Many people are surprised to learn that their digestive symptoms—like nausea, bloating, constipation, or abdominal pain—may be directly linked to past trauma or chronic stress. The truth is, your gut and your brain are in constant communication through the gut brain axis, and when you’ve lived through overwhelming experiences, that connection can become disrupted. This disruption in gut brain interaction can play a meaningful role in ongoing gastrointestinal symptoms.
At GI Psychology, we specialize in integrative GI care that treats both the psychological and physical dimensions of gut health, especially for those whose symptoms may be rooted in trauma.

The Gut–Brain Connection in Trauma
The gut–brain connection is a powerful communication network between your digestive tract and central nervous system. Trauma—whether from childhood experiences, medical procedures, or ongoing stress—can have lasting effects on both mental health and gastrointestinal (GI) function by altering how the gut brain axis regulates digestion, sensation, and stress responses.
Research shows that trauma can:
- Alter the gut microbiome, reducing beneficial bacteria that support emotional and physical health
- Disrupt the nervous system, increasing gut sensitivity and reactivity
- Raise levels of inflammation, which can lead to chronic GI symptoms
- Trigger changes in neurotransmitters like serotonin, impacting both mood and digestion
For many people, these disruptions manifest as disorders of gut–brain interaction (DGBIs)—such as irritable bowel syndrome (IBS), functional dyspepsia, chronic nausea, or non-cardiac chest pain. While traditional GI treatments may help manage symptoms, they often don’t address the underlying trauma that continues to influence gut–brain signaling.
Why Integrative GI Care Is Essential
If you’ve been told “it’s just stress” or “everything looks normal,” but your symptoms persist, you’re not alone—and you’re not imagining it. Integrative GI care looks deeper, combining psychological expertise with evidence-based digestive health support to provide disorder of gut-brain interaction treatment that addresses the whole person.
At GI Psychology, our trauma-informed approach helps patients:
- Understand how past experiences shape gut responses
- Reduce anxiety-driven symptom spirals
- Rebuild trust in their bodies
- Develop skills to regulate the nervous system and improve GI function
How We Support Healing
Our work goes beyond symptom management. We help restore balance in the gut brain axis through personalized care, which may include:
- Trauma-informed psychotherapy (CBT, ACT, clinical hypnosis, or EMDR)
- Mind–body strategies that calm the vagus nerve and reduce gut reactivity
- Collaboration with GI specialists and other members of your care team to create a unified treatment plan
Whether your trauma is recent or decades old, healing is possible—with the right tools and support.
