Dr. Shiyan Ooi is a General Practitioner in Singapore with over a decade of experience, driven by a personal understanding of health challenges. Her own past struggles with burnout, hormonal imbalance, and gut issues fueled a deep commitment to holistic healing and a belief in the body's capacity for optimization.

A Bachelor of Medicine and Surgery (MBChB UK) from the University of Manchester laid the groundwork for her career, which includes experience in the UK's NHS, Singapore government hospitals, and private clinics. This varied background provides her with a broad view of healthcare, but she is particularly passionate about going beyond symptoms to find the root causes of illness.

Specializing in root cause analysis, Dr. Ooi works with patients to uncover the origins of their chronic conditions. She integrates key areas like hormonal balance, gut health, and lifestyle into her treatment plans, aiming for meaningful and lasting health changes. Her connection with The Institute for Functional Medicine highlights her dedication to a comprehensive, patient-focused model. For Dr. Ooi, helping patients achieve not just freedom from disease, but a state of true physical, mental, and spiritual well-being is the most rewarding part of her work.
