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.
