What Is CIRS? A Comprehensive Guide to Chronic Inflammatory Response Syndrome

By Alex Manos, MSc Nutrition | Functional Medicine Practitioner | Gut Health & Mycotoxin Specialist

Introduction: The Illness That Conventional Medicine Keeps Missing

You have seen doctor after doctor. You have been told your bloods are normal. You have been given a diagnoses of chronic fatigue syndrome, fibromyalgia, depression, or anxiety. You have been handed prescriptions that only partially help — or do nothing at all. And yet you know something is deeply, systemically wrong.

If this sounds familiar, you may be one of the millions of people living with an under-recognised, under-diagnosed, and deeply misunderstood condition called Chronic Inflammatory Response Syndrome — more commonly known as CIRS.

In over a decade of clinical practice, specialising in gut health, mycotoxins, and complex chronic illness, I have worked with countless patients who were years into their suffering before anyone connected the dots. CIRS is one of the most important areas of emerging medicine, and it is one I am deeply passionate about. This guide will walk you through everything you need to know — what CIRS is, what causes it, how it works in the body, how it is diagnosed, and crucially, what can be done about it.

If you are ready to move beyond surface-level answers and truly understand what may be driving your chronic illness, keep reading.

What Is CIRS? A Clear Definition

CIRS — Chronic Inflammatory Response Syndrome — is a complex, multi-system, multi-symptom illness driven by sustained activation of the innate immune system following exposure to biotoxins. The most common trigger is exposure to water-damaged buildings (WDBs) and the mould, mycotoxins, bacteria, and other inflammatory agents they harbour.

CIRS is a complex, multisystem illness driven by sustained innate immune activation following exposure to biotoxins such as mould, mycotoxins, Actinobacteria, and bacterial endotoxins in water-damaged buildings, as well as tick-borne and marine toxins.

In plain language: your immune system encounters a toxic trigger, mounts an inflammatory response, and then — critically — cannot stand down. The alarm stays switched on. And when your immune system is permanently in emergency mode, the downstream effects on virtually every organ system in your body are profound.

CIRS is an acquired medical condition characterised by innate immune dysregulation following respiratory exposure to water-damaged buildings. This chronic syndrome involves a range of symptoms that simultaneously affect multiple organ systems.

The term was first developed and researched by Dr Ritchie Shoemaker, a Maryland family physician who originally linked a chronic illness in his patients to biotoxins produced by the dinoflagellate Pfiesteria. His subsequent decades of research established the foundational science of CIRS as we understand it today.

Let's Define the Key Terms

Before going further, let me define some terms that will come up throughout this article:

Biotoxin: A poison produced by a living organism — in this context, primarily moulds, bacteria, and other microorganisms found in water-damaged environments.

Mycotoxin: A specific type of biotoxin produced by fungi (moulds). Mycotoxins are secondary metabolites produced by moulds. Over 400 mycotoxins have been identified, and there are likely many more. Moulds produce mycotoxins to allow them to compete in their environments for survival.

Innate immune system: This is your body's first line of defence — the rapid, non-specific immune response that activates immediately upon encountering a perceived threat. It is different from the adaptive immune system, which creates targeted antibodies.

Cytokines: Signalling proteins released by immune cells to coordinate an inflammatory response. In CIRS, these are chronically over-produced, leading to widespread inflammation.

Water-damaged building (WDB): Any structure that has experienced moisture intrusion — leaks, flooding, condensation, or inadequate ventilation — creating conditions in which mould, bacteria, and other inflammatory organisms can proliferate.

How Common Is CIRS?

The prevalence of CIRS is striking, yet it remains largely unrecognised in conventional medicine.

CIRS can affect up to 25% of the population, representing a silent epidemic. (source)

The WHO estimates that 10–50% of buildings have a moisture issue and that 15–40% of homes have mould problems.

