Key takeaways
- Stress can worsen symptoms of irritable bowel syndrome (IBS) without being the underlying cause.
- The American College of Gastroenterology suggests gut-directed psychotherapy for IBS symptoms.
- Persistent or alarming digestive symptoms need medical evaluation.
The gut–brain connection
Nerves and hormones link the digestive tract and the brain, so emotional strain can change gut movement and sensitivity. Stress does not cause IBS, but it can trigger flares.
What research supports
The American College of Gastroenterology's guideline suggests gut-directed psychotherapy, including cognitive-behavioral therapy and gut-directed hypnotherapy, for global IBS symptoms.[1] (source 1) A network meta-analysis found that several psychological therapies were effective, with gut-directed hypnotherapy and CBT among the best supported.[2] (source 2)
Practical steps
- See a clinician to confirm the diagnosis and rule out other conditions
- Keep a food and symptom diary
- Practise a daily relaxation technique
- Ask about CBT or gut-directed hypnotherapy
