Functional dyspepsia versus other functional gastrointestinal disorders: a practical approach in Belgian general practices.

This paper identifies the symptom profile associated with the four main diagnoses of functional digestive disorders (dyspepsia, gastro-oesophageal reflux disease (GORD), gastritis, and constipation) made by general practitioners in Belgium. Results are also presented from a multicentre study in which the effects of cisapride, administered as an oral tablet or suspension, were evaluated in patients with these functional digestive disorders. Analysis of symptom patterns revealed that early satiety and postprandial abdominal bloating were the most prominent symptoms, followed by eructation (belching), heartburn, regurgitation, postprandial epigastric burning or discomfort, and nausea. These symptoms occurred in all diagnostic groups. However, different symptom patterns were associated with each of the disorders; for example, heartburn and regurgitation were the core symptoms in patients diagnosed as having GORD, early satiety and abdominal bloating were characteristic of patients diagnosed with dyspepsia, and fasting or postprandial pain were characteristic of patients given the diagnosis of gastritis. Therefore, it appears that these diagnoses used by general practitioners in Belgium closely correspond to reflux-like, dysmotility-like and ulcer-like dyspepsia, as defined by an international working party. Cisapride improved the core symptoms in about 80% of patients with GORD or dyspepsia, relieved all epigastric symptoms in about 80% of patients with gastritis, and significantly decreased the use of laxatives and increased stool frequency in constipated patients. Cisapride was well tolerated and thus appears to be a useful option in the treatment of functional digestive disorders in a general practice setting.
