Can partially hydrolyzed guar gum be an alternative to lactulose in treatment of childhood constipation?



Can partially hydrolyzed guar gum be an alternative to lactulose in treatment of childhood constipation?



Turkish Journal of Gastroenterology 21(4): 360-364



In the present study, we aimed to investigate if partially hydrolyzed guar gum (PHGG) can be used safely as a fiber source for treatment of constipation in children and to compare its success with the most commonly used osmotic laxative, lactulose. A randomized prospective controlled study on 61 patients (partially hydrolyzed guar gum group, n: 31; lactulose group, n: 30) was performed. Patients were given lactulose or partially hydrolyzed guar gum for four weeks. Using a standardized bowel diary, defecation frequency, stool consistency, and presence of flatulence and abdominal pain were recorded. Family questionnaires about the success, safety and side effect profile of both treatment arms were also obtained. No significant differences were found in the baseline daily fiber (fruits and vegetables) intake between the two groups. Bowel movement frequency per week and stool consistency improved significantly in both treatment groups (p<0.05). The percent of children with abdominal pain and stool withholding also decreased eminently in both groups (p<0.05). Weekly defecation frequency increased from 4±0.7 to 6±1.06 and from 4±0.7 to 5±1.7 in the lactulose and partially hydrolyzed guar gum treated groups, respectively (p<0.05). According to the family questionnaire, the parents complained of bad taste, flatulence and necessity to ingest a high amount of drug in the lactulose treatment group. In the partially hydrolyzed guar gum treatment group, parents were satisfied with the defecation frequency of their children. Treatment with partially hydrolyzed guar gum is as effective as lactulose treatment in relieving stool withholding and constipation-associated abdominal pain, and its use improves stool consistency. Lactulose seemed to have more side effects, including flatulence and sensation of bad taste.
