Ostrolenk speaks with Dr. Lacey Chittle, a functional medicine specialist in the San Francisco Bay Area. Chittle explains functional medicine, a root-cause approach to treating medical conditions. Chittle's own experience with autoimmunity, IBS, chronic pain and fatigue lead her to discovering the immense benefits of functional medicine, an experience that inspired her to practice functional medicine in treating her patients. Chittle also discusses the transition of conventional medicine towards adopting the approaches of functional medicine. To learn about Dr. Chittle's work, visit her website at www.drlaceychittle.com/.
