DEXA Body Composition Scan
A DEXA body composition scan estimates fat, lean, and bone by region—best used for scheduled trend checks, not daily weigh-in anxiety.
A DEXA body composition scan uses dual-energy X-ray absorptiometry to estimate fat mass, lean mass, and bone mineral density in regional segments—not just total scale weight. It is more precise than home scales for fat and lean trends when repeated on the same machine and protocol.
Clinicians order scans for osteoporosis and metabolic goals; wellness users track quarterly or biannual trends, not daily noise.
Common questions
-
How often should you repeat a DEXA for body composition?
Every three to six months is typical for trend tracking—long enough for fat and lean shifts to exceed day-to-day hydration noise. Match prep conditions each visit.
