Dr Karen Coates is an internationally respected women’s health doctor, educator, and author, known for her ability to translate complex medical science into practical, life-changing guidance for women. She lectures globally on nutrition, hormones, and longevity, and is a regular seminar leader at Australia’s leading health retreat and World’s Best Eco Spa, Gwinganna.

​

With more than three decades of clinical experience, Dr Karen has worked as a medical doctor and herbalist, supporting women through every stage of their hormonal journey. In November 2026, she released her third book, Hormonal Harmony – A Guide for Women, further cementing her reputation as a trusted voice in women’s health.

​

Dr Karen holds degrees in medicine and surgery, with postgraduate qualifications spanning nutrigenomics, obstetrics, and nutritional and environmental medicine. Her work sits at the intersection of science, lifestyle, and longevity.

​

She is deeply passionate about helping women optimise fertility, hormones, metabolic health, and long-term wellbeing. This passion has shaped her personal mission: to empower women with the knowledge and tools to take confident control of their health and feel well for longer.

When she’s not immersed in research, writing, or working with clients, Dr Karen is usually planning her next European adventure, pottering in the garden with the family dog, or soaking up some sunshine on the back deck — ideally accompanied by a square of dark chocolate and a very good book.
