What is a Bone Density Scan (DEXA, DXA)?
Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today's established standard for measuring bone mineral density (BMD).
The National Osteoporosis Foundation (NOF) recommends that all women over 65 or postmenopausal age with risk factors talk to their doctors about a bone mineral density test (BMD) to diagnose osteoporosis. Women who are younger than 65 years and past menopause should have a BMD test if they have had a bone fracture because of fragile bones or have other risk factors for osteoporosis, such as rheumatoid arthritis, smoking, alcoholism, a history of hip fracture in a parent, or a body weight less than 127 pounds.
The following factors cause or contribute to osteoporosis and fractures:
- Certain medications
- Diseases such as inflammatory bowel disease, rheumatoid arthritis (RA), and lupus
- Low calcium intake
- Vitamin D insufficiency
- Excess vitamin A
- High caffeine intake
- High salt intake
- Aluminum (in antacids)
- Alcohol (three or more drinks per day)
- Not getting enough physical activity or being immobile
- Smoking (including secondhand smoke)
- Being thin