Given that we spend the vast majority of our time indoors — at home, at work, in schools, in healthcare settings — the potential for widespread exposure is enormous. And yet CIRS is not taught in medical schools. It does not appear on standard diagnostic checklists. It is not part of the routine differential diagnosis (the list of possible conditions a clinician considers when evaluating symptoms). This is a fundamental problem.

Most patients with CIRS are misdiagnosed as having depression, anxiety, post-traumatic stress disorder, chronic fatigue syndrome, or fibromyalgia, among other illnesses.

Why Does CIRS Happen? The Genetic Connection

Here is a crucial piece of the puzzle: not everyone exposed to a water-damaged building becomes chronically ill. Some people feel unwell while in the building and recover once they leave. Others develop a debilitating, long-term illness. This difference comes down to genetics.

CIRS typically affects those with a genetic susceptibility, particularly HLA-DR/DQ gene variants. Roughly 24% of the population carries HLA haplotypes that make them susceptible to chronic inflammation from mould or Lyme exposure.

What is the HLA-DR gene? HLA stands for Human Leukocyte Antigen. These are proteins found on the surface of cells that help your immune system distinguish between your own cells and foreign invaders. The HLA-DR gene is particularly important in the adaptive immune system's ability to "recognise" biotoxins and tag them for elimination.

In those with susceptible HLA-DR variants, the adaptive immune system simply does not recognise the biotoxin as foreign. In biotoxin illness, due to specific genetic HLA susceptibilities, the adaptive immune system cannot see the biotoxins presented to it by the innate system and thus cannot produce antibodies to neutralise them. The toxin is not recognised as foreign.

Without this recognition, the toxin cannot be neutralised and eliminated in the normal way. Instead, it persists in the body — and the innate immune system keeps firing, over and over, in an attempt to deal with a threat it can never fully clear.

This also explains a pattern I see clinically time and time again: one family member becomes profoundly unwell in a damp home, while others living in the same building barely notice. The mould exposure is the same. The genetic response is different.

What Triggers CIRS?

While water-damaged buildings are by far the most common trigger, CIRS can be initiated by several biotoxin sources:

1. Water-damaged buildings and mould/mycotoxins This is the primary driver. Mycotoxins can cause inflammation and oxidative stress throughout the body, leading to a chronic disease often called Chronic Inflammatory Response Syndrome. Its symptoms overlap with those of many chronic diseases, such as Mast Cell Activation Syndrome, and chronic infections, such as Borrelia.

2. Tick-borne illness (Lyme disease) The bacteria Borrelia burgdorferi, which causes Lyme disease, produces biotoxins that can trigger the same CIRS cascade in genetically susceptible individuals.

3. Marine biotoxins Ciguatoxin (from contaminated fish) and other marine toxins have been shown to produce CIRS-like syndromes. Disruptions of innate and adaptive immune mechanisms were recorded at both the genomic and proteomic level. A disruption in the HLA–T cell receptor axis could indicate HLA haplotype sensitivity for this chronic syndrome, as noted in many autoimmune conditions. nih

4. MARCoNS MARCoNS stands for Multiple Antibiotic Resistant Coagulase Negative Staphylococci — a nasal biofilm infection commonly found in CIRS patients. MARCoNS colonises the deep nasal spaces and forms biofilms, releasing biotoxins that cleave MSH (melanocyte stimulating hormone), an anti-inflammatory neuropeptide. This creates a vicious cycle that perpetuates the CIRS inflammatory cascade even after initial exposure has been removed.

How Mycotoxins Damage Your Body: The Science

Understanding how mycotoxins cause harm is central to understanding CIRS. This is not simply an allergic reaction. This is a multi-pathway toxic and inflammatory assault on the body.

Inflammation and Oxidative Stress

Mechanisms of illness include inflammation, oxidative stress, toxicity, infection, allergy, and irritant effects of exposure.

Mycotoxins activate numerous inflammatory pathways simultaneously. They trigger the release of inflammatory cytokines (signalling proteins), activate the complement system (part of the innate immune response), and generate free radicals — unstable molecules that damage cells, proteins, and DNA.

