Other Functional Bowel Disorders
The following are other types of functional bowel disorders.
Often these other disorders are differentiated from IBS due to the lack of pain as a symptom.
Functional abdominal bloating/distension:Chronic feelings of bloating and/or visible distension occur.
However, abdominal bloating and/or distension must be the main symptom and other functional GI disorders should be excluded.
IBS with predominant diarrhea should be excluded.
Symptoms must have occurred for the last three months with onset at least six months prior to diagnosis.
But if you still have any questions about your diagnosis, ask your healthcare provider for clarification.
