I have worked clinically with mould-related illness and Chronic Inflammatory Response Syndrome (CIRS) for more than a decade, predominantly within integrative medicine and collaborative-care settings. During this time, my approach has evolved considerably and is informed by a range of clinical frameworks, environmental medicine principles, current research and, importantly, the experience gained from working with people affected by damp and water-damaged buildings over many years.

Health effects associated with mould and water-damaged buildings exist across a spectrum. Some people primarily experience respiratory, sinus or allergic symptoms, while others develop more complex presentations involving fatigue, cognitive difficulties, gastrointestinal symptoms, immune and inflammatory dysfunction, histamine or mast-cell related symptoms, sleep disturbance and other multisystem complaints.

CIRS is one framework used to describe a particular multisystem inflammatory presentation associated with exposure to water-damaged buildings and other environmental biotoxins. However, not everyone affected by a mouldy or water-damaged environment has CIRS, and mould-related illness should not be considered a single diagnosis with a single treatment protocol.

Health Effects of Damp & Water-Damaged Buildings

Water damage and persistent dampness can create an indoor environment containing moulds, fungal fragments, bacteria and other microbial and chemical contaminants. The health effects of these environments can vary considerably between individuals according to the nature and duration of exposure, underlying health, allergic or immune susceptibility and other contributing factors.

Presentations may include:

• Chronic or recurrent sinus and respiratory symptoms

• Allergic rhinitis and mould sensitisation

• Asthma or worsening of existing respiratory conditions

• Fatigue and reduced exercise tolerance

• Cognitive difficulties or “brain fog”

• Headaches

• Sleep disturbance

• Gastrointestinal symptoms

• Skin symptoms

• Histamine intolerance or mast-cell related symptoms

• Persistent inflammatory or immune symptoms

• Increased sensitivity to environmental exposures

• Complex multisystem illness

Symptoms such as fatigue, cognitive dysfunction and gastrointestinal disturbance are not specific to mould exposure and may occur in many other conditions. A thorough clinical assessment is therefore important rather than attributing a complex presentation to mould exposure on symptoms alone.

Chronic Inflammatory Response Syndrome (CIRS)

Chronic Inflammatory Response Syndrome (CIRS) is a clinical framework that has been developed to describe a subset of people who experience persistent multisystem symptoms following exposure to water-damaged buildings and other biotoxins.

My approach to CIRS has been informed by established CIRS models and practitioner training, but is not based exclusively on a single protocol. Assessment and treatment are individualised and incorporate broader environmental medicine, nutritional, gastrointestinal, immune and integrative healthcare considerations where relevant.

CIRS may be considered as one possible presentation within the broader spectrum of mould and water-damaged building-related illness. Other recognised conditions associated with damp or mould exposure, including allergic and respiratory disease, also need to be considered, as do unrelated medical conditions that may produce similar symptoms.

My Approach to Mould-Related Illness

After more than a decade working with these presentations, I have found that mould-related illness is rarely best approached through a rigid treatment protocol. Two people exposed to the same building may experience very different health effects and may require quite different clinical approaches.

Assessment begins with a comprehensive review of the health history, symptom development and potential environmental exposures. Where appropriate, consideration may be given to:

• Exposure history — including current and previous homes, workplaces and other potentially water-damaged environments

• Environmental assessment — identifying moisture, water damage, mould growth and other factors that may indicate an unhealthy indoor environment

• Respiratory and allergic health — including sinus symptoms, asthma, mould sensitisation and other respiratory presentations

• Immune and inflammatory function — considering the broader clinical and pathological picture rather than relying on a single biomarker

• Mast-cell and histamine-related symptoms — where these form part of the clinical presentation

• Gut and microbiome health — including gastrointestinal symptoms, intestinal function and relevant microbiome disturbances

• Nutrition and metabolic health — identifying deficiencies, dietary factors and broader metabolic issues that may influence recovery

• Infections and other co-existing conditions — investigating other potential contributors where clinically indicated

• Nervous system, sleep and stress physiology — particularly where chronic illness has resulted in significant sleep disturbance, autonomic symptoms or reduced resilience

Treatment is then individualised according to the factors identified rather than assuming that every person exposed to mould requires the same sequence of interventions.

Assessing the Environment

Addressing a significant ongoing environmental exposure is an important part of managing mould-related illness. Treatment directed solely at the individual may have limited benefit if they continue to spend substantial time in an environment with unresolved moisture or microbial contamination.

Assessment of a building may involve consideration of:

• Current or previous water damage

• Roof, plumbing or building-envelope leaks

• Visible mould or mould odour

• Indoor humidity and condensation

• Moisture within building materials

• Heating and ventilation

• Previous remediation

• Environmental sampling or testing where appropriate

• Professional building or indoor environmental assessment where required

I have undertaken additional training in mould and water-damaged building assessment and am certified as a Mould Testing Technician through the Australian College of Environmental Studies. This allows environmental information to be considered alongside the clinical presentation and can help determine when further investigation by appropriately qualified building, environmental or remediation professionals is warranted.

Testing & Investigation

There is no single laboratory or environmental test that can diagnose every form of mould-related illness. Investigation should therefore be selected according to the individual's symptoms, exposure history and clinical presentation.

Depending on the circumstances, this may include conventional pathology, allergy or fungal sensitisation testing, respiratory investigations, selected immune and inflammatory markers, nutritional assessment, gastrointestinal or microbiome investigations, and other testing relevant to the differential diagnosis.

CIRS-related investigations may also be considered where clinically appropriate. Rather than automatically applying a fixed panel of biomarkers to every patient, testing is used selectively where the result is likely to contribute meaningfully to assessment or management.

Environmental assessment is considered separately from medical diagnosis. Building inspection, moisture assessment and environmental testing can provide useful information about the condition of a building, but results need to be interpreted within their limitations and alongside the broader exposure history.

Treatment

Treatment depends on the nature of the presentation and may change over time. An individual programme may incorporate:

• Identification and reduction of significant ongoing environmental exposure

• Individualised nutrition and food-as-medicine strategies

• Nutritional medicine

• Herbal medicine

• Gastrointestinal and microbiome support

• Support for allergic, immune, inflammatory or histamine-related presentations

• Correction of relevant nutritional deficiencies

• Sleep and lifestyle interventions

• Carefully selected binding or gastrointestinal strategies where clinically appropriate

• Management of co-existing health conditions

• Referral to medical, respiratory, allergy, environmental or other healthcare professionals where required

The aim is not simply to “treat mould”, but to understand how environmental exposure relates to the individual's broader clinical picture and develop an appropriate, staged approach to recovery.

An Integrative & Collaborative Approach

Mould-related illness can overlap with respiratory disease, allergy, ME/CFS, post-infectious illness, MCAS, gastrointestinal disorders, autoimmune conditions and other complex chronic presentations. It is therefore important not to assume that every symptom is attributable to mould or CIRS.

My approach integrates more than a decade of clinical experience in mould-related illness with environmental assessment, naturopathic medicine and collaborative healthcare. Where appropriate, I work alongside GPs, integrative doctors, medical specialists, allied health practitioners and building or environmental professionals to develop a broader understanding of both the individual's health and their environment.
