ADHD Is a Whole-Body Problem: What to Look at Beyond the Brain

In this episode of The Doctor's Farmacy, Dr. Mark Hyman and producer Emma look at ADHD through a functional medicine lens, arguing that the disorder often stems from issues in the gut, nutrient deficiencies, inflammation, and blood sugar imbalances rather than simply a brain-based problem. They discuss how the gut-brain axis influences attention even without digestive symptoms, common nutritional shortfalls that can exacerbate ADHD, and why the same diagnosis can have radically different root causes. The conversation offers practical starting points like stabilizing blood sugar, eliminating food dyes, and working with a functional medicine practitioner to identify personalized interventions. Throughout, Hyman emphasizes that treating ADHD requires looking at the whole body, not just the brain.
