Abstract:
Fibromyalgia, chronic fatigue syndrome, and interstitial cystitis frequently overlap with irritable bowel syndrome (IBS). There is a positive correlation between the incidence of these comorbidities and increased health care seeking, reduction in quality of life, and higher levels of mood disorders, which raises the question of a common underlying pathophysiology. A possible central hypersensitization disorder seems to be particularly involved in the dysfunction of bidirectional neural pathways and viscerovisceral cross-interactions within the CNS, thus explaining these many extraintestinal manifestations in IBS.
