🦴 DEXA Scan (Bone Density Scan)

A quick, low-radiation scan used to assess bone strength and the risk of fractures or osteoporosis.

🔍 What is it?

A DEXA scan (Dual-energy X-ray absorptiometry) measures bone mineral density (BMD) in areas like the spine, hips, and wrists. It helps detect osteoporosis before a fracture happens and tracks treatment effectiveness.

🧪 What does it show?

• Bone density levels
• Risk of fractures
• Early signs of osteoporosis or osteopenia
• Response to bone-strengthening treatments

❓ Why might I need it?

👵 Post-menopausal or older age
💔 History of fractures or family history of osteoporosis
💊 Long-term use of steroids or certain medications
⚖️ Low body weight or eating disorders
🏥 Conditions like rheumatoid arthritis or thyroid disorders

🧬 Conditions it can help detect:

• Osteoporosis
• Osteopenia
• Bone loss from medication or chronic illness
• Secondary bone disorders (e.g., hormone imbalance)
