About Dr. Onna Lo MD
Functional Medicine Physician and Creator of Unstuck Medicine™
Dr. Onna Lo MD is a functional medicine physician and creator of Unstuck Medicine™, a root-cause methodology for high-achieving women recovering from burnout, hormonal imbalance, and chronic fatigue in the SF Bay Area and virtually across California.
She specializes in helping ambitious women
executives, entrepreneurs, and driven professionals in their midlife — break free from chronic fatigue, hormonal imbalance, brain fog, and burnout. These are women who are succeeding by every external measure but running on empty on the inside, often dismissed by conventional medicine and quietly wondering whether this is just how midlife feels.
Unstuck Medicine™
Dr. Lo is the creator of Unstuck Medicine™ — a root-cause methodology built on a simple but powerful premise: most women are stuck. Stuck in a system that treats symptoms, not causes. Stuck in a body that's changed and a medical system that hasn't caught up. Through her structured four-step process — Reveal, Remove, Rebalance, Renew — and four interconnected root systems (Lifestyle, Hormones, Gut, and Cellular health), she finds what conventional medicine misses and builds a clear, personalized path forward. The result isn't just symptom relief — her patients understand exactly what was off, they know how to get well, and continue to stay optimized for years to come.
Ivy League-trained
Dr. Lo studied at Warren Alpert Brown University Medical School and fellowship-trained in Integrative Medicine at UCSF Santa Rosa. She holds board certifications in Family Medicine (ABFM) and Integrative & Holistic Medicine (ABIHM, ABOIM), with advanced training in acupuncture, craniosacral therapy, and mind-body medicine. She is a member of the Institute for Functional Medicine (IFM), Menopause Society and brings both clinical precision and lived experience to her work. Based in the SF Bay Area, she works with women throughout California, in person and virtually
From Burnout to Breakthrough
As a driven, Type A achiever, she spent years excelling in high-pressure environments—first growing up in Hong Kong, then earning a place at medical school straight out of high school. She pushed through her own decade of debilitating migraines, asthma attacks, gut issues, and burnout — and rebuilt her health from the inside out. She has personally navigated through burnout, chronic illness, and recovery through these very methods she now uses with patients.

Success Stories
“I had been battling Ankylosing spondylitis for over 15 years ... After 3 months (working with Dr. Lo) I have lost 22 pounds, improved my sleep, my pain has significantly improved as are my GI system and my skin. On top of that, I have been able to discontinue three medications! I am still in the restoration phase of my treatment plan and am continuing to feel better every day.”
