The Search for the Perfect Poop: What Our Gut Is Trying to Tell Us About Parkinson’s

There was a time in my life when I never imagined I would spend so much time thinking about something as ordinary, and as overlooked, as poop. And yet, here we are!

Because when you begin to look closely at the body as a system, as an interconnected ecosystem rather than a collection of isolated parts, you start to see patterns. Signals. Clues. And sometimes, those clues show up in the most humble places.

That’s exactly what makes my new book, My Search for the Perfect Poop such a meaningful contribution to this evolving conversation. It invites us to reconsider something we’ve been taught to ignore… and to see it instead as a reflection of our internal terrain.

Listening to the Body’s Quiet Language

For many people, bowel habits are an afterthought, until they aren’t. In the Parkinson’s community, this is especially true.

Long before a tremor appears or a diagnosis is spoken, the body often whispers. Digestive changes. Slower motility. A sense that something isn’t moving as it once did. In fact, constipation and other gastrointestinal symptoms can precede neurological symptoms by years, even decades.

But when we pause here and really sit with this pattern we begin to see something even more profound. Constipation in Parkinson’s is not simply an inconvenience. It is often one of the earliest and most consistent signs that the gut–brain conversation has shifted.

In many individuals, the nerves that coordinate movement in the digestive tract—the enteric nervous system—begin to function differently. The rhythmic contractions that move food along slow down. The colon becomes less responsive. Over time, this creates a kind of internal stagnation.

And yet, there is another layer.

The microbiome itself begins to change. Microbial diversity may decline. Beneficial metabolites, like short-chain fatty acids that help nourish the gut lining and support motility, may be reduced. At the same time, inflammatory signals can increase, subtly reshaping the terrain of the gut.

When we connect these dots, constipation becomes more than a symptom. It becomes a signal of imbalance across multiple systems:

• Neurological signaling

• Microbial ecology

• Immune activity

• Even the integrity of the gut lining

What if these early changes are an important clue that could be reversed?

What if they are the body’s way of asking for support, long before more visible symptoms appear?

My book gently guides readers to ask these questions without fear, and without judgment. It reframes “perfect poop” as an incredibly powerful signpost to our health.  

After all, stool is not just waste. It is information.

The Gut–Brain Conversation

Over the past decade, science has begun to catch up with what many of us sensed intuitively: the gut and the brain are in constant dialogue.

Researchers now describe this as the gut–brain axis, a dynamic communication network involving microbes, metabolites, the immune system, and the nervous system itself.

In Parkinson’s, this connection becomes even more compelling.

Changes in gut motility, like chronic constipation, may influence which microbes thrive and which diminish. In turn, these microbes produce compounds that can either support or disrupt the delicate signaling pathways between the gut and the brain.

Some researchers are even exploring whether misfolded proteins associated with Parkinson’s may originate in the gut and travel along the vagus nerve to the brain. While this research is still evolving, it reinforces a powerful idea: what happens in the gut does not stay in the gut. It echoes outward.

From Observation to Empowerment

I wrote My Search for the Perfect Poop to be grounded in observation. Not fear-based, not obsessive tracking, but a return to awareness.

Because when we begin to notice patterns like frequency, form and ease, we reconnect with something fundamental: the body’s innate intelligence.

We begin to ask better questions:What is my microbiome asking for?How do my daily choices shape this internal ecosystem?Where might imbalance be quietly taking root?

And perhaps just as importantly: what happens when things slow down, and why?

Constipation, in this light, becomes something we can learn from rather than simply manage. And from those questions, something powerful emerges: not control, but participation.

A Systems Perspective on Healing

My own journey into microbiome science began with my husband John’s Parkinson’s diagnosis. It led me down a path of asking not just what is broken, but what system is out of balance?

That shift changes everything.

Because when we see the body as a system:The gut is not separate from the brainThe microbiome is not separate from the immune systemOur environment is not separate from our biology

It’s all connected. And something as simple, and as overlooked, as constipation becomes a window into that complexity. Not something to dismiss, but something to understand. A daily, tangible feedback loop.

This book meets people right at that intersection of science and lived experience with a little humor mixed in. I mean, who doesn’t like a good poop joke!  It invites you to think about this daily habit in a new way.  

A Gentle Invitation

If there’s one thing I’ve learned along this journey, it’s that transformation rarely begins with dramatic interventions. It begins with awareness, curiosity, and a willingness to look where we were once taught not to look.

My Search for the Perfect Poop is not really about perfection. It’s about reconnection to the rhythms of the body, to the signals we’ve ignored, and to the possibility that even the most ordinary functions can guide us toward greater balance.

And for those navigating Parkinson’s or supporting someone who is, this perspective offers something some deeper understanding.

The science of the microbiome is still unfolding, but one thing is clear: when we begin to listen to the gut, we are often hearing the first chapter of a much larger story.

And sometimes… that story begins with poop.
