A functional approach means identifying patients with hidden autoimmune disorders and utilizing all the tools to calm the autoimmune attack. Dr. Yu and our Holistic Nutritionist collaborate with you to ensure food intolerances and blood sugar regulation are the key to your success. We also do vitamin testing, hormone testing, and gut infection testing, if necessary ,to ensure all the symptoms of autoimmune attack are diminished. As Dr.Yu frequently says, the zebras in other practices that no one knows how to deal with or dismisses are the typical everyday patient we see here that experience radical changes in their health from our functional approach. Some of the autoimmune conditions we focus on are: Hashimotos, rheumatoid arthritis, infertility, ulcerative colitis, Crohn’s, fibromyalgia..
