Paul Foley — Functional Medicine Practitioner

Does This Sound Like You?

You’re functioning — but it’s taking
everything you’ve got.

Waking up exhausted despite 8 hours of sleep
The 3pm crash — every day, without fail
Told your bloods are “fine” when you feel anything but
Brain fog that makes simple tasks feel impossible
Living on caffeine just to get through the day
Anxiety or low mood that arrived with the fatigue
You’ve started cancelling things — because you don’t have the energy to show up
You’ve started wondering if this is just how life is now
Pushed through for years — now your body won’t let you
You’ve tried everything. Nothing has stuck.

“This wasn’t burnout. This wasn’t laziness. This was a system under strain — and no one had explained why.”

Why Standard Testing Misses This

Your GP is looking for disease.
We’re looking for dysfunction.

Standard blood tests are designed to rule out serious pathology — anaemia, diabetes, thyroid disease. They are not designed to detect functional imbalance. A result within the reference range is not the same as a result that is optimal for that individual. There is a significant gap between “not diseased” and “functioning well” — and that gap is where most chronic fatigue lives.

Fatigue at this level is rarely driven by a single cause. In clinical practice, it is almost always the result of several overlapping systems under strain simultaneously — the stress response axis, mitochondrial energy production, gut health and inflammation, thyroid function, toxic load, and nutrient status. Standard testing rarely investigates more than one or two of these at a time. Dysfunction in the others continues unchecked.

The approach here is pattern recognition across systems. Not chasing a single abnormal result, but understanding why multiple systems have shifted out of optimal function at the same time — and what the correct sequence of intervention looks like. This is the work that takes time. It is also the work that produces lasting change.

Root Causes We Investigate

Fatigue this persistent has a pattern.
These are the places we look.

HPA-Axis Dysregulation

Your body is stuck in a low-level stress response — even when you’re trying to rest. Cortisol rhythm collapses. Sleep stops restoring. Energy never fully returns.

Mitochondrial Inefficiency

Your cells aren’t producing energy efficiently — so everything feels harder than it should. Basic tasks drain you. Recovery takes longer than it used to.

Gut-Driven Inflammation

A compromised gut doesn’t just cause digestive symptoms — it generates low-grade systemic inflammation that suppresses energy, clouds cognition, and destabilises mood.

Thyroid Dysfunction

TSH within range doesn’t rule out thyroid involvement. Poor T4-to-T3 conversion, reverse T3 dominance, and autoimmune thyroid activity are all invisible to standard panels — and all drive fatigue.

Mycotoxin Burden

Mould exposure is one of the most underdiagnosed drivers of fatigue — particularly in people who haven’t responded to anything else. The toxin load is real. It shows up in testing.

Methylation & Nutrient Status

Even when diet is good, genetic variants in methylation (including MTHFR) can mean your body isn’t processing B12, folate, and other key nutrients efficiently — and energy production suffers as a result.

What Testing Can Reveal

Beyond pass/fail — a performance assessment.

Routine bloodwork rules out major pathology. Functional testing goes further — looking at markers that indicate how well systems are performing, not just whether disease is present. The difference is between a pass/fail test and a performance assessment.

Testing is used selectively here — ordered based on the clinical picture that emerges from a detailed case review, not as a standard package applied to every client. The goal is to confirm clinical hypotheses, not generate a list of results to be interpreted in isolation.

Functional Testing

Comprehensive thyroid panel (TSH, fT3, fT4, rT3, antibodies)
Organic acids panel
Adrenal cortisol mapping (4-point saliva)
Mycotoxin screening
Nutrient status deep-dive (B12, folate, iron, vitamin D)
Gut microbiome analysis

Standard Testing

Full blood count
TSH only
Basic iron panel
"All normal — no further action"

Gap remains unexplained

Poor stamina — energy crashes after mild activity

Category 02

Mind & Cognition

01234

Brain fog — difficulty thinking clearly or concentrating

Poor memory — forgetting words, names, or recent events

Difficulty making decisions or feeling mentally overwhelmed

Category 03

Mood & Nervous System

01234

Anxiety, fear or nervousness

Low mood or depression — persistent flatness or sadness

Mood swings or irritability

Poor sleep — difficulty falling or staying asleep, or unrefreshing sleep

Bloating, gas or abdominal distension after eating

Constipation, diarrhoea or alternating bowel habits

Food sensitivities or reactions after eating

Category 05

Immune & Inflammatory

01234

Frequent infections, slow recovery or immune sensitivity

Joint or muscle aches and pains — not from exercise

Skin issues — eczema, rashes, hives or unusual reactions

Category 06

Hormones & Metabolism

01234

Weight gain or difficulty losing weight despite effort

Cold hands and feet, sensitivity to temperature

Hair loss, thinning hair or poor nail quality

Category 07 — Custom Assessment

Nervous System Regulation

These questions capture nervous system dysregulation patterns frequently missed in conventional assessment but clinically significant in chronic fatigue.

