Micah Yu, MD

Dr. Micah Yu, MD is an integrative rheumatologist who combines conventional rheumatology with lifestyle, functional, and integrative medicine to support patients with complex autoimmune and inflammatory conditions.

He is quadruple board-certified in Rheumatology, Internal Medicine, Integrative Medicine, and Lifestyle Medicine. Dr. Yu earned his medical degree from the Chicago Medical School and holds master’s degrees in Healthcare Administration and Biomedical Sciences. He completed his Internal Medicine residency and Rheumatology fellowship at Loma Linda University and is a graduate of the Andrew Weil Center for Integrative Medicine Fellowship at the University of Arizona. He is also certified in Functional Medicine through the Institute for Functional Medicine.

Dr. Yu is an active member of professional organizations focused on complex and environmentally driven illness, including the International Lyme and Associated Diseases Society (ILADS), the International Society for Environmentally Acquired Illness (ISEAI), and the American Academy of Environmental Medicine (AAEM).

What sets Dr. Yu’s care apart is his personal understanding of autoimmune disease. Diagnosed with gout at age 17 and later with spondyloarthritis, he brings both clinical expertise and lived experience to every patient interaction. This perspective allows him to approach care with empathy, curiosity, and realism.

He is the co-owner of Dr. Lifestyle, a private practice based in Newport Beach, alongside his wife, Dr. Melissa Mondala. He creates educational content under the handle @myautoimmunemd across YouTube, Instagram, Facebook, and TikTok, and is also the co-host of the podcast Autoimmune Alchemy.
