Stomach pain in children is often dismissed as nerves or growing pains. But for thousands of children diagnosed with functional abdominal pain (FAP) or irritable bowel syndrome (IBS), the discomfort is very real — and very persistent. A landmark clinical trial published in Gastroenterology suggests hypnotherapy could be the most effective treatment available, with results that hold up for years after the sessions end.
The Study: A Randomised Controlled Trial in Children With FAP
Researchers Arine Vlieger and colleagues at the St. Antonius Hospital in the Netherlands conducted a rigorous RCT with 53 children aged 8–18 who had chronic functional abdominal pain or IBS. Children were randomly assigned to either gut-directed hypnotherapy (five sessions over three months) or standard medical care with supportive therapy.
The hypnotherapy protocol focused specifically on the gut-brain connection — using relaxation techniques, imagery, and direct suggestions to calm intestinal sensitivity and reduce the brain's amplification of pain signals. Each session lasted 30–60 minutes and was tailored to the child's age, using age-appropriate visualisations like imagining a river flowing calmly or a dimmer switch turning down discomfort.
What the Researchers Found
The results were striking. At the end of the three-month treatment period, 87% of children in the hypnotherapy group showed significant clinical improvement in pain frequency and intensity — compared to just 52% in the standard care group. But what made the study genuinely exceptional was the follow-up data.
Five years later, the research team tracked the same children down. The hypnotherapy group had maintained their gains remarkably well. Around 68% remained in clinical remission five years after completing treatment — compared to only 20% of those who received standard care. The 2012 follow-up paper, also published in Gastroenterology, confirmed that a few sessions of gut-directed hypnotherapy in childhood created lasting changes in how the gut and brain communicate pain.
Why Functional Abdominal Pain Is So Hard to Treat
FAP and IBS are classified as disorders of gut-brain interaction. There is no structural damage — no infection, no inflammation visible on scans — but the pain is entirely real. The nervous system becomes hypersensitive, amplifying normal gut sensations into significant discomfort. Standard medical approaches often offer limited relief because they target the gut directly, while the root of the problem lies in the signalling between the gut and the brain.
Hypnotherapy addresses this at the right level. By inducing a deeply relaxed state and delivering targeted suggestions during that state, it can reduce the brain's threat response to gut sensations, lower visceral hypersensitivity, and help the nervous system return to a calmer baseline. The Vlieger trial was among the first to demonstrate this mechanism working reliably in children — and the five-year follow-up showed the changes were not just temporary relief but genuine recalibration.
What This Means Beyond Children
While the trial focused on children and adolescents, its implications extend to adults with IBS and functional gut disorders too. The gut-brain axis works the same way across the lifespan. The study reinforced what gastroenterologists were beginning to recognise: that psychological approaches targeting the nervous system can achieve what medications and dietary interventions often cannot.
For adults dealing with gut-related anxiety, IBS, or stress-driven digestive issues, the same underlying mechanisms apply — and hypnotherapy works on all of them.
How Clear Minds Can Help
The Clear Minds app uses evidence-based hypnotherapy sessions developed around the same gut-brain principles explored in the Vlieger research. Whether you are managing IBS, stress-related digestive symptoms, or the anxiety that often accompanies gut discomfort, the sessions are designed to calm the nervous system, reduce hypersensitivity, and restore a more balanced relationship between mind and body.
You do not need five clinic visits. A guided session through the app, listened to in a quiet space, can begin the same process of nervous system recalibration that produced such impressive results in the trial.

The Takeaway
A well-designed RCT with a five-year follow-up is about as strong as clinical evidence gets. The Vlieger study did not just show that hypnotherapy reduced pain in children with functional abdominal pain — it showed the effect was durable, meaningful, and far superior to standard medical care over the long term. For a condition that affects up to 25% of school-age children and frequently persists into adulthood, that is a finding worth paying attention to.
The gut and the brain are in constant conversation. Hypnotherapy, it turns out, is one of the most effective ways to change what they are saying to each other.
