Hypnotherapy: A Dietitian’s 10-Year Personal Account and What the Research Now Shows
If I had to name one of the most life-changing things I have ever done for my health – alongside MRT food sensitivity testing, targeted nutrition, and the functional medicine path I have built my career around – hypnotherapy is at the very top of that list. And after 10 years, I still say that without hesitation.
I originally wrote this post a few years after my first hypnotherapy session, full of the excitement of fresh discovery. Now, a decade later, I am coming back to update it with something more valuable: lived proof that the benefits are not a honeymoon phase. They last. They compound. And the science has caught up in remarkable ways.
I am Heidi Moretti, MS, RD, CLT – a registered dietitian with 25 years of clinical experience specializing in functional nutrition, gut health, and integrative medicine. I say that not to impress you, but because it matters for this story. I am the person who digs into research, who questions everything, and who was deeply skeptical of anything that smelled like “woo.” And yet, hypnotherapy – working with my hypnotherapist Clark Patton at Inner Wisdom Missoula – changed my life more profoundly than almost anything else I have professionally or personally encountered.
In fact, hypnotherapy is part of why this blog exists at all. Working with Clark helped me understand, at a subconscious level, that I needed to follow the path that was true to my own beliefs – that functional and integrative medicine, root-cause nutrition, and the mind-body connection were not just interesting ideas but the work I was meant to do. That clarity gave me the courage to start writing, to share what I was learning, and to build The Healthy RD into what it is today. Sometimes the most important breakthroughs are the ones that redirect your whole direction in life.
If you have struggled with chronic pain, anxiety, racing thoughts, or feeling stuck in patterns you cannot break through willpower alone, this is for you.

A Decade Later: The One Thing That Changed My Life the Most
Ten years is a long time to evaluate anything. Diets trend and fade. Supplements come in and out of the research spotlight. But hypnotherapy – specifically working with Clark Patton, a remarkable hypnotherapist here in Missoula, Montana – has remained the single greatest contributor to my wellbeing, alongside MRT food sensitivity testing, which helped me identify the hidden dietary triggers that were fueling chronic inflammation in my body.
When I first wrote about my hypnotherapy experience, I had been through a handful of sessions and was floored by the results – particularly the near-elimination of menstrual pain I had endured for 30 years. That benefit has held. But what I did not fully anticipate at the time was how deeply hypnotherapy would continue to reshape my inner world, my response to stress, and my capacity to navigate life’s harder chapters from a place of grounded calm rather than reactivity.
Most recently, I returned to see Clark in a significant transitional period – leaving a job in a way that did not damage me or the people around me. I work in a clinical environment, as many of you know, and I had dysfunctional coworkers and real professional pressures that, left unaddressed in the subconscious, could easily have led to a destructive exit – the kind of impulsive, emotionally-charged decision-making that leaves wreckage behind. Instead, I went back to the work I knew from years of practice. I used hypnotherapy to process, to clarify, and to leave from a place of integrity and self-respect. I walked away from that chapter whole.
That, to me, is the real proof. Not just the original pain relief, which I still marvel at. But the capacity to use these tools – and this relationship with a gifted hypnotherapist – to move through major life events with grace. That is what root-cause healing looks like in practice. Not just fixing a symptom; rewiring how you meet the world.
Most recently, I returned to Clark with a question that came directly out of my work with MRT food sensitivity testing. I wanted to explore whether hypnotherapy could help reduce my inflammatory reactions to foods – to work on the subconscious layer underneath the immune reactivity. What came up in that session genuinely surprised me, even after a decade of this work. I realized that I have a deep tendency to eat voraciously when I love something – an all-or-nothing relationship with food that goes back to childhood. I can trace it clearly now: as a small child in the raspberry patch, I would graze nonstop, eating until I felt sick. I did not have an off switch. I thought I was eating healthfully as an adult – and I was, mostly – but the pattern was still there. I would overeat even healthy foods, cycling through them intensively until my body reacted. That, I now believe, is part of the root cause of some of my own food sensitivities. Overconsumption of even wholesome foods, repeated over time, can drive immune sensitization.
This is the kind of insight you cannot get from a lab test or a nutrition textbook. It lives in the subconscious, in the stories and patterns formed long before we had words for them. Hypnotherapy created the space to see it clearly – and with that clarity came the ability to change it. I no longer need food to be all or nothing. I can enjoy raspberries without eating myself sick. That sounds small. It is not small at all.
