My Story

I'm Susie Willsher and I work with people suffering with digestive problems and help them to reduce their symptoms, improve energy levels, and enjoy food again.


As a teen and a young woman after following the 80’s trends of “low fat and low calorie” dieting, I felt terrible. I was anxious, my gut symptoms were becoming debilitating, I had recurrent tonsillitis and painful swollen joints in my hands and feet. I was diagnosed with irritable bowel syndrome (IBS), which was really not very helpful and all the medication I tried either didn’t help or gave me other side effects. So I did my own research on food and lifestyle and back then there was much less available information. But I managed to improve my IBS, put a stop to the recurrent tonsillitis and my hands and feet went back to normal.


I really wanted to help others who suffered the same so I went back to university and studied nutritional therapy. Thirteen years on and I have helped hundreds of people improve their health and symptoms through personalised diet and lifestyle changes and I love empowering people to take control of their own health.

My Approach

My training and clinical practice is based on a functional medicine model which is a science-based and a patient-centred approach, that aims to explore underlying mechanisms of diseases and symptoms. By looking for the root of the problem, I'm able to see each patient on an individual level, where similar causes may manifest in different symptoms and where different causes may manifest in similar symptoms.


I believe that everyone’s health will benefit from making positive changes to their diet and lifestyle, no matter how small.


I love learning about health and the human body. It never fails to amaze me how much more there is to discover. We are in a time where research is moving fast, so I base my practice on current scientific research and understanding of physiological functions as well as my wide experience with my clients.

My Qualifications

I'm Registered Nutritional Therapist, with a BSc (Hons) degree in Nutritional Therapy. I graduated in 2008. I am registered with the British Association of Nutrition and Lifestyle Medicine (BANT) and the Complementary and Natural Healthcare Council (CNHC). I have been in clinical practice for over 12 years and have appeared on numerous  BBC radio shows.


As a member of BANT and the CNHC, I'm required to cover many hours of continuing professional development (CPD), which I exceed every year.  I love reading up on new research and attending conferences and webinars to ensure I am fully up to date with current research and practices in health.
