Abstract
Background: Functional constipation and gastroesophageal reflux disease (GERD) are two common childhood digestive disorders which can cause a lot of complications among them if untreated. Since an overlap and relationship between functional gastrointestinal disorders have been shown in some studies, so present study was performed to investigate the frequency of functional constipation among children with reflux in compare with children without reflux.
Methods: A cross-sectional study was conducted on all children who referred to digestive diseases clinic of Ali-Asghar Hospital in Tehran, Iran, from April 2008 to January 2010. Patients that referred for follow up were excluded from study and a total of 474 children were included in this study. A questionnaire including symptoms of reflux and functional constipation was completed for all subjects by design’s executer after parental consent. Other data related to history, physical examination and results of paraclinic investigations for functional constipation diagnosis were also collected.
Results: In general 247 children (52%) were male and 227 children (48%) were female. Nineteen children (4%) had gastroesophageal reflux disease in this study which 6 of them (31.5%) were less than 1 year old and 13 of them (68.5%) were greater than 1 year old. Opisthotonic posturing, abdominal pain, heartburn and recurrent vomiting were the most common symptoms in children with reflux. There was also functional constipation in 60 children. Twelve patients (63.2%) had functional constipation among 19 children with reflux, whereas 48 patients (10.5%) had functional constipation among 455 children without reflux. This different frequency ranges of functional constipation among children with and without gastroesophageal reflux was statistically significant (P= 0.001).
Conclusion: The frequency of functional constipation in children with gastroesophageal reflux was significantly more than normal children. Further studies are recommended to investigate the relationship between functional constipation and gastroesophageal reflux in children.
