age and risk factors, but many doctors recommend every 1-2 years for those at higher risk — ask your physician what's right for you.
What does a low T-score mean?
A T-score below -2.5 typically indicates osteoporosis, while a score between -1 and -2.5 suggests osteopenia; your doctor will interpret this alongside your overall fracture risk.
Can osteoporosis be reversed?
While bone loss can't always be fully reversed, medications, calcium, vitamin D, and weight-bearing exercise can significantly slow progression and reduce fracture risk — consult a specialist for a personalized plan.
