Persistent Gut Symptoms: What Can Testing Actually Tell Us?
Inside RESET, the first pillar of the Gut Rewire Protocol
In the first article in this series, I looked at why persistent gut symptoms can benefit from a more structured approach. Now we're going inside RESET, the first pillar of the Gut Rewire Protocol, to look at what testing can tell us, and just as importantly, what it can't.
Persistent Gut Symptoms Give Us Clues.
They Don't Always Tell Us What's Driving Them.
Bloating is a good example. Two people can both experience bloating after meals, but that doesn't mean the same thing is happening underneath.
One person's bloating may sit alongside reduced digestive capacity, while another may have changes in their microbiome or slower gut motility. Diet, medications, stress and previous surgery can add further pieces to the picture.
The Bigger Picture
The same applies to reflux, constipation, diarrhoea, and food reactions. The symptom tells us where to start asking questions. It doesn't necessarily give us the answer.
That's where clinical assessment and functional testing can help.
Building a Clearer Picture
Rather than relying on one test or one type of information, I look at four different parts of the picture and, importantly, how they fit together.
Your Story
Your health history, symptoms, diet, medications, lifestyle, and what you've already tried
Gut & Microbiome
Information about the gastrointestinal environment, digestive function, and microbial patterns
Pathology
Relevant blood and other pathology that helps us look beyond the gut in isolation
Genetics
Information about individual biological differences that may help us ask more targeted questions
Your Story Is Data Too
A laboratory result without context is just a number. The clinical question is whether it helps us better understand what's happening for you.
Before looking at a lab result, I want to understand the person it belongs to. When did your symptoms start? What was happening around that time? What makes them better or worse? Have you had abdominal surgery? What medications and supplements are you taking?
These details can change the significance of what appears on a test.
You Don't Have to Wait for the Results
Testing takes time, but that doesn't mean nothing happens while we're waiting.
From Day One
You'll have access to the online resource hub: fact sheets, recipes, and practical guides to help you start building useful foundations.
You also have access to me via Voxer between consultations, so questions don't have to wait until your next appointment.
When Results Arrive
Your individual treatment plan is drafted once we've gathered and interpreted the information we need.
The waiting period is not wasted time - it's an opportunity to lay the groundwork before active treatment begins.
What Can Gut & Microbiome Testing Tell Us?
Comprehensive stool testing gives us another view of the gastrointestinal environment. The question is always which findings are meaningful when considered alongside your symptoms and history. More findings don't automatically mean more treatment.
Digestive Function
How well are the various aspects of digestion appearing to function?
Microbial Patterns
What does the bacterial environment look like, and are there findings worth exploring further?
Intestinal Environment
What can relevant markers tell us about what's happening within the gut?
Immune & Inflammatory Activity
Are there findings that change our priorities or warrant further investigation?
What About Pathology and Genetics?
Pathology
Gut symptoms don't occur in isolation from the rest of the body. Depending on your circumstances, pathology may help us look at nutritional status, metabolic health, and other physiological factors relevant to the bigger picture.
Genetics
Your genes don't tell us what is causing your gut symptoms. A genetic result is not a diagnosis. But DNA testing can highlight biological differences that may influence the environment in which your gut and microbiome operate.
This is where nutrigenomics, the study of how our genes interact with nutrition and other environmental factors, can add another layer to the picture.
Concrete Example - The FUT2 Gene
Take the FUT2 gene. This is a common variation that influences whether certain sugars are secreted onto the surface of the gut, which can influence the environment for particular gut bacteria.
You wouldn't know your FUT2 status from your symptoms alone.
But if that genetic finding sits alongside particular patterns in your microbiome testing, diet, and health history, it may give us another piece of the puzzle.
The Important Part Happens After the Test Results Arrive
Ordering tests is relatively straightforward. Interpreting all of them together is the more important part. Imagine your results give us ten different findings: do we create ten different treatments? No. Instead, I look for relationships.
What fits?
Which findings make sense alongside your symptoms and history?
What matters most?
Which findings make sense alongside your symptoms and history?
What can wait?
Not every finding needs to become an immediate treatment priority
Where do we start?
What is the most logical starting point without changing everything at once?
Why Not Change Everything at Once?
When you've been dealing with symptoms for a long time, there's an understandable temptation to tackle everything simultaneously.
The Problem with Doing Too Much
If you cut out dairy, start a probiotic, add digestive enzymes and introduce a fibre supplements all at once, and then feel better, what helped?
If you feel worse, what caused it?
This is also how people can end up in a cycle of trial and error.
The Phased Approach
This is one reason the Gut Rewire Protocol is phased: make a considered change, observe what happens, review, then decide what comes next.
No test can tell us everything about your gut health. Testing can reduce some of the guesswork. It doesn't eliminate uncertainty.
RESET: Building the Foundations
Testing helps us decide where to start. But RESET isn't only about gathering information.
The first pillar of the Gut Rewire Protocl focuses on settling active symptoms, reducing irritation and supporting the gut lining, creating a stronger foundation for the work ahead.
What that looks like will depend on what we've learned from your symptoms, health history and test results. Rather than applying the same starting protocol to everyone, treatment is targeted to the areas that appear most relevant to your individual picture.
The aim isn't to tackle everything at once. It's to work out what matters most, stabilise the gut and start there.
Next: REBUILD
Once we've established that foundation, the next question is how well digestion itself is functioning.
In the next article, we'll move on to REBUILD - the second pillar of the Gut Rewire Protocl and look at stomach function, digestive enzymes and bile, and why what happens before food reaches the microbiome matters.
Have You Looked at HOW You've Been Approaching Your Gut Health?
Testing can tell us more about what is happening physiologically. But there's another part of the picture: how you've been approaching your gut health.
We all develop strategies for dealing with ongoing symptoms. Those strategies can be useful, but when we rely on them too heavily, they can sometimes keep us repeating the same patterns rather than moving forward.
The free Gut Strategy Decoder takes two minutes and helps you identify your strategy, where it may be helping, where it may be less useful, and a practical next step.
