Your Diagnosis Isn’t The Root Cause | Dr. Will Cole

Mental Health

September 10, 2026

What if the anxiety, brain fog, fatigue, intrusive thoughts, or dysregulation you’re experiencing isn’t coming exclusively from your thoughts?

And what if a physical symptom isn’t exclusively physical either?

S3 EP. 005

In this episode of Decoded, Elisabeth McKay sits down with functional medicine expert Dr. Will Cole to examine the intersection between mental health, cellular health, inflammation, hormones, environmental exposures, gut health, and behavioral patterns. The central question is one that conventional conversations often separate into competing camps: Is the origin of a symptom physiological, psychological—or both?

Dr. Cole explains how functional medicine approaches that question through comprehensive lab testing, tighter functional ranges, health history, and bio-individuality. They discuss cellular aging, mitochondrial dysfunction, metabolic health, thyroid function, environmental toxins, mold, intrusive thoughts, trauma, peptides, IV therapy, and why receiving a diagnosis still doesn’t necessarily explain the mechanism that produced it.

They also get into the philosophy behind longevity. Dr. Cole distinguishes extending healthspan from the pursuit of immortality and discusses the spiritual dimension of health explored in his new book with Dr. Josh Axe, Heal Yourselves: Reversing the Irreversible.

In this episode:

  • Mental health symptoms and cellular dysfunction
  • Why mental health and physical health aren’t separate systems
  • Intrusive thoughts and neuro-immune-endocrine dysregulation
  • What functional medicine actually is
  • Optimal lab ranges vs. conventional reference ranges
  • Why the same diagnosis can have different underlying mechanisms
  • Autoimmunity, thyroid function, and metabolic health
  • Cellular aging and mitochondrial function
  • Mold, biotoxins, heavy metals, pesticides, PFAS, and microplastics
  • Stress, trauma, shame, and physiological dysregulation
  • Healthspan vs. the pursuit of immortality
  • The spiritual component of longevity
  • Biomarkers Dr. Cole looks at when evaluating cellular health
  • Why peptides are a tool—not a substitute for addressing underlying dysfunction
  • When IV therapy may be useful and when it may simply become an expensive bandage

The point isn’t to decide that every psychological symptom is secretly physical—or that every physiological symptom can be changed through thought.

It’s to stop forcing the human body into an either/or framework when the systems affecting your behavior, emotions, brain, immune function, hormones, and cellular health are constantly interacting.

Watch the full conversation and ask a better question: What is actually upstream of the symptom you’re trying to change?
