What Is CIRS — And Why Your Home May Be the Cause
What Is CIRS — And Why Your Home
May Be the Cause
Chronic Inflammatory Response Syndrome is one of the most under diagnosed conditions in America. Thousands of patients are suffering without answers. Here's what you need to know — and how your environment may hold the key.
You've Seen the Doctors. Taken the Tests. Nothing Adds Up.
Fatigue that sleep doesn't fix. Brain fog so thick you can't finish a sentence. Joint pain, headaches, sensitivity to light, digestive problems — symptoms that shift, stack, and seem totally unrelated. If that sounds familiar, you're not imagining it.
For many people, what's actually happening is Chronic Inflammatory Response Syndrome (CIRS): a condition triggered by biotoxin exposure that sends the immune system into a state of prolonged, dysregulated inflammation. And in a significant number of cases, the source of that exposure is inside the home.
"I saw seven different specialists over two years. None of them connected it to my house. Once we found the mold and I moved out, my symptoms started clearing within weeks." — A common story among CIRS patients in Utah and across the country.
So What Exactly Is CIRS?
CIRS stands for Chronic Inflammatory Response Syndrome. It was first described and systematically studied by Dr. Ritchie Shoemaker, a physician who spent decades researching how certain toxins produced by living organisms — called biotoxins — affect the human body.
Unlike a typical infection or allergy, CIRS isn't about the body being overwhelmed by a pathogen. It's about a failure in the body's ability to clear biotoxins once they enter the system. In roughly 25% of the population, a specific genetic variation (HLA-DR) means the immune system can't properly "tag" and remove these toxins. They recirculate, triggering ongoing inflammation that damages multiple body systems simultaneously.
What Causes CIRS?
The most common biotoxin trigger is water-damaged buildings — homes, offices, and schools where moisture has allowed mold, bacteria, and other microorganisms to grow. But CIRS can also be triggered by:
Mold and mycotoxins from water-damaged structures
Actinomycetes (bacteria that thrive in wet building materials)
Volatile Organic Compounds (VOCs) released by building materials
Lyme disease and related tick-borne co-infections
Ciguatera fish poisoning
Harmful algal blooms (blue-green algae)
Of these, water-damaged buildings are by far the most prevalent source in everyday life — and the one most likely to go undetected for years.
Why Is CIRS So Frequently Missed?
1. The Symptoms Mimic Dozens of Other Conditions
CIRS can present as chronic fatigue syndrome, fibromyalgia, depression, anxiety, ADHD, autoimmune disease, or even psychiatric illness. Without a doctor who specifically screens for it, patients are often diagnosed with — and treated for — the wrong condition entirely.
2. Standard Lab Work Looks Normal
Routine bloodwork rarely flags CIRS. The biomarkers that reveal it — MMP-9, TGF-beta-1, VEGF, VIP, MSH, and others — are not part of standard panels. Patients are told they're "fine" while their quality of life deteriorates.
3. Patients Leave the Source Daily and Return Nightly
Many CIRS patients feel better when they're away from home — on vacation, traveling for work, staying with family — but assume it's just stress relief. They go back home, and the cycle continues. The connection between the environment and the symptoms is rarely made.
4. Mold Is Often Hidden
In Utah's climate, moisture intrusion frequently occurs inside wall cavities, under flooring, inside HVAC systems, or in crawl spaces — completely invisible from the surface. A visual inspection of a home can look totally clean while mold colonization is extensive behind the scenes.
This is why environmental investigation — not just symptom management — is often the critical missing piece in CIRS recovery.
How Does Biotoxin Exposure Actually Make You Sick?
When a genetically susceptible person is exposed to biotoxins from a water-damaged building, the following chain of events unfolds:
Biotoxins enter the body through inhalation, ingestion, or skin contact
The immune system fails to recognize and tag them for removal
Toxins bind to receptors throughout the body, triggering widespread inflammation
Inflammatory pathways become self-perpetuating — the body stays in an alarm state even without new exposure
Over time, multiple hormonal, neurological, and immune systems become dysregulated
The result is a cascade of symptoms across virtually every organ system. CIRS patients often have issues with cognition, sleep, hormones, cardiovascular function, and gastrointestinal health — all simultaneously. Because no single specialist "owns" all of these systems, patients fall through the cracks of conventional care.
CIRS and Utah: Why This Matters Here
Utah's climate creates specific conditions that put homeowners and renters at risk. Despite the reputation for dry air, the Wasatch Front — including Salt Lake City, West Valley, and surrounding communities — sees consistent moisture intrusion issues from:
Rapid freeze-thaw cycles that stress building envelopes
Basement moisture from high water table and clay soils
Evaporative coolers (swamp coolers) that introduce moisture directly into duct systems
Aging housing stock with inadequate vapor barriers and waterproofing
Flash flooding and snowmelt events causing acute water intrusion
Many Utah homes that appear perfectly normal have significant hidden mold colonization — particularly in basements, crawl spaces, attics, and around windows. If you or a family member has been experiencing unexplained chronic symptoms, the air quality inside your home deserves serious scrutiny.
What a Proper Environmental Investigation Involves
A thorough environmental assessment goes well beyond a basic mold test. Comprehensive investigation typically includes:
ERMI or HERTSMI-2 Testing
The Environmental Relative Moldiness Index (ERMI) uses DNA analysis of a settled dust sample to identify and quantify mold species present in the home. HERTSMI-2 is a more focused version specifically correlated with CIRS risk. Both provide objective, quantifiable data rather than a visual guess.
Air Sampling and Spore Counts
Air sampling captures what is actively airborne in the living environment — what you're actually breathing. Results are compared against outdoor baseline levels to determine if the indoor environment is elevated.
Moisture Mapping
Using thermal imaging and moisture meters, investigators can identify areas of hidden moisture intrusion inside walls, ceilings, and flooring — often before visible mold growth has occurred.
HVAC and Ductwork Evaluation
The HVAC system is a frequent reservoir and distribution channel for mold and bacteria. A proper investigation examines the air handler, ductwork, coils, and drain pans.
Visual and Structural Inspection
Identifying the source of moisture — whether a roof leak, plumbing failure, foundation issue, or condensation problem — is essential. Treating the biological contamination without addressing the moisture source guarantees recurrence.
A CIRS-informed environmental investigation isn't just looking for mold. It's identifying whether your home meets the criteria that correlate with human illness — and providing the documentation needed to guide remediation and medical treatment.
If You Suspect CIRS: Where to Start
On the Medical Side
Seek a physician trained in the Shoemaker Protocol or biotoxin illness
Request a visual contrast sensitivity (VCS) test — a free, validated screening tool for neurotoxin exposure
Ask about CIRS-specific lab panels if your doctor is open to it
Consult resources at survivingmold.com for provider directories and patient education
On the Environmental Side
Begin with an ERMI or HERTSMI-2 test — affordable and non-invasive
Have a qualified inspector assess your home for moisture sources and hidden mold
If you rent, document everything and know your rights regarding habitability
Consider your workplace and other environments where you spend significant time
Recovery from CIRS is absolutely possible — but it requires removing the source of exposure. No amount of medication or supplementation will resolve CIRS if the person remains in a biotoxin-rich environment. Environmental remediation is medicine.
Your home should be the place you heal —
not the place that's making you sick.
If you're in Utah and concerned about biotoxin exposure in your home or building, a professional environmental assessment is the most important first step you can take. We specialize in CIRS-informed investigations designed to give you — and your doctor — the answers you need.
