Kim K and the DEXA scan: what to know

DEXA stands for dual-energy X-ray absorptiometry. The scanner uses low-dose X-rays to assess bone density, commonly at the hip and lower spine. The result is interpreted alongside your age, medical history, medicines, previous fractures, and other risk factors. A scan can support assessment of osteoporosis or reduced bone density, but it is not a complete picture of bone health and does not predict an individual event with certainty. Premature ovarian insufficiency, some medicines, and conditions affecting hormone levels can influence why a clinician recommends assessment.

Follow the imaging centre’s instructions and tell staff if you may be pregnant, have recently had contrast imaging, or have metal that could affect positioning. Wear clothing that allows comfortable positioning and remove items requested by the team. During the scan, you lie still while the scanner passes over the selected areas; the technologist may help position your legs or hips. The test does not require a tunnel, and you can usually leave afterwards. Your clinician will explain the result and whether lifestyle measures, repeat assessment, or treatment should be considered.

A DEXA scan is usually arranged as a planned assessment, not an emergency test. Contact a clinician promptly after a new fracture, sudden severe back or hip pain, loss of height, or difficulty walking, particularly if you have known low bone density. Seek urgent help after a serious injury, inability to bear weight, or new weakness or numbness. These symptoms need examination because a scan appointment alone cannot assess every cause of pain.

Ask why the scan is recommended, which body areas will be assessed, and how to interpret the report. Discuss medicines and health conditions that may affect bone density, whether you need fracture-prevention advice, and when your result should be reviewed.
