DXA Scans: Your Key to Osteoporosis Prevention

Dual-energy X-ray absorptiometry, or DXA scans, are important imaging tests for evaluating bone health. Primarily used to determine an individual's risk of osteoporosis and fractures, these scans measure the strength and mineral content of bones, especially in the hip and spine. Broken bones in older adults can signify the beginning of serious health issues and lead to long-term disability.

Beyond bone density, DXA scans also offer a detailed assessment of body composition. They can identify fat percentage, track where fat is distributed, and measure muscle mass. This information is valuable as body composition can be a better indicator of overall health than simple body weight alone.

DXA scans are recommended for women aged 65 and older and men aged 70 and older. Younger adults with risk factors such as a history of fractures, long-term steroid use, or a family history of osteoporosis should also consider a scan. Osteoporosis is often called a 'silent disease' as it is usually detected only after a fracture occurs. Pregnant individuals are generally advised to postpone the examination due to the use of ionizing radiation.
