How Accurate Are DEXA Scans? | Dr. Susan Brown | The Girlfriend Doctor Show Ep. 265
•March 19, 2026
Why It Matters
Re‑framing bone health around functional strength and diet reduces reliance on costly imaging and prescription drugs, improving long‑term wellness for aging populations.
Key Takeaways
- •Muscle strength directly predicts bone health and fracture risk.
- •Acid‑alkaline dietary balance supports kidney function and bone resilience.
- •Traditional diets rich in minerals reduce osteoporosis prevalence worldwide.
- •DEXA scans have limitations; functional strength matters more.
- •Natural bone health relies on exercise, nutrition, and stress management.
Summary
The episode of The Girlfriend Doctor Show features Dr. Susan Brown discussing how accurate DEXA scans are and why bone health should be evaluated through functional measures rather than solely imaging.
Brown argues that muscle strength is the primary predictor of bone integrity, that acid‑alkaline balance—driven by kidney function and dietary minerals—protects bone mineral loss, and that DEXA’s focus on density overlooks these dynamic factors.
She cites her 101‑year‑old grandmother’s fracture, the quote “show your body you need strong bones,” and cross‑cultural data showing low fracture rates in traditional societies consuming mineral‑rich, alkalizing foods like potassium citrate vegetables.
The conversation suggests clinicians and consumers shift from calcium‑only supplements to integrated strategies—weight‑bearing exercise, alkalizing nutrition, stress reduction—to prevent osteoporosis, especially for women approaching menopause.
Original Description
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.