Neurological Damage

One of the most alarming aspects of mycotoxin exposure is its direct effect on the brain and nervous system.

Human exposure to moulds, mycotoxins, and water-damaged buildings can cause neurological and neuropsychiatric signs and symptoms. Many of these clinical features can partly mimic or be similar to classic neurological disorders, including pain syndromes, movement disorders, delirium, dementia, and disorders of balance and coordination.

Damage to human neurological system cells resulting from exposure to mycotoxins confirms a previously controversial public health threat for occupants of water-damaged buildings. The constant activation of inflammatory and apoptotic pathways at low levels of exposure in human brain capillary endothelial cells, astrocytes, and neural progenitor cells may amplify damage to neurological tissues.

Mould enters the body through the nose via the olfactory neurons, which directly communicate with the brain. Mycotoxins induce toxicological effects similar to those associated with brain disorders, such as oxidative stress and inflammation.

This helps explain the severe cognitive symptoms — brain fog, memory impairment, word-finding difficulties, and mood disturbances — that are so characteristic of CIRS.

The Neuropsychiatric Impact

Exposure to mould and mycotoxins can affect the nervous system directly or through immune cell activation, contributing to neurodevelopmental and neuropsychiatric disorders. PubMed

Ochratoxin A is the most common mycotoxin found in foods and water-damaged buildings and has been associated with serious health problems, including severe neurological issues, in humans.

The Gut Connection

As a clinician whose practice is built around gut health, I want to highlight something often overlooked: the gut is intimately involved in CIRS. Mycotoxins disrupt the gut microbiome, damage the intestinal lining, and contribute to gut permeability (often called "leaky gut"). The gut-liver axis is also compromised — the liver secretes biotoxins into bile, which is released into the gut, but these tiny molecules are rapidly reabsorbed. The liver secretes the biotoxin into the bile, which is dumped into the gut; however, these biotoxins are very tiny and 95% of them are quickly reabsorbed. This is further compounded when the problem is mould toxicity from a water-damaged building and there is ongoing exposure.

This is one reason why supporting the gut and the bile system is such an important component of recovery and something we dive deep in to in our course Mould Mastery.

What Does CIRS Feel Like? A Look at the Symptoms

CIRS is sometimes called "the great imitator" — and for good reason. It produces a bewildering array of symptoms spanning virtually every system in the body. This is precisely why it is so frequently misdiagnosed.

CIRS provokes a range of symptoms that can be easily misdiagnosed as chronic fatigue syndrome, fibromyalgia, or even multiple sclerosis.

Here is a breakdown of the major symptom clusters, organised by body system:

Neurological and Cognitive:

  • Brain fog (difficulty thinking clearly, as if thinking through cotton wool)

  • Memory problems and concentration difficulties

  • Headaches

  • Dizziness and vertigo

  • Disorientation

  • Word-finding difficulties

  • Tingling and numbness

Fatigue:

  • Profound, debilitating exhaustion that is not relieved by rest

  • Post-exertional malaise (feeling significantly worse after physical or mental effort)

  • Weakness

Musculoskeletal:

  • Joint pain and stiffness

  • Muscle aches and cramps

  • Ice pick-like pains (sharp, stabbing pains in a specific location)

Respiratory:

  • Chronic sinus congestion

  • Shortness of breath

  • Persistent cough

  • Asthma-like symptoms

Gastrointestinal:

  • Nausea

  • Abdominal pain

  • Diarrhoea or constipation

  • Appetite changes

Hormonal and Metabolic:

  • Unexplained weight gain or inability to lose weight

  • Excessive thirst and frequent urination

  • Temperature dysregulation (inability to control body temperature)

  • Night sweats

Mood and Mental Health:

  • Depression and anxiety

  • Irritability

  • Emotional dysregulation

Other:

  • Skin rashes

  • Visual disturbances

  • Static shocks

  • Sensitivity to light and sound

  • Recurrent infections

The sheer breadth of this symptom picture is exactly why CIRS falls through the diagnostic cracks. Each specialist sees their piece of it. No one connects the dots. CIRS is simply not taught in medical school. It is not part of the standard differential diagnosis. And because the symptoms are so varied and so similar to other conditions, it falls through the cracks.

