While much of the attention surrounding The Secret Lives of Mormon Wives has focused on controversy involving Taylor Frankie Paul and the cancellation of the Bachelorette season, there is another, quieter story unfolding behind the scenes, one that is specifically focused around health.

Mikayla Matthews’ health journey highlights something far more important and far more common than most people realize: living with a complex, often invisible illness.1

Mikayla Matthews, a cast member on the show, has been open about her ongoing battle with complex chronic health conditions. Matthews confirmed on her Instagram Stories in March 2026 that she is suffering from Chronic Inflammatory Response Syndrome (CIRS), a condition brought on by prolonged exposure to toxins, specifically mold. 

She has also been candid about the severity of her condition, writing:

“I’m genuinely just barely surviving… Chronic illness is all consuming…”2

As a Licensed Integrative Medicine Practitioner specializing in multi-system chronic conditions, and having followed her health journey, I would strongly encourage her to also explore Mast Cell Activation Syndrome (MCAS), a condition that often goes hand in hand with CIRS and mold illness.

For many viewers, this may be the first time hearing about CIRS or becoming severely ill from toxic mold exposure. But for those living with it, the condition can be life-altering.

Her story opens the door to a deeper conversation about conditions like MCAS, mold illness, and CIRS.  Conditions that are often misunderstood, underdiagnosed, and deeply impactful.

Who Is Mikayla Matthews?

Mikayla Matthews is a reality television personality featured on The Secret Lives of Mormon Wives, a show that has drawn significant public attention for its portrayal of relationships, identity, and modern family dynamics.

While much of the spotlight has focused on the show’s social dynamics, Mikayla has also shared aspects of her personal health journey, bringing visibility to the challenges of navigating chronic illness while living in the public eye.

Her openness offers a rare glimpse into what many individuals experience privately: a body that feels unpredictable, reactive, and difficult to stabilize.

Mikayla has also helped bring increased awareness to mold illness and CIRS, conditions that are frequently overlooked or misunderstood.

What Is CIRS and How Is It Connected to Toxic Mold Exposure?

Chronic Inflammatory Response Syndrome (CIRS) is a multi-system inflammatory condition triggered by exposure to biotoxins, most commonly from mold in water-damaged buildings.

Mikayla herself described the root of her condition as being “brought on [by] prolonged exposures to toxins (mold)”2

When mold grows in indoor environments, it releases microscopic toxins called mycotoxins, which can trigger a chronic immune response in susceptible individuals.

Research has shown that approximately 25–30% of the population carries specific HLA-DR genetic haplotypes, which impair the body’s ability to recognize and eliminate biotoxins effectively. These individuals are more vulnerable to developing conditions like CIRS.

This becomes especially concerning when considering how common mold exposure is.

According to Environmental Working Group (EWG)-referenced data:

  • More than 50% of homes in the United States have some form of water damage, creating an environment where mold can grow and persist. 

This makes mold-related illness a largely hidden and widespread environmental health issue.

CIRS can affect multiple systems in the body, which aligns with what Mikayla has shared about her experience. She noted that her illness has impacted: “nerves, skin, hair, brain, gut, liver, hormones”2

How Is MCAS Related to CIRS and Mold Exposure?

Mast Cell Activation Syndrome (MCAS) is a condition in which mast cells become overactive, releasing excessive inflammatory chemicals in response to triggers.

Symptoms can include:

  • Skin reactions (rashes, hives, flushing)
  • Food sensitivities
  • Neurological symptoms
  • Gastrointestinal distress

Mikayla’s visible skin flares and sensitivity align with symptoms commonly seen in MCAS. In fact, she has spoken openly about how her skin has impacted her daily life, sharing that: “I had like a year and a half where I couldn’t look people in the eyes…”2  

This level of skin reactivity is very common in mast cell involvement.

When the body is in a chronic inflammatory state due to mold exposure and CIRS:

  • Mast cells become hypersensitive
  • The immune system becomes overreactive
  • Symptoms escalate across multiple systems

Living with Mold Illness, CIRS, and MCAS in the Public Eye

Managing multi-system chronic conditions is challenging in private life, doing so while being part of a reality television show adds another layer of difficulty.

Mikayla has shared how deeply her illness has impacted her daily life and identity, including her role as a mother: “I haven’t been able to show up as the mom I want to be…”2 

She has also described the emotional toll of living with chronic illness, including guilt, isolation, and missing out on opportunities due to her health.

Chronic illness does not follow a predictable schedule. Symptoms can flare unexpectedly, making daily routines, and filming commitments more difficult to maintain.

While viewers may focus on the visible drama of a show, behind the scenes, individuals like Mikayla are often navigating complex and exhausting health challenges.

Why Awareness Matters

Awareness around mold illness, CIRS, and MCAS is critical.

Many individuals spend years:

  • Being misdiagnosed
  • Having symptoms dismissed
  • Treating symptoms without addressing root causes

Without recognizing underlying drivers like mold exposure, treatment often remains incomplete.

Stories like Mikayla’s help bring these conversations into the mainstream, where they are long overdue.

For many people, this may be the first time recognizing that their own symptoms could be connected to environmental exposure and immune dysregulation.

A Broader Perspective on Root Causes

While mold illness plays a significant role in conditions like CIRS and MCAS, it is often part of a broader web of contributing factors, including:

These factors interact and compound, creating a state of chronic inflammation and sensitivity.

Understanding this interconnectedness is key to moving beyond symptom management and toward addressing root causes.

Mikayla Matthews’ experience highlights something far more universal than reality television.

Conditions like mold illness, CIRS, and MCAS are not rare, they are simply under-recognized.

As awareness grows, stories like hers have the potential to shift the conversation, helping more people connect the dots between their symptoms, environmental exposures, and the deeper drivers of chronic illness and how to approach healing all together.
