What happens when healthcare stops treating organs and symptoms in isolation and starts seeing patients as whole systems? In this conversation with Dr. Erica Armstrong, we confront the limitations of siloed medicine and explore how root-cause functional care can reframe chronic illness, integrate microbiome, inflammation, and nutrition as part of a connected human ecosystem, and unlock new routes to prevention and cost-effective care. This episode spotlights the urgency of convergence care—where oral, medical, and lifestyle insights unify around the patient. It matters now because employers, clinicians, and innovators are increasingly demanding models that move beyond episodic sick care toward systems-level health outcomes.
