The Enteric Nervous System
After a beautiful week of helping my fellow therapists dive deeper into the enteric nervous system, I realized how many of us may not fully understand this incredible inner steward. It is quiet, vigilant, and continually tracking our inner terrain. How often does this system get overlooked?
Most people know it as “the gut.” The stomach. Digestion. Something that should quietly do its job in the background as long as we eat well enough and manage stress properly. But the enteric nervous system is not passive, and it is not secondary. It is intelligent. It is responsive. And it is deeply involved in how we experience safety, emotion, and regulation.
This inner caretaker lives entirely within the digestive tract, stretching from the esophagus to the colon, woven through layers of smooth muscle and connective tissue. It contains hundreds of millions of neurons, more than the spinal cord itself. Communicating constantly with the brain, the heart, and the immune system, yet it can function on its own. It makes decisions. It adapts. It remembers.
The enteric nervous system manages digestion, yes, but it also monitors threat, modulates stress responses, and plays a decisive role in emotional processing. It is exquisitely sensitive to rhythm, environment, and touch. That is why emotions so often show up in the belly before they reach our lips.
Anxiety often tightens the belly before fear ever finds words, and grief dulls appetite before the heart understands what has been lost. And under chronic stress, the gut becomes a holding place.
When the nervous system perceives a threat, resources are diverted from digestion. Blood flow shifts, stress hormones rise, and peristalsis slows or becomes erratic. The microbiome adapts to a body preparing for survival instead of nourishment. Over time, this state becomes familiar, and familiarity begins to feel like a baseline.
Because the enteric nervous system does not respond to logic or reassurance, you cannot talk it into safety; it learns through sensation, through rhythm, through the difference between being rushed and being met. It is exquisitely attuned to touch, pace, and presence, just as any living creature would be.
This is why the belly is such a powerful place to begin.
Research consistently shows that gentle, intentional abdominal contact increases parasympathetic activity, improves vagal tone, and supports heart rate variability. Stress chemistry begins to soften, digestion improves, and inflammation quiets. The nervous system receives a clear message that it no longer has to stay on guard.
What many of us don't realize is that most of the body’s serotonin is produced in the gut. Mood, sleep, and emotional resilience are intimately tied to this system. When the enteric nervous system is overwhelmed, even the most self-aware person can feel emotionally unsteady. When it feels safe, things begin to reorganize quietly, often without conscious effort. This is why I return here again and again within my work.
Not to uncover stories, or to chase emotional release, but to honor the system that has been carrying a heavy load from the very beginning. The system that adapts silently, holds stress without complaint, and keeps the body moving forward when life demands more than feels possible.
The abdomen is not just another place to work, but a neurological crossroads, a sensory hub, and often the first place the body tells the truth. When we understand this, our touch, our pacing, and our outcomes change.
Tomorrow, I want to take you further into this landscape and show you how abdominal work becomes a conversation rather than a technique, and why beginning here can change everything that follows.