I tell every client who comes to me through The Healthy RD that the mind-body connection is not an optional add-on to healing. It is foundational. You cannot fully fix the gut, the hormones, or the immune system while the nervous system is running a chronic stress program underneath everything. Hypnotherapy is one of the most powerful tools I know to address that layer.
What Hypnotherapy Actually Is – Setting the Record Straight
When I first mentioned my experience with hypnotherapy to coworkers, the responses were predictable. “Isn’t that sketchy?” “You have to be careful – some of those people are out there.” Even clinicians I respect had doubts rooted in misconceptions.
Let me be direct: hypnotherapy is not stage performance, not mind control, and not pseudoscience. According to the Mayo Clinic, hypnosis conducted by a trained therapist or health professional is considered a safe, complementary, and evidence-supported treatment. That assessment has not weakened over time – if anything, the research base has strengthened dramatically.
What actually happens in a hypnotherapy session is a state of focused, receptive awareness – sometimes described as “meditation with a PhD” – in which the critical, analytical mind quiets down enough for the subconscious to become accessible. The hypnotherapist guides you using language, imagery, and suggestion to shift deep patterns of thought, perception, and response. You are not asleep. You are not under anyone’s control. You are, in fact, extraordinarily present.
The most important concept I learned through this work is embedded in the word “decide” itself. From the Latin “de cidere” – to cut off. Through hypnotherapy, I cut off the mental loops, the inner critic, the subconscious narratives that were keeping me contracted. That is not metaphor. That is neurological change, as the research now confirms.
How My Hypnotherapy Journey Began: A 40-Something Dietitian with Chronic Pain
My most joyous time in life is in my forties and fifties, and I mean that completely. Less pain, happier, healthier, and more at peace than I ever was in my twenties or thirties. When I was twenty, I had physical health on my side – energy and resilience – but inside, there were nagging doubts, anxiety, and a kind of chronic emptiness that no amount of “doing the right things” could fill. I ate well. I exercised. I had a loving family and a comfortable home. And yet something was persistently off in my inner world.
A coworker once said, “You always seem so confident.” What they could not see was the internal narrator telling a different story.
I first sought out hypnotherapy for help with motion sickness – a lifelong limitation that had quietly constrained my life more than I wanted to admit. What happened instead was a cascade of unexpected benefits that I could not have predicted. After my third session with Clark Patton, I noticed that my cycle – historically the source of 30 years of debilitating pain and industrial quantities of ibuprofen – had become, for the first time in my adult life, manageable. Then nearly pain-free.
I want to be honest about this: I do not believe the pain was “all in my head.” Chronic pelvic pain is real, physiological, and rooted in inflammation and nervous system sensitization. What hypnotherapy does is modulate the neuroendocrine response – lowering the inflammatory signaling, reducing cortisol, and restoring regulation to a system that had been running hot for decades. The research now explains the mechanism with far more precision than it did when I started. But I had the lived data first.
What the Latest Research Says About Hypnotherapy
As a dietitian and researcher, I have a professional obligation to check whether what I experienced has scientific backing. I am happy to report that the research base for hypnotherapy has expanded substantially since I wrote this post originally – and it supports what I observed in my own body and now recommend to clients.
Research summary compiled from peer-reviewed publications 2024-2026. Sources cited throughout this article.
Pain relief: A comprehensive 2025 meta-analysis published in the Journal of Clinical Medicine analyzed 12 randomized controlled trials involving chronic and acute pain and found that medical hypnosis reduced acute pain compared to standard care with a statistically significant medium effect size. A separate 2024 systematic review in PAIN Reports pooled 70 RCTs (n=6,078 patients) and found that hypnosis used alongside standard care produced additional measurable pain reduction across chronic pain, surgical pain, and burn wound care conditions. This is not a fringe finding. This is robust, replicated evidence.
Gut health and IBS: For those with irritable bowel syndrome, the case for hypnotherapy has become particularly strong. A 2025 meta-analysis in Neurogastroenterology and Motility (Adler et al.) reviewed 12 studies covering 1,158 IBS patients and found that gut-directed hypnotherapy improved global IBS symptoms compared to comparators in all 12 studies. It specifically improved pain compared to other standard IBS interventions. As a dietitian who has worked with hundreds of IBS patients, this matters enormously to me. The gut-brain axis is not just a metaphor – the communication between the enteric nervous system and the brain is bidirectional, and hypnotherapy directly targets that signaling. My own gut health has been substantially improved through this combination of MRT-guided diet and hypnotherapy working together.