A particularly striking clinical observation: in a 2013 study of 112 patients with chronic fatigue syndrome, 104 (93%) tested positive for at least one mycotoxin. This suggests that mycotoxin-driven illness may be a significant, unrecognised driver of what is being labelled as chronic fatigue syndrome in many patients.

The Biochemistry of CIRS: What Is Actually Going Wrong?

For those who want to understand the deeper mechanisms, here is a clear explanation of what is happening inside the body.

The Innate Immune System Gets Stuck in “On"

Under normal circumstances, the innate immune system detects a threat, mounts a response, and then switches off once the threat is cleared. In CIRS, due to the HLA-DR genetic susceptibility, the biotoxins are never properly cleared. The innate immune system therefore never receives the signal to stand down.

The innate immune system continues to create inflammatory cytokines, leading to dysregulation of multiple systems and thus the CIRS diagnosis. Patients with CIRS have dysfunction of T regulatory cells, which are converted into pathogenic T lymphocytes via the inflammatory cytokine TGF-beta-1.

Key Biomarkers Disrupted in CIRS

Understanding the following biomarkers helps explain why CIRS affects so many systems simultaneously:

C4a — A split product of the complement system (part of the immune cascade). Elevated C4a is one of the most sensitive markers of immune activation in CIRS and correlates with symptom severity.

TGF-beta-1 (Transforming Growth Factor Beta-1) — A cytokine that, when chronically elevated, drives fibrosis (scarring), autoimmune activity, and airway reactivity. It also converts regulatory T cells (which keep inflammation in check) into inflammatory T cells.

MMP-9 (Matrix Metalloproteinase-9) — An enzyme that, when elevated, essentially opens up barriers in the body — including the blood-brain barrier — allowing inflammatory molecules to enter tissues they should not normally access. This is a key driver of neuroinflammation in CIRS.

MSH (Melanocyte Stimulating Hormone) — A critical neuroregulatory and anti-inflammatory hormone. MSH is a neuroregulatory hormone with powerful anti-inflammatory properties. Low MSH is found in the vast majority of CIRS patients and is responsible for many of the hormonal, sleep, and immune dysregulation features of the condition.

VEGF (Vascular Endothelial Growth Factor) — Regulates blood vessel growth and oxygen delivery to tissues. In CIRS, VEGF is often suppressed, leading to poor tissue oxygenation — which partly explains the profound fatigue and cognitive symptoms.

ADH (Anti-Diuretic Hormone) / Osmolality — ADH regulates water retention in the body, affecting hydration and electrolyte balance. Disruption here explains the excessive thirst and frequent urination many CIRS patients experience.

Leptin — Elevated levels of CIRS-related cytokines block hypothalamic receptors, creating leptin resistance. Leptin resistance decreases the body's ability to use fat stores as energy, which can lead to dramatic weight gain and inability to lose weight despite caloric restriction or regular physical exercise.

Brain Structure Changes

Perhaps the most sobering finding in CIRS research is that the inflammation can cause measurable structural changes in the brain. Advanced MRI analysis using a tool called NeuroQuant has shown specific patterns of brain volume changes in CIRS patients — including atrophy (shrinkage) of specific regions involved in memory and cognition. This is not "all in your head" in the dismissive sense — it is a demonstrable, measurable physical change.

How Is CIRS Diagnosed?

Diagnosing CIRS requires a thorough, multi-layered approach. Standard NHS or conventional blood tests will almost always come back normal — this is a hallmark feature of CIRS, and it is one of the main reasons it is so frequently missed.

