The Practitioner Behind The Methodology
Experience You Can Trust.
A Methodology You Can Understand.
Douglas Mizzi has spent more than three decades helping people make sense of their health. As a clinical nutritionist, he has completed over 65,000 consultations — always with the same belief: people deserve to be listened to, and to understand what is happening in their own body.
At The Reflux Clinic, that experience is focused on reflux, GORD and ongoing digestive symptoms — looking beyond the surface to the patterns and drivers behind how you feel.

The Story Behind The Methodology
Over more than thirty years in clinical practice, Douglas noticed the same thing again and again: people arriving frustrated, having been told their symptoms were “normal” or simply managed with medication, without anyone ever explaining why they felt the way they did.
Reflux is one of the clearest examples. So often it is treated as a single problem to suppress, when in reality it is a signal — shaped by diet, timing, stress, lifestyle and individual physiology. Understanding those drivers is what makes lasting change possible.
That belief became a methodology: listen first, investigate thoroughly, educate clearly and build a plan around the individual. It is the same approach that has guided tens of thousands of consultations — and it is the approach behind The Reflux Clinic.
“People don’t just want to be treated — they want to be heard, and they want to understand their own body.”
A Different Kind Of Practitioner
What it actually feels like to be a client at The Reflux Clinic.
Listening First
Your story matters. Every consultation begins by genuinely listening to your experience — not rushing to a label.
Time To Understand
Unhurried appointments mean there is space to explore what is really happening, rather than a five-minute fix.
Education, Not Just Advice
You leave understanding why your symptoms occur and what to do — so you feel in control, not dependent.
Investigative Approach
Reflux is often a signal, not the whole story. We look for the patterns and drivers behind your symptoms.
Personalised Plans
No two people are the same. Your plan reflects your body, your routine and your goals — never a template.
Families & Individuals
From individuals to whole families, care is tailored to real lives and everyday routines.
Looking Beyond The Surface
Reflux rarely has a single cause. Douglas works through five layers to understand the full picture.
Symptom Presentation
How your reflux, heartburn, bloating or discomfort actually shows up — when, how often and how severe.
Clinical History
When symptoms began, how they have changed, and what has been tried so far — including medications and investigations.
Lifestyle Investigation
Meal timing, stress, sleep, activity and daily rhythm — the everyday factors that shape digestion.
Dietary & Trigger Patterns
The foods, habits and combinations most likely to be aggravating your reflux and digestive symptoms.
Recovery Capacity
How well your body is placed to settle and recover — and what support will help it get there.
