About Dr. Micah Yu
I’m Dr. Micah, I’m a Triple Board Certified Rheumatologist and Autoimmune Warrior and have a private practice called Dr. Lifestyle in Newport Beach California where I see patients worldwide. I was diagnosed with autoimmune disease at a young age but found out ways to eventually use food as medicine and fight my disease. When I changed my diet to more plant based in 2018, I experienced first-hand the power of food for healing diseases. This changed me not only as a patient, but as a doctor. Now I am fighting for autoimmune warriors all over the world and trying to find out “What else can I do to treat autoimmune diseases?”
Because of my disease and personal journey navigating the integrative side of medicine, I created MYAutoimmuneMD to help people around the world navigate difficult autoimmune diseases as it can be a complicated journey.

I graduated with a Doctor of Medicine at Chicago Medical School in Illinois.
After medical school, I went on to complete my Internal Medicine Residency and Rheumatology Fellowship at Loma Linda University in Southern California.
Because I felt that my conventional medicine training wasn’t enough, I further educated myself on other forms of treatments.
