  • bodily exam
  • symptom document
  • ruling out different situations

The Rome IV standards form is the premise for diagnosing IBS.

These criteria say a diagnosis may be made handiest after a person has had signs at least 1 day in keeping with the week over the past 3 months and having symptoms that started out at least 6 months ago.