Cortisol and hormones: This is the piece I found most compelling when I first wrote about hypnotherapy, and the research has only deepened since. A 2026 study published in Scientific Reports found that hypnotic safety suggestions reduced the cortisol awakening response and morning heart rate in daily life. Research published in Frontiers in Psychology in 2025 demonstrated that during active-alert hypnosis, cortisol decreased while oxytocin increased – particularly notable for individuals with lower hypnotizability, who are often the people who most need help with nervous system regulation. As I wrote in my book Cortisol Fix, cortisol dysregulation is at the root of dozens of modern health problems. Hypnotherapy is one of the few interventions that can directly modulate the hypothalamic-pituitary-adrenal axis through the mind alone.
Mental health and behavior change: A 2026 systematic review of Ericksonian hypnotherapy across 8 RCTs (n=676) published in MDPI found consistent, significant symptom reductions across acute pain, depression, grief, IBS, disordered eating, and alcohol use. This client-centered, individualized approach – which is exactly what Clark Patton practices – is gaining significant traction in clinical research. A 2024 editorial in Frontiers in Psychology called hypnosis a powerful and valuable tool in psychotherapy and medicine, with applications from chronic pain to oncology support.
The Cortisol Connection: Why Hypnotherapy Works at a Root-Cause Level
One of the things I have spent years helping people understand – through my writing at The Healthy RD, through my clinical practice, and through my book Cortisol Fix – is that chronic elevated cortisol is the thread running through most of the chronic conditions my clients struggle with. Chronic pain and inflammation, mood and mental health challenges, hormonal imbalances, gut dysbiosis, immune dysfunction – elevated cortisol is involved in all of them.
Diet matters. Supplements matter. Sleep and exercise matter. But if the nervous system is running a chronic stress program – looping old stories, bracing for threats that are no longer present, activating the HPA axis in response to psychological triggers – you cannot fully resolve any of these conditions through physical interventions alone.
This is where hypnotherapy functions as a root-cause tool rather than a symptom manager. By working directly with the subconscious – where automatic threat responses live – it can interrupt the stress activation cycle at its source. Research now confirms that hypnotherapy measurably lowers cortisol. It activates the parasympathetic nervous system. It shifts the gut from fight-or-flight reactivity into rest-and-digest regulation. And it does this not just in the moment of the session, but through the rewiring of habitual neural patterns over time.
This is why the benefits I experienced – and that I hear about from clients who pursue it – are not temporary. They accumulate. Ten years in, I am still benefiting from the work I did in those early sessions, and I continue to return to Clark when I face genuinely hard things.
Hypnotherapy and the Gut-Brain Axis: A Functional Dietitian’s Perspective
As a gut health specialist, the gut-brain axis is something I talk about constantly. The Rome Foundation describes it as a bidirectional communication system between the central and enteric nervous systems – linking emotional and cognitive centers of the brain directly to gut function. When stress is chronically elevated, this system becomes dysregulated – intensifying pain signals, altering motility, increasing gut permeability, and worsening inflammation.
What this means in practice: even a carefully designed MRT-guided gut healing protocol works so much better when you are also addressing the subconscious stress patterns that keep the gut-brain axis in a state of chronic activation. Diet is powerful – but pairing it with nervous system work is where the real breakthroughs happen.
Gut-directed hypnotherapy, reviewed extensively in a 2024 mini-review published in Frontiers in Psychology, is now considered one of the most effective psychological therapies for IBS – recommended by NICE for patients who do not respond to conventional IBS medications after 12 months. A 2025 systematic review covering 41 IBS studies found significant improvements in abdominal pain, flatulence, diarrhea, constipation, and general wellbeing.
I combine gut-directed principles with the broader personal growth work I do with Clark Patton. The results in my own gut health have been remarkable – and they mirror what I now see when clients pursue this alongside their nutrition protocols.
How clinical hypnotherapy works from a neurobiological standpoint – based on current research in pain science, neuroendocrinology, and gut-brain axis studies.
Hypnosis for Chronic Pain: What 10+ Years of Research Shows
When I first wrote about the pain research, I cited 13 positive studies. The evidence has grown considerably since then. A 2025 meta-analysis in the Journal of Clinical Medicine systematically reviewed 12 RCTs from 2014 to 2024, examining both acute and chronic pain. The finding was clear: medical hypnosis reduced acute pain by a medium and statistically significant effect compared to standard care, and also reduced opioid consumption – making it particularly relevant in the context of the current opioid crisis.
