Migraines and chronic headaches can be life-disrupting, painful, and complex to treat. While conventional approaches rely on pain relievers, functional medicine searches for the underlying causes—ranging from hormonal imbalances and food intolerances to poor detoxification, nutrient deficiencies, mold exposure, or even gut-brain axis dysfunction. Functional medicine tailors a root-cause plan that can reduce frequency and severity, restore nervous system stability, and help patients regain control without overdependence on medication.
