Managing irritable bowel syndrome.

IBS is a functional gastrointestinal disorder in which the patient has chronic or recurrent gastrointestinal symptoms (diarrhea, constipation or abdominal pain and bloating) that are unexplained by any structural or biochemical abnormalities. Research has demonstrated no causal relationship between psychosocial factors and the development of IBS. IBS cannot be diagnosed through radiologic, endoscopic or laboratory studies because the symptoms are not explained by structural or chemical abnormalities. One of the most important components of treatment is the development of an effective provider patient relationship. Behavioral treatments may be helpful in select patients. Dietary management can also reduce symptoms if the patient can identify foods that trigger them.
