Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In the present randomised double blind controlled study, the investigators will study the effects of oligosaccharides vs a placebo on the change in stool consistency and stool frequency in children with functional constipation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Functional constipation (FC) in children is a common gastrointestinal (GI) disorder with a worldwide prevalence ranging from 0.7% to 29.6%. Complaints include infrequent bowel movement, painful defecation due to hard and/or large stools, fecal incontinence, and abdominal pain. Although the condition is rarely life-threatening, it strongly impairs quality of life. Oligosaccharides have been shown to relieve constipation symptoms in young adults and elderly. However, sufficient evidence is lacking linking oligosaccharides intake to improve symptoms in children with FC. The investigators hypothesize that oligosaccharides might be able to relieve symptoms of constipation in young children as well, among which softening stools.
