Anxiety and depression: a common feature of health care seeking patients with irritable bowel syndrome and food allergy.

Abstract

A higher prevalence of state anxiety found in patients complaining of bowel symptoms could be linked to the presence of chronic ill status. The higher presence of trait anxiety and depression in IBS and FA patients could be responsible for an increase in the activity of the autonomic nervous system and could provoke motility alterations through mast cell mediator release as well as enhancing release due to allergen crosslinking with IgE at the mast cell surface. However, it is debatable whether psychological findings are characteristic of all IBS or FA patients, or just represent the subset that see physicians.
