How Accurate Are DEXA Scans? | Dr. Susan Brown

Are DEXA scans really the gold standard for measuring bone health—or could they be misleading you?

In this eye-opening episode of The Girlfriend Doctor Podcast, Dr. Anna Cabeca sits down with medical anthropologist and certified clinical nutritionist Dr. Susan Brown to unpack the truth about bone density testing, osteoporosis fear, and what truly supports lifelong bone strength. Many women are told their bones are deteriorating based on a single scan—but according to Dr. Brown, the story is often much more complex. Together, Dr. Anna and Dr. Brown explore the limitations of DEXA scans, why results can vary widely depending on calibration and technique, and how women can take a more comprehensive, natural approach to protecting their bones. Dr. Brown shares insights from decades of research on alkaline nutrition, mineral balance, movement, and whole-body health, revealing why bone health is about far more than calcium alone.

In This Episode, You’ll Learn:

• Why DEXA scans can have significant margins of error and how calibration affects results

• The biggest misconceptions about osteoporosis and bone density testing

• How pH balance and an alkaline-supportive diet influence bone health 

• The critical role of muscle mass, movement, and weight-bearing exercise in building stronger bones

• Why 20 essential nutrients—not just calcium—are required for optimal bone strength

• Practical ways to support bone regeneration naturally during perimenopause and menopause

Dr. Brown’s pioneering work has helped thousands of women move beyond fear-based bone diagnoses and take a proactive, science-based approach to building stronger bones for life. If you’ve ever been confused—or worried—about your bone density results, this conversation will empower you with a deeper understanding of what your bones truly need.