A separate 2024 systematic review in PAIN Reports pooled data from 70 randomized trials (n=6,078) and found meaningful additional pain reduction when hypnosis was added to standard care across chronic pain, surgical pain, and burn care contexts.
The conditions showing consistent benefit include chronic back pain, arthritis, fibromyalgia, neurological pain, and gynecologic pain. Every single one of those conditions also involves dysregulation of the stress and cortisol response. That is not coincidence. That is mechanism.
I am 52 now (happily), and the pain relief I found through hypnotherapy has held across a decade that included a professional career, family life, and all the physical demands that come with an active life in Montana. I have not needed to resort to the ibuprofen cycle I was locked into before. That, as a functional dietitian who cares deeply about the GI tract and kidney-protective eating, is a meaningful outcome in itself.
Hypnotherapy and Hormone Balance: The Cortisol-Repair Connection
I have come to understand through both research and personal experience that emotional stress is not merely psychological – it is hormonal. Chronic stress drives cortisol dysregulation, which then disrupts progesterone, estrogen, thyroid function, insulin sensitivity, and gut integrity in a cascade that conventional medicine tends to treat one piece at a time rather than at the root.
The research is increasingly clear that hypnotherapy measurably intervenes in this cascade. Published data confirms that hypnotherapy reduces cortisol levels and improves psychological wellbeing including anxiety and depression. A 2025 study published in Frontiers in Psychology specifically examined oxytocin and cortisol changes during hypnosis, finding that cortisol decreased while oxytocin – the bonding, repair, and calm hormone – increased. Even participants with lower baseline hypnotizability showed significant hormonal shifts.
For women navigating hormonal transitions – perimenopause, menstrual dysfunction, thyroid irregularities – this is highly relevant. Clinical hypnosis has been shown in research to directly reduce hot flash frequency and severity, outperforming cognitive behavioral therapy on physiological measures. For me personally, the near-elimination of menstrual pain through hypnotherapy, before I had the language to explain it, was my first clue that the body and mind were not two separate systems to be managed independently.
I want to be clear that hypnotherapy is not the only tool I use for menstrual and hormonal health – it works best as part of a complete functional nutrition approach. On the nutritional side, I use several targeted nutrients that directly support hormone balance and reduce menstrual pain. Vitamin A is one of the most underappreciated – research shows it can reduce heavy periods in the majority of women who use it, and vitamin A deficiency is directly linked to abnormal menstrual patterns. Iron is equally critical: heavy periods deplete iron, and low iron perpetuates the hormonal dysfunction that makes periods worse – a vicious cycle that is easily missed in conventional care. And for the deeper hormonal foundation, DHEA – the parent hormone to estrogen, progesterone, testosterone, and cortisol – can be a game-changer for women whose hormone levels have bottomed out, particularly in perimenopause. I have personal experience with all three, and I write about each in depth on The Healthy RD. The combination of hypnotherapy to calm the neuroendocrine stress response with these targeted nutritional supports is the most powerful approach I have found for restoring hormonal balance from the ground up.
Self-Hypnosis: Carrying the Practice into Daily Life
One of the most empowering gifts of working with a skilled hypnotherapist is that you learn to access these states yourself. The self-hypnosis tools I learned from Clark Patton in my first years of work have become part of my daily vocabulary – how I meet stress, how I process difficult situations, how I prepare for challenging interactions at work, and how I recover from them.
A large-scale 2025 study published in npj Digital Medicine examined self-hypnosis for stress management across 84,395 users logging 282,893 sessions and found significant, immediate reductions in stress scores. This scale of evidence for a mind-body practice is unusual and noteworthy. It reflects that the mechanisms underlying hypnotherapy are reliable and teachable – not dependent on rare talent or exceptional suggestibility.
My experience matches this. The techniques I was taught – breath, focused attention, subconscious dialogue, reframing the inner narrative – are tools I use every week. When I returned to Clark most recently to navigate my workplace transition, much of what made those sessions powerful was that I came in already practiced. We could go deeper, faster, and with more precision, because the foundation was already built over years.
Is Hypnotherapy Safe? What to Know Before You Start
The Mayo Clinic categorizes hypnotherapy as a safe complementary medical treatment when conducted by a trained professional. Current research – including a 2025 review in the International Journal of Clinical and Experimental Hypnosis – supports this assessment. Side effects are rare and typically limited to mild dizziness or emotional processing that can arise during deep work.
