DEXA Scan guide
Compare London providers offering DEXA scans for body composition, visceral fat, lean mass and bone-density assessment.

Useful when you want a more detailed view of fat mass, lean mass and regional distribution than consumer scales provide.
Some providers report visceral fat alongside total and regional body composition.
Clinical DEXA is also used to assess bone mineral density, although the purpose and reporting format may differ from fitness-led scans.
Science-informed guide
Practical notes to help you understand the likely benefits, limits and timing considerations before booking. This is not medical advice.
DEXA uses low-dose X-rays at two energy levels to estimate bone mineral density and body composition.
A body-composition scan and a clinically indicated bone-density assessment may use similar technology but answer different questions.
Check which outputs are included, who explains the results and whether repeat scans use a consistent protocol.
DEXA is a measurement tool, not a diagnosis or a complete assessment of metabolic health.
How to choose
You usually lie still on an open scanning bed while the arm passes over the body.
Outputs may include total body fat, lean mass, regional balance, visceral fat and bone-density measures.
Some services provide only the report; others include a physiologist or clinician review.
We are still checking London providers for this guide. Only venues with a clearly stated matching diagnostic or assessment service will appear.
How to choose
Check whether the booking is designed for body composition, bone density or both.
Confirm the report, consultation, repeat-scan comparability and any preparation requirements.
A cheaper scan may be sufficient for tracking, while a clinically relevant concern may require qualified interpretation and referral pathways.

Questions
Depending on the service, a DEXA scan can report bone mineral density, total and regional body fat, lean mass and estimated visceral fat.
No. DEXA uses medical imaging technology and generally provides more detailed regional estimates than bioimpedance scales, although every measurement method has limitations.
Many private body-composition services accept direct bookings. Clinically indicated bone-density scans may follow a different referral or review process, so check with the provider.
