Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Guar, specifically guar gum, is utilized as a dietary fiber supplement to support or treat constipation in children. Guar gum is a water-soluble, fermentable fiber derived from the guar bean. Its use for pediatric constipation is supported by some scientific evidence, though the overall quality of studies and the strength of recommendations is moderate.

Several clinical trials and systematic reviews have investigated the efficacy of guar gum for promoting bowel regularity in children. Its mechanism involves increasing stool bulk and water content, thereby softening stools and stimulating peristalsis. A notable randomized controlled trial published in Acta Paediatrica (2001) demonstrated that partially hydrolyzed guar gum significantly improved stool frequency and consistency in children with functional constipation. Additionally, a 2012 review in the World Journal of Gastroenterology notes that guar gum, as a soluble fiber, can be effective in managing functional constipation in the pediatric population, though results are variable and dependent on dosage and individual tolerance.

Overall, guar gum is considered a safe and generally well-tolerated option for increasing dietary fiber in children with constipation. However, its use should be individualized, and excessive intake may cause gas or bloating. While not the first-line treatment, guar gum is recognized as a scientifically supported adjunctive therapy for constipation in children, meriting a moderate evidence rating.
