Dr. Onna Lo, MD, is a functional and integrative medicine practice focused on helping women in midlife understand and address persistent health concerns. Serving patients in the San Francisco Bay Area and virtually across California, the practice works with women experiencing fatigue, burnout, brain fog, stubborn weight changes, digestive issues, and hormonal symptoms associated with perimenopause and menopause.

Dr. Lo’s approach considers how hormones, gut health, lifestyle, and cellular health may interact, rather than treating symptoms in isolation. Through the Vitality Renew Method, the practice combines advanced testing, clinical expertise, personalized care plans, and ongoing support. The goal is to help patients identify factors that may be contributing to their symptoms and make informed changes tailored to their individual health history.

Services include a Functional Medicine Program, High Performance Coaching, a Women’s Vitality Reset online course, online group meditation, and a Girls Circle. The site also offers an on-demand workshop, educational blog articles, patient resources, and a store. Prospective patients can schedule a discovery call to learn about care options.
