She Got So Sick, She Forgot Where She Lived

When the Tests Say You’re Fine, But You Know You’re Not

Diane describes reaching a point where she wondered whether she was dying.

Yet the testing she was receiving wasn’t providing an explanation.

At the time, she was also in medical school. Stress, lack of sleep, and the demands of her education seemed like reasonable explanations for why she felt so terrible.

But then she graduated.

Her classmates began recovering from the grueling pace of school.

Diane didn’t.

She continued getting worse.

Eventually, with her medical education behind her, she began investigating possibilities that hadn’t previously been explored. Her search led her to Lyme disease and mold illness, which became important pieces of understanding her own health.

That experience also gave her a different way of thinking about what a “normal” result actually means.

Testing is incredibly valuable, but every test has boundaries. It can only measure what it was designed to measure, using the method and reference criteria established for that test.

So when symptoms persist, a normal result may answer one question without necessarily answering every question.

As Diane says near the end of the episode:

“The body doesn’t lie.”

Chronic Illness May Be a Puzzle, Not a Single Root Cause

“Root cause” has become one of the most familiar phrases in functional and integrative health.

Diane would make one important edit:

Root causes. Plural.

She describes chronic illness as a puzzle made up of many pieces.

For one person, an infection may be part of that puzzle. Environmental exposures may be another. Gut health, hormones, cellular function, immune health, stress, or other factors may contribute additional pieces.

That distinction matters because finding and addressing one legitimate contributor doesn’t guarantee that every symptom will disappear.

It also doesn’t necessarily mean that contributor was irrelevant.

You may simply have another piece of the puzzle left to find.

This is where Diane believes chronic illness requires curiosity. Instead of forcing every symptom underneath one explanation, the goal becomes understanding how multiple factors may be interacting within one person.

Where Does Your Environment Fit Into the Picture?

Michael asks Diane directly how much she believes environmental factors can contribute to chronic illness.

Her answer is immediate:

“Huge. Huge.”

But she doesn’t argue that every chronic condition is caused by mold, or even by the environment alone.

Instead, environmental exposures are another category she believes deserves consideration when the circumstances warrant it.

Mold is one example discussed extensively throughout the episode, but Diane also talks about toxic metals, pesticides, herbicides, and other exposures that can become part of a person’s overall health picture.

It raises an important question for anyone investigating persistent symptoms:

Are we looking only at the body, or are we also considering the environment that body spends its time in?

Our health doesn’t exist separately from our surroundings. We breathe the air inside our homes. We interact with dust. We encounter building materials, consumer products, water, food, workplaces, and countless other environmental inputs every day.

That doesn’t mean your home is automatically responsible when you don’t feel well.

It means the environment can be one more piece worth investigating rather than automatically excluding.

Why Mold Testing Is More Complicated Than “Positive” or “Negative”

One of the most useful parts of the conversation is Michael and Diane’s discussion about testing.

There isn’t one mold test that answers every possible question.

Testing the body and testing a building are also fundamentally different investigations.

On the health side, Diane discusses several methods she uses or encounters in her work, including inflammatory markers, antibody testing, and urinary mycotoxin testing. Each can provide different information, and each comes with limitations that have to be understood when interpreting the results.

The same principle applies to the home.

Michael and Diane discuss air sampling as well as dust and surface-based environmental testing. Air samples provide information about what was captured in the air at a particular place and time, while settled dust can offer another window into what has accumulated within the indoor environment.

That is also where The Dust Test enters the conversation.

Diane discusses her experience using environmental dust testing and the value of comparing environmental findings with the larger clinical picture.

The takeaway isn’t that one testing method is magical.

It’s that good investigation requires understanding what your test can tell you, what it can’t tell you, and what additional questions may still need to be asked.

What Happens When the Exposure Is No Longer Just About the House?

The conversation then moves into one of its most fascinating topics: fungal colonization.

Diane explains that, in some patients, she considers whether fungal organisms may colonize areas of the body such as the sinuses or lungs following exposure.

