About

Director of London Nutrition Doctor, Dr Leah Austin is a Private General Practitioner and Nutritional Therapist.


Dr Leah Austin graduated from Newcastle University upon Tyne in 2007 and completed her General Practitioner training in the Northern Deanery. She completed posts in general medicine, emergency medicine, microbiology, palliative care, and obstetrics and gynaecology. Since working as a General Practitioner she has gained experience working in the North East, Yorkshire and London.

Working as General Practitioner within the NHS, she became frustrated with time constraints of 10 minute consultations; the ability to manage patients with longstanding (chronic) health problems and really being able to give patients the individualised assessment and care they deserved.

Being of mixed ethnic background with Chinese and English, she became fascinated with eastern medicine and the true impact of nutrition, genetics, herbs, environment and lifestyle. With this and her own health/family concerns; led her to study nutrition and qualify as a Nutritional Therapist in September 2017 at the College of Naturopathic Medicine.

She uses a systems-oriented, 360 degree approach (lifestyle, nutrition, medical, genetic, environmental) to address her clients/patients health concerns to ultimately produce the best plan/programme and protocols.

Over the years, she continues to learn from top practitioners and specialists in their field to maintain her understanding of the latest research, so that she is able to educate and give the best care to her clients/patients.

Having moved to London in 2014, Dr Austin joined Private Practice in September 2016 and also continues to provide out of hours care for the NHS. She is qualified, maintains her GMC registration and has licence to practice.
