Why Get a DEXA Bone Scan? Understanding Osteoporosis Risk
The Importance of DEXA Bone Scans for Osteoporosis Prevention
As we age, keeping bones strong becomes more important, but without proper screening, osteoporosis can go undetected until a fracture occurs. Fortunately, there’s a simple, non-invasive way to assess bone health before that happens: the DEXA scan.
So, why get a DEXA bone scan? In this post, we’ll explore how this test works, who should consider it, and how it plays a crucial role in preventing serious complications like hip or spinal fractures. We’ll also share practical lifestyle tips for maintaining strong bones for life.
What Is a DEXA Bone Scan?
A DEXA scan (short for dual-energy X-ray absorptiometry) is the most accurate and widely used test to measure bone mineral density (BMD). It uses a very low dose of X-ray to evaluate the strength of your bones, usually at the hips and spine, where fractures are most dangerous.
At Wisteria Imaging, DEXA scans are quick (around 10–15 minutes), painless, and don’t require any special preparation. You lie flat on a table while the scanner gently moves over you: no injections, no discomfort, and no downtime.
Why Get a DEXA Bone Scan?
Osteoporosis is often called a “silent disease” because it progresses without symptoms, until a sudden fracture reveals its presence. A DEXA scan is the only way to detect low bone mass before something breaks.
Reasons to consider getting a DEXA scan include:
You're a woman over 65 or a man over 70
You're postmenopausal and under 65 with risk factors (e.g., small frame, smoking, steroid use)
You’ve had a fracture after age 50
You have a condition like rheumatoid arthritis or take medications that affect bone health
DEXA gives you a T-score that helps your doctor assess fracture risk and determine whether you have osteoporosis or osteopenia (early bone loss). It’s a crucial step in protecting your mobility and independence as you age.
What Happens During the Test?
Before your scan: No special prep is required, but you should avoid calcium supplements for 24 hours beforehand.
During the scan: You’ll lie comfortably on a padded table while a scanning arm moves above you. The process is quiet and painless.
After the scan: You can leave immediately and resume all normal activities. Results are typically available within a few business days and shared with your referring provider.
The amount of radiation used is extremely low, less than a dental X-ray, making DEXA safe even for regular monitoring.
How Often Should You Get a DEXA Scan?
This depends on your bone density and risk level. If your initial scan shows normal bone density, you may only need a repeat every 5 years. If you have osteopenia or osteoporosis, your provider may recommend scans every 1–2 years to monitor progress and guide treatment.

Lifestyle Tips for Stronger Bones
While a DEXA scan helps assess risk, lifestyle plays a huge role in bone health. Here are a few key strategies:
1. Nutrition
Eat calcium-rich foods like leafy greens, yogurt, and fortified cereals
Get enough vitamin D through sunlight or supplements
2. Weight-Bearing Exercise
Activities like walking, hiking, dancing, or strength training help stimulate bone growth
3. Avoid Smoking & Excess Alcohol
Both reduce your body’s ability to absorb calcium and weaken bone structure over time
4. Prevent Falls
Balance training, handrails, and home safety checks can prevent injury, especially as you age
If you’re already at risk or have early bone loss, your doctor may also recommend medications to slow bone breakdown or promote bone formation.
