Abstract
A meta-analysis of randomized controlled trials suggests dietary fiber may be effective for treating functional constipation.
- Dietary fiber is recognized as a first-line treatment for functional constipation.
- The mechanism by which fiber alleviates constipation is not fully understood.
- Emerging evidence indicates that modulation of the gut-brain axis could play a role in fiber's effects.
- The analysis evaluated both the clinical efficacy of fiber and its impact on gut-brain axis biomarkers.
