What Is GI Psychology and Who Does It Help?
You have probably spent more time than you can count tracking what you eat, reading ingredient labels, trying elimination diets. You have done the low-FODMAP protocol. You have had the scopes. Some of it helped a little. None of it got you all the way there.
What nobody mentioned is that the gut does not operate independently of the rest of you. Not your stress, not your history, not the years of running on empty. The gut and the nervous system are in constant communication, and when that relationship breaks down, dietary changes alone are rarely enough to fix it.
That is what brought GI psychology into existence.
The Gut-Brain Connection
The enteric nervous system contains more neurons than your spinal cord. It communicates bidirectionally with your brain through the vagus nerve, meaning signals travel both ways. Stress, grief, unprocessed experience, and chronic anxiety all influence gut motility, pain perception, and how your body responds to treatment. This is documented physiology, not a theory.
For people living with IBS, IBD, SIBO, GERD, and functional GI disorders, this matters clinically. Psychological interventions consistently improve GI symptom severity, quality of life, and treatment response. Not because your symptoms are psychological in origin, but because your nervous system is involved in both experiences and addressing that dimension changes outcomes.
What Living With a GI Condition Actually Looks Like
It is planning your day around bathroom access. It is the low-grade anxiety that travels with you to every restaurant, every long drive, every social event you almost canceled. It is the grief of a life that has quietly gotten smaller, and the exhaustion of explaining yourself to people who cannot fully understand what they cannot see.
By the time most people find their way to a GI psychologist, they have been managing all of this largely alone. The medical appointments address the physiology. Nothing addresses the rest of it.
Working with a GI Psychologist
At Embody Health Psychology the approach draws on IFS, Somatic Experiencing, psychodynamic therapy, and CBT depending on what your specific situation calls for. Some people need to work with the anxiety and avoidance that have built up around their symptoms. Some need to process the grief and identity disruption of a diagnosis that changed their life. Some need to work with a nervous system that has been in a chronic stress response for so long it has forgotten how to regulate.
Most people need some combination of all of it.
What Becomes Possible
Reduce the anxiety and anticipatory fear that travels with your symptoms everywhere you go
Break the stress-symptom cycle that dietary changes alone cannot interrupt
Process the grief of a life that has been shaped by your diagnosis
Return to activities, places, and experiences you have been avoiding
Develop a relationship with your body that is not defined entirely by what it cannot do
Communicate more effectively with your medical team about the full picture of your experience
If you are living with a GI condition and the medical management has only gotten you part of the way there, a free consultation with Embody Health Psychology is a place to start.

I’m Dr. Mariah Streeter, a licensed clinical psychologist and the founder and clinical director of Embody Health Psychology in Miami, Florida. Our practice works with adults living with chronic illness, gastrointestinal conditions, and the medical experiences that come with them, offering therapy and psychological evaluation across Florida and in PSYPACT-participating states.
We integrate Internal Family Systems, Somatic Experiencing, and psychodynamic relational therapy, which means our clinicians go beneath symptom management to the patterns underneath. That is often what makes the difference for people who have already tried skills-based treatment and found it wasn’t enough.
As a health psychologist, I have more than a decade of clinical experience treating people whose lives have been reshaped by medical illness, and I live with chronic illness myself. I have experience reading medical charts, I know the terminology, and I have sat on both sides of the exam room. What you get here is someone who is already listening.