For suspected mycotoxin illness, developing a list of indicators is important. Taking a thorough history of a person's potential mould exposure at their current home, past residences, and work location is critical. After clarifying the person's clinical symptoms and exposure history, the practitioner can perform tests to confirm specific mycotoxin exposure and then implement treatment plans. PubMed

The key diagnostic tools include:

1. Detailed Clinical History

This is always the starting point. A meticulous history exploring symptoms, their onset, their pattern, and crucially, any exposure to water-damaged environments is essential. Has anything changed since you moved house, changed workplace, or had a flood or leak?

2. Visual Contrast Sensitivity (VCS) Test

The Visual Contrast Sensitivity (VCS) test is among the most accessible instruments for detecting CIRS. It gauges sensitivity to minute changes in contrast, which nervous system inflammation can compromise. It is a simple, inexpensive online test that assesses neurological function and can act as a first-line screening tool.

3. HLA-DR Genetic Testing

This blood test determines whether you carry the genetic variants that predispose you to CIRS susceptibility. Knowing your HLA type provides crucial context for interpretation of the full clinical picture.

4. CIRS Biomarker Panel

A specialist blood panel assessing the specific immune and hormonal markers disrupted in CIRS — including C4a, TGF-beta-1, MMP-9, MSH, VEGF, C3a, VIP, ACTH/cortisol, and ADH/osmolality.

Often raised in those with CIRS, some of the most crucial tests include indicators of inflammation, including C4a and TGF-β1. Tests evaluating the function of the hypothalamic-pituitary-adrenal (HPA) axis, such as ACTH and cortisol levels, can reveal disturbances resulting from chronic inflammation. AIHCP

5. MARCoNS Nasal Swab

A deep nasal swab sent to a specialist laboratory to detect the presence of the antibiotic-resistant biofilm bacteria that commonly colonise the sinuses of CIRS patients.

6. Mycotoxin Urine Testing

Urine testing for specific mycotoxins (including ochratoxin A, trichothecenes, and aflatoxins) can confirm ongoing toxic load.

7. Environmental Testing

Testing your home and workplace for mould and mycotoxins is a critical part of the diagnostic puzzle. Tests such as ERMI (Environmental Relative Mouldiness Index) and HERTSMI-2 can quantify the mould burden in a building.

8. NeuroQuant MRI

In cases with significant cognitive symptoms, a NeuroQuant MRI — a specialised software-enhanced brain scan that measures volumes of specific brain structures — can reveal the characteristic patterns of neuroinflammation seen in CIRS.

A key point to emphasise: a negative mould allergy test does not rule out CIRS. Mould allergy and CIRS are completely different processes involving different arms of the immune system. It is entirely possible — and in fact common — to have a negative mould allergy test and still have CIRS.

The CIRS–Gut Connection: Why Gut Health Is Central to Recovery

As a practitioner specialising in gut health, I want to spend a moment on the profound relationship between CIRS and the gut — because this is an area that is often overlooked even in the CIRS-specialist community.

The gut is not simply a passive bystander in CIRS. It is a critical battleground. Mycotoxins damage the gut lining, disrupt the integrity of the intestinal barrier, alter the composition of the gut microbiome, and interfere with bile flow and detoxification pathways.

Exposure to mould and mould components is well known to trigger inflammation, oxidative stress, and inflammatory reactions in both human and animal studies.

The enterohepatic circulation — the cycle by which the liver releases bile (and the biotoxins bound to it) into the gut, and the gut then reabsorbs it — becomes a critical target in treatment. Without intervention, biotoxins keep cycling around this loop, perpetuating the inflammatory response.

The gut microbiome also plays a role in detoxification capacity, immune regulation, and the production of neurotransmitters that influence mood and cognition. Restoring gut health is therefore not a peripheral concern in CIRS — it is foundational.

How Is CIRS Treated?

The Shoemaker Protocol is the most well-studied, sequentially structured treatment framework for CIRS.

