Healing the Gut Beyond Food: When The Stress Response Is the Missing Piece

In a recent conversation on the Rich Roll Podcast, one of my "go to" podcasts, Rich Roll and gastroenterologist Dr. Will Bulsiewicz explored a truth many people sense intuitively but rarely hear stated so clearly: you can do all the “right” things for your health—and still not heal—if the body is living in an unaddressed stress or trauma response.

They discussed the deep, often invisible connection between early life stress, stored trauma, the nervous system, and gut health. Trauma here isn’t only acute or dramatic—it includes the quieter, chronic experiences of growing up with emotional insecurity, unpredictability, pressure, or a lack of felt safety. These experiences shape the body long before we have words for them.

Dr. Bulsiewicz explained that the gut is not just a digestive organ, but a signaling and sensory hub, in constant communication with the brain through the vagus nerve, immune pathways, and the microbiome. When the nervous system is stuck in chronic stress, digestion, motility, microbial balance, and gut barrier integrity all suffer. In that state, the body is oriented toward survival, not repair.

One of the most powerful metaphors that came to my mind from the conversation was stress as “the water we swim in.” When stress has been present since childhood, we may not recognize it as stress at all—it simply feels like life and we keep recreating it. Like a fish being asked, “What is water?” the body adapts to its environment, even when that environment quietly drives inflammation, hormonal disruption, and gut dysfunction over time.

This helps explain why someone can eat a pristine diet, exercise regularly, and prioritize sleep, yet still struggle with IBS, autoimmune symptoms, or persistent fatigue. The inputs may be correct, but the internal environment isn’t yet receptive. Healing requires nourishment—but it also requires safety.

Rich and Dr. Bulsiewicz also touched on the spiritual dimension of healing—not necessarily religion, but meaning, purpose, connection, presence, and self-compassion. Practices that help the body feel safe again—somatic work, breathwork, mindfulness, therapy, time in nature, prayer, and integration practices—aren’t optional add-ons. They are often the signal that allows the nervous system to finally stand down.

In my own work with clients, this layer is a deep and essential part of healing—but it’s not where we begin. We first build a solid foothold with nutrition, movement, and foundational lifestyle support. And then, almost inevitably, we arrive here. Because we have to. Without addressing the chronic stress response or stored trauma the body has normalized, true healing often remains out of reach.

I think it's also important to share that this work found me through my own ongoing healing journey, as I learned firsthand how tending to chronic stress and stored trauma can change everything.

From a functional and integrative perspective, this reframes healing in a powerful way. Food is information—but so is our internal state. The gut listens not only to what we eat, but to how we live, how we breathe, how we relate to ourselves, and whether the body feels chronically braced or genuinely supported.

True healing often begins not with doing more, but with listening more deeply—to the body’s history, its patterns, and the places where stress became normalized. When we gently address those layers, the gut doesn’t have to work so hard to speak through symptoms. It finally has the conditions it needs to heal.

Gentle reflection: Where in your life might stress feel so familiar that it’s invisible? And what would it be like to approach healing not as something to fix, but as a process of helping your body feel safe enough to heal?
