[Psychological disorder associated to inflammatory bowel disease].

The symptomatology of patients with ulcerative colitis or Crohn's disease is not only characterised by bowel related symptoms. There is indeed psychological and psychiatric comorbidity. Depression and anxiety seem to be more common. These disorders could be etiologically related or appear as a consequence of the disease. At present, it seems unlikely that psychogenic disorders or major stressful life events play an important role in the origin of the disesses or in their severity, although there are however neuro-endocrine-immune interactions. Minor daily stressful life events are however important for the quality of life of patients with ulcerative colitis and Crohn's disease.