The only treatment with documented clinical efficacy was the Shoemaker Protocol, which was described in 11 of 13 reviewed articles. This treatment protocol exhibits superior outcomes compared with the treatment protocols for ME/CFS. PubMed

The protocol is a 12-step framework. Each step must be completed in order, as each builds on the last. Here is an overview of the core principles:

Step 1: Remove from Exposure This is non-negotiable and the most critical first step. No treatment will work if ongoing exposure continues. The building environment must be assessed and either remediated or abandoned.

Step 2: Biotoxin Binders Cholestyramine (CSM), a prescription bile acid sequestrant, binds biotoxins in the gut for safe removal. Shoemaker's research shows that CSM improves visual contrast sensitivity scores and reduces symptom clusters in CIRS patients. Fatigue to Flourish Natural binders such as okra and beet extract can also be used.

Step 3: Treat MARCoNS Up to 80% of CIRS patients have MARCoNS colonising their sinuses. This bacterium produces exotoxins that perpetuate inflammation and further lower MSH levels. Treatment typically involves a compounded BEG nasal spray (Bactroban, EDTA, Gentamicin).

Steps 4–11: Correcting the Hormonal and Immune Cascade This involves sequentially addressing and normalising the various disrupted biomarkers — anti-gliadin antibodies, androgen levels, ADH/osmolality, MMP-9, VEGF, C3a, C4a, and TGF-beta-1.

Step 12: Vasoactive Intestinal Peptide (VIP) VIP is a neuropeptide with powerful anti-inflammatory and regulatory effects. Intranasal VIP, administered in the final stage of the protocol (only once the patient has passed VCS testing and confirmed a safe, mould-free environment), can help restore normal function across multiple systems.

Beyond the Shoemaker Protocol, a comprehensive integrative approach to CIRS recovery will also include:

  • Nutritional support targeting inflammation and oxidative stress

  • Gut restoration protocols

  • Glutathione and antioxidant support

  • Liver and bile support

  • Nervous system regulation (breathwork, HRV training, mind-body practices)

  • Detoxification support through movement, sauna, and lymphatic drainage

Why Is CIRS So Frequently Missed?

This is a question I am asked constantly — and it deserves a direct, honest answer.

CIRS is missed for several interconnected reasons:

1. It is not taught in medical school. Conventional medical training does not include CIRS. GPs and hospital consultants are simply not equipped to recognise it.

2. Standard tests appear normal. Routine blood tests — full blood count, inflammatory markers like CRP and ESR, thyroid function — are almost always normal in CIRS. This leads clinicians to conclude nothing is wrong.

3. Symptoms are diffuse and overlap with other conditions. CIRS is frequently misdiagnosed as fibromyalgia, lupus, Lyme disease, multiple sclerosis, Parkinson's disease, menopause, andropause, chronic fatigue syndrome, chronic pain syndrome, depression, post-traumatic stress disorder, and even allergies.

4. Specialist siloing. Patients see a rheumatologist for joint pain, a neurologist for cognitive symptoms, a gastroenterologist for gut symptoms, and a psychiatrist for depression. Each specialist treats their piece of the puzzle. No one ever looks at the whole person.

5. The mould connection is dismissed. There remains a significant degree of scepticism in conventional medicine about mould as a cause of systemic illness beyond allergy and asthma. This cultural bias in the medical establishment perpetuates diagnostic delays.

The result is years — sometimes decades — of suffering, misdiagnosis, and treatments that do not address the root cause.

CIRS and the Gut–Brain Axis: The Neuropsychiatric Dimension

One dimension of CIRS that I find particularly compelling from a clinical perspective is its neuropsychiatric impact — the way in which a toxic environmental exposure can fundamentally alter mood, cognition, and mental health.

People exposed to moulds and mycotoxins present with symptoms affecting multiple organs, including the lungs, musculoskeletal system, as well as the central and peripheral nervous systems.

