Aim and Context: The objective of this study was to evaluate the clinical profile and estimate the prevalence of functional gastrointestinal disorders (FGID) in children based on recent Rome IV criteria. Settings, Design, Methods and Materials: Using Rome IV diagnostic criteria, the questionnaire was prepared and a cross-sectional study was done on children attending pediatric department to assess the clinical profile of FGIDs in children under the age of 18. Statistical Analysis: Categorical data were analyzed using the Fisher’s exact test, and continuous data were analyzed using a two-sided t-test. Values of P < 0.05 were considered significant. Results: The results showed that 1448 children (40%) fulfilled the criteria for having at least one FGID. FGIDs were found in 47% of infants between 1-48 months, 28% between 4 and 11 years, and 42% between 11and18 years. Functional constipation (53%) was the most prevalent FGID in children under the age of four, followed by infantile regurgitation (18%) and infantile colic (15%), and although functional constipation was the most common FGID in children aged four to eighteen. However, in older children aged 4 to 18, functional abdominal pain disorders and functional defecation disorders are about equal in prevalence. When it comes to subtypes, functional constipation (15%) outnumbers irritable bowel syndrome (5.5%) and functional abdominal pain (5%). Conclusion: FGIDs are common in pediatric outpatient clinics. These disorders can be identified using the Rome IV criteria. Parental education and reassurance should be the first steps in managing FGIDs.
