Negatively perceived adulthood life events are associated with an increased risk for irritable bowel syndrome (IBS), worse symptom severity and quality of life, and a dysregulated stress response. This according to a study of >200 participants in which researchers studied 129 patients with IBS (mean age 28.1 years, 66% women), and 108 healthy individuals (controls; mean age 29.8 years, 60% women) who completed the Life Experiences Survey from August 2013 to September 2017. They found:
- Compared with controls, patients with IBS perceived more adulthood life events as negative and had a significantly higher negative life event impact score.
- In patients with IBS, the presence of more negatively perceived adulthood life events was associated with worse IBS symptom severity and IBS-related quality of life.
- Negatively perceived adulthood life events were associated with reduced production of adrenocorticotropic hormone (ACTH) in response to corticotrophin-releasing factor in those with IBS vs controls.