A note I want to make: hypnotherapy may not be appropriate for individuals with certain severe mental health conditions, including psychosis or dissociative disorders. If you have a complex mental health history, please work with your healthcare provider to assess appropriateness. For the vast majority of people dealing with chronic pain, stress, anxiety, digestive issues, hormonal challenges, or stuck behavioral patterns – the risk profile is low and the potential benefit is high.
Choosing a practitioner matters. I was extraordinarily fortunate to find Clark Patton at Inner Wisdom Missoula. He is, without exaggeration, one of the most insightful and gifted people I have ever had the privilege of working with. His approach combines deep skill with genuine compassion – the kind of human wisdom that cannot be reduced to a technique. If you can find someone of that quality in your area, go. Do not hesitate.
For those outside Missoula, look for practitioners with formal training in clinical or medical hypnosis – credentials through the American Society of Clinical Hypnosis (ASCH) or the National Guild of Hypnotists are good markers. A trustworthy practitioner will explain the process clearly, never make you feel out of control, and will teach you self-hypnosis tools you can use independently.
The Two Things That Changed My Life Most: Hypnotherapy and MRT Testing
When I reflect on the full arc of my health journey, two interventions stand clearly above everything else. The first is hypnotherapy with Clark Patton. The second is MRT food sensitivity testing through the LEAP protocol, which I now use with clients through The Healthy RD.
The reason these two work so synergistically is that they address different layers of the same root-cause system. MRT identifies the specific foods and food chemicals that are driving immune activation and inflammatory mediator release in your unique body – eliminating the dietary inputs that are constantly triggering your immune system. Hypnotherapy addresses the nervous system layer – the chronic stress activation, the neuroendocrine dysregulation, the emotional patterns that keep cortisol elevated and the gut-brain axis in fight-or-flight mode.
Remove the dietary inflammatory triggers. Calm the nervous system. Let the gut, the hormones, and the immune system finally repair. That is the model I use, and it is the model that has produced the most lasting results in my own health and in my clinical practice.
If you want to explore whether MRT testing is right for you, I encourage you to read more about MRT and gut healing at The Healthy RD. And if you are in Montana or can travel to Missoula, Clark Patton at Inner Wisdom Missoula is where I would send my own family members.
Frequently Asked Questions About Hypnotherapy
No. Stage hypnosis is entertainment. Clinical hypnotherapy is a therapeutic practice used in hospitals, medical centers, and private clinical settings to address pain, anxiety, gut health, trauma, and behavioral change. The Mayo Clinic and NIH both recognize clinical hypnosis as evidence-based. You are not made to perform or act against your will – you are in a focused, receptive state, fully aware of your surroundings.
This varies widely by goal and individual. For specific issues like pain relief or a particular phobia, some people experience meaningful change within 3-6 sessions. For deeper personal growth work – the kind I have done over 10 years – it is an ongoing relationship and practice. Research suggests that more intensive programs with greater frequency and personalized suggestions produce significantly better outcomes.
Yes, and the research is robust. Gut-directed hypnotherapy is now recommended by NICE for IBS patients who have not responded to medications after 12 months. A 2025 meta-analysis covering 1,158 IBS patients found it improved global symptoms, pain, and wellbeing across 12 studies. It works by calming the gut-brain axis and reducing visceral hypersensitivity.
Yes. Multiple studies – including a 2026 paper in Scientific Reports and a 2025 study in Frontiers in Psychology – confirm that hypnosis measurably reduces cortisol levels and the cortisol awakening response. It simultaneously increases oxytocin. These hormonal shifts are part of why the effects of hypnotherapy extend so broadly across conditions rooted in chronic stress, including pain, gut health, hormonal imbalances, and mood.
Yes, when practiced by a trained professional. The Mayo Clinic classifies it as safe and complementary. Serious adverse effects are extremely rare. It is generally not recommended for individuals with active psychosis or certain severe dissociative disorders – consult your healthcare provider if you have a complex mental health history.
Absolutely, and a good hypnotherapist will teach you. Self-hypnosis is one of the most valuable skills I have carried from my work with Clark Patton. A large 2025 study published in npj Digital Medicine found significant stress reduction effects from self-hypnosis sessions across tens of thousands of users. The techniques are learnable and effective for ongoing stress management between formal sessions.
They share some qualities – both involve quiet mind and focused awareness – but hypnotherapy is more directive. A skilled hypnotherapist uses language and suggestion to actively work with subconscious patterns, which makes it more efficient for specific goals. I have described it as “meditation with a PhD.” Many people who have struggled with traditional meditation – racing thoughts, inability to quiet the mind – find hypnotherapy more accessible and immediately impactful.
