Functional symptoms occur in inflammatory bowel disease probably more than in the general population. Existing disease indices rely heavily on symptoms that may be organic or functional. This may explain inconsistencies between recent therapeutic trials in inflammatory bowel disease. Clinically, misinterpretation can lead to over-treatment of functional symptoms with potent agents, and to under-treatment of inflammatory bowel disease when inflammatory features are more subtle.
