Decode Your Fatigue
A root-cause approach for fatigue driven by gut, immune and nervous system dysfunction.
For people who have tried the standard approaches and are still not getting answers.
Decode Your FatigueRecognition
You've been told your blood tests are normal — but you feel anything but
Your energy crashes without warning, regardless of how much you sleep
You're exhausted by midday and running on caffeine just to function
You've seen multiple practitioners but still have no clear answers
You've tried diets, supplements, maybe therapy — nothing holds
Brain fog makes it hard to think clearly or stay present
You're starting to wonder if this is just how life is now
You don't feel believed — or you've stopped trying to explain it
This wasn't bad luck. This was a system under strain — and no one had explained why.
The Case Profile
Most people never get a clear picture of what's actually driving their fatigue. This takes 5–8 minutes — and gives you one. Three clinical layers: symptom burden, nervous system regulation, and developmental health history. Download your results at the end.

Fatigue rarely comes from a single system. This widely used clinical screening tool assesses your overall symptom burden — and how your nervous system may be contributing. Rate each symptom from 0 to 4. Takes about 2 minutes.

Nervous System Regulation
This section goes beyond the standard MSQ. These questions capture nervous system dysregulation patterns that are frequently missed in conventional assessment but are clinically significant in chronic fatigue.
0 = Never / Not at all · 1 = Occasionally / Mild · 2 = Occasionally / Moderate · 3 = Frequently / Moderate · 4 = Frequently / Severe

The Problem
Most fatigue approaches focus on sleep, diet and stress management. For many people, that's enough. But in complex, chronic cases, fatigue is driven by deeper interacting systems — which is why standard approaches don't hold.
Fatigue is a symptom. Without identifying what's driving it — gut dysfunction, toxin load, immune activation — the symptom keeps returning.
Standard blood tests miss the majority of root-cause drivers. Mycotoxins, gut dysbiosis, mitochondrial dysfunction and HPA-axis dysregulation don't show up on a basic panel.
The systems driving chronic fatigue interact with each other. Treating one without the others rarely produces lasting change.
The Framework
After 15 years working with complex fatigue cases, these are the six systems I investigate in every case:
Impaired nutrient absorption, intestinal permeability and gut dysbiosis drive systemic inflammation and block the raw materials energy production depends on.
Mycotoxins, heavy metals and environmental chemicals interfere directly with mitochondrial function — the engine of cellular energy.
Chronic viral, bacterial or parasitic load places a sustained demand on the immune system, depleting energy reserves over time.
HPA-axis dysregulation and autonomic dysfunction disrupt the body's energy regulation — producing the "wired but exhausted" pattern.
Ongoing exposure to mould, toxins or allergens continuously re-triggers the inflammatory response, preventing recovery regardless of other interventions.
Cortisol dysregulation, adrenal exhaustion, low thyroid output and sex hormone imbalance all directly suppress energy production and amplify fatigue.
Very few disciplines are as effective as functional medicine and nutritional therapy at supporting all of these systems simultaneously — which is essential, because in chronic fatigue, they don't operate in isolation.

Client Voices
I have been dealing with mould-related illness for over seven years without finding meaningful help elsewhere. Working with Paul has been one of the best decisions I have ever made. I feel more energetic, more relaxed, and less fatigued.— Male client · Mould toxicity · Chronic fatigue
After years of persistent fatigue and low mood, working with Paul was different from the outset. Over ten months, my energy returned, the anxiety reduced significantly, and my motivation and confidence rebuilt steadily. I feel like myself again.— Female client · Hashimoto's · Chronic fatigue · Anxiety
Since working with Paul, I've seen a significant improvement in my health and would highly recommend his approach.— S.T. · ME/CFS · Chronic fatigue · Cognitive function
The Process
01
A comprehensive functional assessment — advanced lab testing, detailed history, symptom mapping — to identify exactly what is driving your fatigue.
02
A clear picture of which systems are contributing, how they interact, and what has been missed by previous approaches.
03
A fully personalised, phased programme — diet, supplementation, nervous system and lifestyle — designed around your specific findings.

Getting Started
If you've spent months trying to explain how you feel — and still don't have a clear answer — this call is for you.
A structured conversation to understand your case, identify the most relevant underlying drivers, and determine whether a full investigation is appropriate.
For people with persistent fatigue who haven't found clear answers — despite previous tests or treatments.
This is not a generic consultation.
This is the beginning of a case review.
If appropriate, the next step is a full case review — where we investigate these patterns in depth.