She describes the concept with a striking phrase:

“We quote unquote become the house.”

The idea adds another layer to why mold-related health concerns can become complicated.

Someone’s current home may not necessarily represent their entire exposure history. They may have lived or worked somewhere else previously. They may have moved. The original moisture or mold problem may have been corrected.

For patients with persistent symptoms, Diane’s broader point is that investigating only the present environment may not always tell the entire story.

And, as with the other health topics discussed in this episode, these questions belong in conversations with qualified healthcare professionals who can evaluate an individual’s symptoms, history, testing, and other potential contributors.

When One Person Is Sick and Their Partner Feels Fine

Environmental illness can create another confusing situation.

Two people share the same home.

One is experiencing significant symptoms.

The other feels completely fine.

It’s easy for that difference to become evidence against the environment being involved at all.

But people aren’t biologically identical.

Michael and Diane discuss how individual susceptibility, health history, genetics, immune function, previous exposures, and other factors can influence how different people respond to the same environment.

And the consequences aren’t purely physical.

Diane talks candidly about the strain chronic illness can place on relationships, particularly when one partner is struggling with symptoms that don’t have an obvious explanation.

Repeated normal test results can make that tension even worse.

The sick partner may feel dismissed or disbelieved. The other person may feel confused, overwhelmed, or unsure how to help. Before long, the illness can begin dominating the relationship itself.

It’s an important reminder that chronic illness rarely affects only the person experiencing the symptoms.

A Diagnosis Should Start a Question, Not End One

One of the strongest moments of the episode has almost nothing to do with mold.

It has to do with the way we think about diagnosis.

Diane argues that medicine often treats a diagnosis as the conclusion of an investigation.

• You have high blood pressure.
• You have IBS.
• You have fibromyalgia.
• You have an autoimmune condition.

Now we know what to call it.

But Diane believes another question should follow:

Why?

• What contributed to this?
• What changed?
• What other systems or exposures might matter?
• What can potentially be addressed upstream?

Michael puts it this way:

“Why are we so focused on diagnosing instead of asking why do I have that diagnosis?”

Diane responds:

“Life is defined by the questions we ask, and we’re not asking the right questions in medicine a lot of times.”

A diagnosis can be enormously valuable. It can provide direction, validation, treatment options, and a common language for what someone is experiencing.

But it doesn’t always have to be the final question.

Sometimes it’s the beginning of a better investigation.

Common Doesn’t Automatically Mean Normal

There is another assumption Diane wants people to question:

That feeling progressively worse is simply part of getting older.

• Fatigue.
• Poor sleep.
• Chronic pain.
• Weight changes.
• Brain fog.

People experience these problems so frequently that it can become easy to accept them without asking whether something else is contributing.

Michael summarizes the distinction: “Just ’cause it’s common doesn’t mean it’s normal.”

Diane immediately agrees.

That doesn’t mean every ache or tired morning requires an exhaustive medical investigation. Bodies change throughout life, and aging is real.

But persistent or disruptive symptoms deserve to be taken seriously rather than dismissed solely because they’re common.

The Bigger Lesson: Keep Asking Better Questions

There is something particularly powerful about hearing Diane tell this story now.

The person sitting across from Michael discussing Lyme, mold, environmental health, testing, and chronic illness is the same person who once sat beneath a tree because she couldn’t remember how to get back to her own house.

She knows what it feels like to have symptoms without an explanation.

And she knows what it’s like to hear that everything looks normal when your lived experience is telling you otherwise.

Her message isn’t to diagnose yourself. It isn’t to assume every unexplained symptom comes from mold. And it isn’t to abandon conventional medicine in search of increasingly obscure explanations.

It’s much simpler:

Keep asking questions.

A diagnosis can be a beginning.

A test result is one piece of information.

Your environment can be another.

And chronic illness may require looking at the entire puzzle rather than waiting for one piece to explain everything.

As Diane says:

“The body doesn’t lie.”

If something feels wrong, that doesn’t tell you what the answer is.

But it may be a reason to keep looking for one.
