Answer

The Rome IV criteria for the diagnosis of irritable bowel syndrome require that patients have had recurrent abdominal pain on average at least 1 day per week during the previous 3 months that is associated with 2 or more of the following [2] :

  • Related to defecation (may be increased or unchanged by defecation)

  • Associated with a change in stool frequency

  • Associated with a change in stool form or appearance

The Rome IV criteria (May 2016) only require abdominal pain in defining this condition; "discomfort" is no longer a requirement owing to its nonspecificity, and the recurrent abdominal pain. [2]

Supporting symptoms include the following:

  • Altered stool frequency

  • Altered stool form

  • Altered stool passage (straining and/or urgency)

  • Mucorrhea

  • Abdominal bloating or subjective distention
