Heightened Responses to Stressors in Patients with Inflammatory Bowel Disease (original) (raw)

2005, American Journal of Gastroenterology

Several studies suggest that stressful situations (stressors) worsen the course of inflammatory bowel disease (IBD), but the mechanism is not known.

To test this hypothesis, we determined whether stressor-induced activation of BGA is exaggerated in IBD patients.
