Treating Chronic Abdominal Pain in Patients with Chronic Abdominal Pain and/or Irritable Bowel Syndrome.

Irritable bowel syndrome (IBS) is probably the most common diagnosis in gastroenterology involving the brain-gut axis. By definition, pain is the most frequent symptom experienced by patients. It is important to understand the biopsychosocial and physiologic aspects of the disease when discussing treatment of IBS. Such therapies as lifestyle modifications, changes in diet, and cognitive behavioral therapy should be used in conjunction with pharmacotherapy rather than pharmacotherapy alone. The pathophysiologic mechanisms are reviewed in this article along with the current treatments available, in the era of growing demand for more effective treatments for the pain component of IBS.
