Irritable Bowel Syndrome Message Boards | Re: Additional question to 'IBS"?

C or D are not necessary conditions for diagnosing IBS. Pain is likely a more significant indicator.

The ROME III diagnostic criteria for Function GI disorder defines IBS as follows:

C1. Irritable Bowel Syndrome Diagnostic criterion*

Recurrent abdominal pain or discomfort** at least 3 days/month in the last 3 months associated with two or more of the following:

1. Improvement with defecation
2. Onset associated with a change in frequency of stool
3. Onset associated with a change in form (appearance) of stool
* Criterion fulfilled for the last 3 months with symptom onset at least 6 months prior to diagnosis
** "Discomfort" means an uncomfortable sensation not described as pain.

In pathophysiology research and clinical trials, a pain/discomfort frequency of at least 2 days a week during screening evaluation is recommended for subject eligibility.

Stress is a well-known and recognised IBS trigger. For some people is can be a bigger trigger than foods.
