One in two women and one in four men over age 50 will break a bone because of osteoporosis. Yet many people don’t know they have the disease until after a fracture happens.
Osteoporosis weakens bones over time, often without causing symptoms. A bone density scan can detect bone loss early, giving you and your healthcare provider the opportunity to take steps to protect your bone health before a serious injury occurs.
What is a bone density scan?
A bone density scan, also called a DEXA scan, is a low-dose X-ray that measures the strength of your bones. During the exam, you’ll lie on a table while a scanner measures the density of your hip and spine. The test usually takes less than 20 minutes.
The results help your provider determine whether your bones are healthy, show early bone loss or have osteoporosis.
Who should get screened?
The U.S. Preventive Services Task Force (USPSTF) recommends bone density screening for:
- Women age 65 and older
- Postmenopausal women younger than 65 who have an increased risk of osteoporosis
Your provider may also recommend a scan if you have other risk factors, including:
- A broken bone after age 50
- A family history of osteoporosis or hip fractures
- Long-term use of steroid medications
- Low body weight
- Smoking or heavy alcohol use
- Certain medical conditions that affect bone health
Although osteoporosis is more common in women, men can develop it too. Your provider can help determine whether screening is appropriate based on your age, health history and risk factors.
Why early detection matters
Osteoporosis is often called a “silent disease” because bone loss happens gradually and without symptoms. A bone density scan can identify changes before a fracture occurs, making it easier to start treatment early.
Depending on your results, your provider may recommend:
- Weight-bearing and strength-training exercise
- Calcium and vitamin D supplementation
- Lifestyle changes, such as quitting smoking
- Prescription medications to help strengthen bones
These steps can reduce your risk of future fractures and help you stay active and independent.
Take the first step
Healthy bones are essential for maintaining your mobility and quality of life as you age. At WMCHealth, bone density testing is available through our imaging services, with follow-up care coordinated through primary care and specialty providers when needed.
If you’re concerned about your risk for osteoporosis, talk with your healthcare provider about whether a bone density scan is right for you. Early screening can help protect your bones for years to come. Make an appointment with a primary care provider.
