There is no specific diagnostic test for irritable bowel syndrome thus in order to diagnose irritable bowel syndrome; there are special criteria for this; which is known as Rome III criteria, based on the international meeting of the gastroenterologists in Rome.

Depending on the Rome III criteria, we can diagnose a patient with irritable bowel syndrome if his symptoms met the following points:

  • The patient is complaining from discomfort in the abdomen; not necessarily pain, at least one time every week during the last two months

The patient must have two of the following symptoms; in addition to previous point:

  • The abdominal discomfort is relived completely after passing stools
  • There is a history of diarrhea or constipation; increase or decrease in the number of bowel motions
  • There is a history of changes in the appearance of the stools

The effects of dietary changes on irritable bowel syndrome patients are not documented yet.

Adding more fibers to the diet may help in treating constipation rather than the whole syndrome. Some patients documented good outcome after adopting the healthy diet and doing exercises frequently so it is recommended for those patients to do so.

In addition, there is a separate medical entity known as small intestine bacterial overgrowth; which may share some symptoms with irritable bowel syndrome but it is totally different disease.
