Psychological stress and disease activity in ulcerative colitis: a multidimensional cross-sectional study.

Abstract

Life stress is associated with both objective and subjective aspects of activity in ulcerative colitis. Although the association of life events with reported symptoms may be subject to recall bias, the association of perceived stress with rectal mucosal abnormalities in asymptomatic patients is strongly suggestive of a true link between psychological factors and ulcerative colitis activity.
