One of the barriers to gut-brain therapy has historically been access – traditional gut-directed hypnotherapy requires a trained specialist, often over a costly 6–12 weekly sessions in person, which can really add up.⁹ For many people searching for a lasting answer to IBS, that has put the most effective approach out of reach.
Digital programs have changed this. Nerva delivers a structured 6-week gut-brain therapy protocol – combining gut-directed hypnotherapy, cognitive behavioral techniques, breathing exercises, and symptom tracking – in 15–20 minutes per day.
In a randomized controlled trial published in the American Journal of Gastroenterology, 81% of participants achieved a clinically significant improvement on the IBS Symptom Severity Scale, and 71% had a clinically significant reduction in abdominal pain.¹¹
While it is not a cure, the evidence suggests that addressing the gut-brain connection directly is the most reliable path to lasting relief – and programs like Nerva have made that path accessible for the first time.
"If we do a good job managing the disruption between the gut-brain axis, many patients will have kind of mild to no symptoms the majority of the time, and that's really our goal." – Morgan Binder, Physician's Assistant and Registered Dietitian, Arizona Digestive Health
Frequently asked questions
Does IBS ever go away completely?
IBS can go into long periods of remission where symptoms are minimal or absent entirely. Population studies suggest that 30–45% of people experience extended symptom-free periods within the first year of diagnosis, and some people – particularly those with post-infectious IBS – may see symptoms resolve over several years.⁴
Does IBS get worse with age?
IBS prevalence actually tends to decrease with age, and research shows that visceral hypersensitivity – a key driver of IBS pain – becomes less common in older adults.¹² However, the condition is unpredictable and can fluctuate with changes in stress, diet, or overall health at any stage of life.
What is the difference between IBS and IBD?
IBS and IBD are not the same. IBD (Inflammatory Bowel Disease), which includes Crohn's disease and ulcerative colitis, involves visible inflammation and structural damage to the digestive tract, while IBS is a functional condition where the gut looks normal on tests but the nervous system processes digestive signals abnormally.⁵
Can gut-directed hypnotherapy help with all types of IBS?
Gut-directed hypnotherapy has been shown to improve symptoms across IBS subtypes, including IBS with diarrhea (IBS-D), constipation (IBS-C), and mixed patterns (IBS-M).¹ Because it works on the gut-brain connection rather than targeting a specific symptom, the benefits apply regardless of which bowel pattern predominates.
How quickly will I feel better after gut-brain therapy?
Most people begin noticing meaningful improvement within four to six weeks of starting a gut-brain therapy program. In Nerva's randomized controlled trial, participants showed clinically significant improvements in managing both overall symptom severity and abdominal pain over the course of the 6-week program.¹¹
