Background: Chronic constipation is common among children worldwide. Constipation includes functional constipation (FC) and organic constipation (OC). The early recognition of the causes of childhood constipation and its subsequent complications is important.
Purpose: This study aimed to evaluate the prevalence and causes of childhood constipation and compare the clinical characteristics, treatment, and outcomes of children with FC versus OC to identify the predictive factors.
Methods: This retrospective cross-sectional study analyzed children with FC or OC diagnosed in pediatric gastroenterology clinics, Salmaniya Medical Complex, Bahrain, 2017?2021. The Rome IV criteria were used to define FC.
Results: A total of 7,287 gastroenterology appointments were attended by 4,346 children during the study period. Of the 639 children (14.7%) with constipation, 616 (96.4%) were included in the study. Most patients had FC (n=511, 83%), whereas 17% (n=105) had OC. FC was more common in females than in males. Children with OC were younger (P<0.001) and had lower body weights (P<0.001), more stunted growth (P<0.001), and more associated diseases (P= 0.037) than those with FC. Enuresis was the most associated disease (n=21, 3.4%). Organic causes included neurological, allergic, endocrine, gastrointestinal, and genetic diseases. Allergies to cow milk protein were the most common (n=35, 5.7%). The presence of mucus in the stool was more common in OC than in FC (P=0.041), but no other symptoms or physical findings differed. A total of 587 patients (95.3%) received medication, among which lactulose was commonly prescribed (n=395, 64.1%). There were no intergroup differences in nationality, sex, body mass index, seasonal variation, laxative type, or treatment response. A good response was observed in 114 patients (90.5%).
Conclusion: Chronic constipation represented a significant proportion of outpatient gastroenterology visits. FC was the most common type. Young children with a low body weight, stunted growth, mucus in the stool, or associated diseases should be assessed for an underlying organic cause.
