Bone density scans, often called DEXA scans, are simple tests that measure how strong and dense your bones are. They help doctors figure out if you have osteoporosis or if you’re at risk of breaking a bone easily. The scan is quick and painless — you lie down while a machine uses low-dose X-rays to check your hips and spine, usually taking about 10 to 20 minutes.
**When Should You Get a Bone Density Scan?**
Doctors recommend bone density tests mainly for people who might have weak bones or are at risk of osteoporosis. This includes:
– Postmenopausal women
– Older adults
– People who take steroids for a long time
– Those with certain medical conditions like hyperparathyroidism
– Anyone who has had fractures from minor injuries
If you fall into these groups, your doctor may suggest getting tested to see how healthy your bones are.
**How Often Should You Have the Scan?**
The frequency depends on your individual risk:
– If you have normal bone density or only mild thinning (osteopenia), testing every two years is usually enough.
– For those diagnosed with osteoporosis or moderate bone loss, scans might be done every one to two years to keep track of changes.
– If you’re starting or changing medications for osteoporosis, doctors may want to do the scan sooner—sometimes as early as six months after starting treatment—to see how well the medicine is working.
Insurance programs like Medicare generally cover one scan every 24 months unless there’s a special reason for an earlier test, such as new fractures or medication changes.
**Preparing for Your Bone Density Scan**
To get accurate results:
– Avoid taking calcium supplements for at least 24 hours before the test because they can affect measurements.
– Wear comfortable clothes without metal parts like zippers or buttons since metal can interfere with the scan; sometimes you’ll need to change into a gown.
– Don’t schedule this test within 24 hours of other imaging tests that use contrast dye because it might affect accuracy.
Bone density scans provide valuable information about your bone health so that steps can be taken early if needed—whether that’s lifestyle changes, supplements, or medications—to reduce fracture risk and maintain strong bones over time.
