About Susie
My story. My passion. Your health.
I'm Susie Willsher, and I help people with digestive problems, hormonal changes, diabetes, and chronic health issues find real answers through personalised nutrition.
I know what it's like to suffer with digestive symptoms and how exhausting it can be. I spent years dealing with them, and they drove me nuts until I finally decided to take action.
As a teenager in the 1990s, I followed every diet trend going, fat, low calorie, anything the magazines said. What I got in return was anxiety, debilitating gut symptoms, recurrent tonsillitis, and painful swollen joints. My GP diagnosed IBS and gave me medication that either didn't work or made things worse.

So I started researching. Properly. I discovered that the foods I was eating (and the ones I wasn't) were driving my symptoms. Through careful changes to my diet and lifestyle, I improved my IBS, eliminated the recurring tonsillitis completely, and restored normal joint function. It was transformative.
That experience lit a fire. I went back to university to study nutritional therapy, graduated with a BSc (Hons), and have spent the last eighteen years helping hundreds of people do what I did, understand their bodies, identify what's driving their symptoms, and make changes that actually stick.
“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're 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 clients.
How I work
My training and clinical practice follows a functional medicine model, science-based and patient-centred.
Root of the problem, not symptom management
I don't just address what's happening on the surface. I look at why it's happening, examining your biochemistry, health history, and lifestyle to find the underlying drivers.
Personalised, not generic
Your plan is built around your body, your life, and your goals. There are no template meal plans here. Every recommendation is specific to you.
Evidence-based, always
I base my practice on current scientific research and clinical experience. I stay up to date through continuous professional development, conferences, and research reading.
