title: [Frecuency of functional gastrointestinal disorders and esophageal reflux disease in adults with non investigated dyspepsia in the Hospital Nacional Cayetano Heredia, Lima, Peru].
abstract: OBJECTIVE
  To assess the frequency of functional gastrointestinal disorders and gastroesophageal reflux disease in adults with uninvestigated dyspepsia in a general teaching hospital in Lima, Peru.
  
  
  METHODS
  Cross-sectional descriptive study performed at Hospital Nacional Cayetano Heredia Lima, Peru. Data was collected from questionnaires for Functional Gastrointestinal Disorders (FGID) based on Rome III criteria and from surveys for diagnosis of GERD applied to eligible patients who visited the gastroenterology unit from July to December 2011. Also, we collected the endoscopy's reports.
  
  
  RESULTS
  Among 110 patients who participated in the study, 70.9% were female and the mean age was 49.4 years (range 20-77, SD: ± 13.1). FGID was found in 82 subjects (74.6%) based on Rome III criteria. The most common FGID was functional dyspepsia (71.8%), followed by belching disorder (57.3%), nausea and vomiting disorder (27.3%) and irritable bowel syndrome (18.2%). Ninety-one patients (82.7%) were diagnosed of GERD, being the most common symptom regurgitation (80.0%). Structural abnormalities were found by upper endoscopy in 25 patients (22.7%).
  
  
  CONCLUSIONS
  We found a high frequency of GERD, belching disorder, nausea and vomiting disorder and irritable bowel syndrome among adult patients with uninvestigated dyspepsia. In addition, we found a high frequency of overlapping disorders in the same patient. Our results suggest the necessity to recognize the different types of FGID in order to avoid the under diagnosis of common conditions in the outpatient setting.