01234

Do you feel "on edge" or wired, even when there's no obvious reason?Captures: sympathetic dominance / baseline tension

Do small stressors feel disproportionately overwhelming or hard to recover from?Captures: low stress resilience / poor recovery

Do you feel tired but unable to fully relax or switch off, especially in the evening?Captures: wired-but-tired pattern

Do you wake during the night or wake up unrefreshed, even after enough hours in bed?Captures: nervous system → sleep → fatigue connection

Do noise, light, screens, or busy environments leave you feeling drained or overstimulated?Captures: limbic sensitivity / sensory load

0 = Never · 1 = Occasionally mild · 2 = Occasionally moderate · 3 = Frequently moderate · 4 = Frequently severe

Client Voices

What clients say

★★★★★

“

I’d been dealing with mould-related illness for over seven years without finding meaningful help. Working with Paul over the past few months has been one of the best decisions I’ve made — I feel more energetic, more relaxed, and less fatigued. His plan is tailored and reviewed at every session. If anyone is dealing with mould exposure, I’d highly recommend him.

“

I’ve seen more progress in the last few months than I had in years through conventional medicine. At the start of the year I was in a really difficult place — I now have energy, motivation, and clarity again. Paul is personable and full of knowledge, and I felt genuinely listened to.

— Hannah · Chronic fatigue · Low energy

★★★★★

“

I’d been dealing with ongoing health issues that other practitioners hadn’t really got to the bottom of. Paul’s approach was much more thorough — the testing, the questionnaire, and the way he looked at the whole picture made a noticeable difference. My energy and general enthusiasm for life are a lot better after ten months working with him.

What We See Again and Again

The patterns that standard medicine misses.

Pattern 01

Gut + Fatigue + Thyroid

Gut dysfunction drives systemic inflammation that suppresses thyroid conversion — creating fatigue that responds to neither gut nor thyroid treatment alone.

Pattern 02

Post-Viral + Mitochondrial

A viral trigger depletes mitochondrial function and dysregulates the immune response. The virus resolves. The energy deficit doesn’t.

Pattern 03

Mould + Neurological Fatigue

Mycotoxin exposure triggers neuroinflammation and impairs detoxification pathways. Brain fog, exhaustion, and chemical sensitivity persist until the toxic load is addressed directly.

These aren’t rare presentations. They are the most common patterns in complex chronic fatigue — and they are almost always missed by standard investigation.

Frequently Asked

Questions about chronic fatigue

What causes chronic fatigue that doctors can't explain?

Chronic fatigue rarely has a single cause. It's typically driven by multiple overlapping systems under strain: gut dysfunction and dysbiosis, adrenal dysregulation (HPA-axis exhaustion), thyroid dysfunction that standard tests miss, mitochondrial energy production impairment, chronic low-grade inflammation, toxic load (including mycotoxins or heavy metals), and nutritional depletion. Standard testing doesn't investigate all of these simultaneously, which is why fatigue persists despite normal results.

Is ME/CFS the same as chronic fatigue?

ME/CFS and chronic fatigue syndrome are related but distinct. ME/CFS involves post-exertional malaise (significant symptom worsening after even minor physical or cognitive effort) and has specific diagnostic criteria. Chronic fatigue as described here is broader — it includes fatigue driven by the root causes above, which may or may not meet ME/CFS criteria. Many people with fatigue improve dramatically once the underlying dysfunction is addressed; ME/CFS recovery timelines are typically longer.

Can functional medicine help with fatigue?

Yes — when it focuses on root causes rather than symptom management. Functional medicine investigates why multiple systems have shifted out of optimal function simultaneously, rather than treating fatigue as a problem in itself. This approach looks at the interconnection between gut health, stress response, thyroid function, energy production, and toxic load — and addresses them in the correct sequence. This is what produces lasting change.

What tests are done for unexplained fatigue?

Functional testing goes far beyond standard pathology. A detailed case review is followed by selective testing including: comprehensive thyroid panel (TSH, fT3, fT4, rT3, antibodies), organic acids panel, adrenal cortisol mapping, mycotoxin screening, nutrient status assessment (B12, folate, iron, vitamin D, selenium), and gut microbiome analysis. Testing is chosen based on the clinical picture, not applied as a standard package.

How long does it take to recover from chronic fatigue?

Recovery timelines vary significantly based on severity, duration of illness, complexity of drivers, and individual response to intervention. Some people see meaningful improvement within 8-12 weeks. Others — particularly those with long-standing fatigue or multiple simultaneous drivers — require 6-12 months of consistent protocol adherence. Early intervention and correct sequencing of support accelerates outcomes considerably.

Do I need to come to the clinic in person?

No. All consultations are delivered online. This is designed for clients across the UK and Ireland who cannot access this level of investigation locally. Testing is arranged through functional medicine laboratories that ship sample kits directly to you, and follow-up consultations happen via secure video call.
