I’m Debra Thomas, a UK Specialist IBS & low FODMAP Dietitian. I help people who’ve been dismissed, confused, or stuck finally understand what’s driving their IBS and take control of their symptoms.
After working with thousands of clients, one thing became clear to me. Many people with IBS are not getting the right guidance or support.
I’m HCPC registered, a member of the British Dietetic Association, and have over 20 years of experience helping people manage Irritable Bowel Syndrome (IBS).
But what matters more than my credentials is this:
I know how frustrating it is to live around your gut.
It’s not 'just' IBS
IBS is real — and it deserves evidence-based, practical support.
Through this work, I developed a clear and proven way to help people feel better with more confidence and less guesswork.
I’m a Registered Dietitian, regulated by the Health and Care Professions Council (HCPC) and a Member of the British Dietetic Association (BDA).
I trained in the low FODMAP approach at King’s College London, and spent many years within the NHS working in Nutrition Support, and Specialist IBS Services.
For the last 10 years, I’ve worked with clients across the UK, helping them reduce IBS symptoms and rebuild a normal relationship with food.
I have a base in Cardiff and Bristol, but support clients online across the UK, combining clinical expertise with a warm, practical approach that fits into real life.
My approach blends medical nutrition therapy, the low FODMAP method, and everyday guidance. It’s not about restriction, it’s about confidence and lasting relief.
This approach is designed to help you move from frustration and confusion to clarity and control.
Every person’s IBS is different, but the roadmap to relief follows three key steps:
We review your symptoms and triggers so you know exactly what’s happening.
Together, we build a low FODMAP plan that fits your life — not the other way around.
You’ll get guidance and feedback every step of the way to make results last.
If you are wondering whether this approach really works, here is what clients have shared about their experience.
Debra has genuinely changed my life — my IBS symptoms have virtually gone, and I’ve learned a new, enjoyable way of eating.

After years of pain and fatigue, I followed Debra’s FODMAP plan — within days my symptoms disappeared. I’ve since lost weight, regained energy, and even started running again.

I also work closely with other Specialist Dietitians, so you are supported by the right expertise whenever it is needed.
As a member of the South Wales Freelance Dietitians’ Group, I work alongside a trusted network of professionals who specialise in different areas of nutrition and health.
This collaboration means my clients can benefit from wider expertise when needed — from paediatrics to sports and mental health nutrition.
Outside of work, I value exploring new places, learning new things, and pushing myself beyond my comfort zone.
Outside of work, I enjoy walking in the countryside, travelling, and reading. I also like pushing myself outside my comfort zone, whether that’s skydiving, exploring new places, or taking on challenges that require planning and resilience.
That mindset carries into my work with clients. IBS can feel unpredictable and overwhelming, so I focus on providing clear guidance, steady support, and a plan you can trust, so managing symptoms feels manageable rather than stressful.
If you are ready to take the next step towards feeling more like yourself again, this is how we can start.
We’ll discuss your symptoms, your history, and whether my approach is right for you.