The mechanisms are multiple: direct neurotoxicity from mycotoxins, neuroinflammation via elevated MMP-9 allowing inflammatory molecules across the blood-brain barrier, disruption of MSH (which regulates mood and sleep), and secondary effects of chronic pain and fatigue on mental wellbeing.

There is also compelling research linking mycotoxin exposure to inhalational Alzheimer's disease — a concept introduced by Dr Dale Bredesen, suggesting that chronic neuroinflammation from environmental exposures including mould may be a significant driver of dementia pathology in a subset of patients.

The gut–brain axis is also implicated here. Mycotoxin-driven gut dysbiosis (imbalance in the gut microbiome), intestinal permeability, and disrupted neurotransmitter production all feed back into the neurological and psychiatric symptoms of CIRS. This is a central focus of my clinical work and a key thread running through my Mould Mastery programme.

Could You Have CIRS? Key Questions to Ask Yourself

Consider the following questions honestly:

  1. Have your symptoms developed or significantly worsened after moving to a new home, changing workplace, or following a period of flooding, water damage, or damp?

  2. Have you had extensive investigation with multiple "normal" results?

  3. Have you been given diagnoses of chronic fatigue, fibromyalgia, depression, anxiety, IBS, or "medically unexplained symptoms"?

  4. Do you feel worse in certain buildings and better when you are away (on holiday, for example)?

  5. Does only one member of your household seem to be significantly unwell, while others are largely fine?

  6. Have you noticed mould, a musty smell, or a history of damp in your home or workplace?

  7. Do you have multiple seemingly unrelated symptoms affecting different body systems simultaneously?

If you are nodding along to several of these questions, CIRS deserves to be on your radar.

What Is Mould Mastery — And How Can It Help You?

If reading this article has resonated with you — if you recognise yourself in the symptom picture, if you suspect your environment may be making you sick, or if you have been failed by conventional medicine — we want to tell you about Mould Mastery.

Mould Mastery is the structured, comprehensive programme we have have developed from years of clinical experience working with complex mycotoxin-related illness. It is designed to give you everything you need to understand what has happened to your body, how to properly investigate it, and how to begin a systematic, evidence-based path to recovery.

Inside Mould Mastery, you will learn:

  • The science behind mycotoxins and CIRS — explained clearly, without jargon, so you actually understand what is happening in your body.

  • How to identify and test for mould in your environment — including which tests to use and how to interpret them.

  • The full diagnostic pathway — from VCS testing to biomarker panels to genetic testing, you will know exactly what to ask for and why.

  • A recovery framework — including nutritional, gut health, detoxification, and lifestyle strategies that we use with our 1-2-1 clients.

  • The gut–mould connection — how mycotoxins affect the microbiome and gut integrity, and what to do about it.

  • The neuropsychiatric dimension — understanding and addressing brain fog, mood disruption, and cognitive impairment.

  • Practical tools and resources — so you can take informed, purposeful action, rather than feeling overwhelmed and lost.

This is not a quick-fix programme. CIRS is a complex, layered condition and recovery takes time, precision, and patience. But with the right framework — the same framework we use in our private practices — recovery is absolutely achievable.

I have seen patients who were bedridden, misdiagnosed, and dismissed regain their health, their clarity, and their lives. That transformation is what this work is about.

The Bottom Line

CIRS — Chronic Inflammatory Response Syndrome — is a real, measurable, biologically complex condition that affects a significant proportion of the population. It is driven by exposure to biotoxins, most commonly from water-damaged buildings, in individuals with a specific genetic susceptibility. It produces a wide-ranging, multi-system symptom picture that routinely evades conventional diagnosis. And it has an evidence-based treatment pathway that, when followed correctly, can lead to genuine, lasting recovery.

The CIRS Protocol is a sequential 12-step therapeutic framework designed to diagnose and resolve CIRS through a combination of environmental, pharmacological, and biochemical interventions.
