The strongest available sources in this first pass are mixed biomedical and public-health sources, so conclusions should be framed as evidence-aware guidance rather than medical advice.

## Key Takeaways

- This page is generated only from sources stored in the Migaku evidence knowledge base.
- Current evidence mix: 1 narrative review, 1 preclinical study.
- Claims should be interpreted with the source type, study design, population, and publication date in mind.
- This article is educational and does not replace care from a qualified clinician.

## What The Sources Report

- Irritable bowel syndrome (IBS) is a chronic disorder of gut-brain interaction characterized by recurrent abdominal pain associated with altered bowel habits, in the absence of identifiable structural abnormalities. [Šuran Jelena (2026); evidence level 3]
- Early studies reported SIBO in up to 60-78% of IBS cases based on lactulose breath testing, though later investigations using more rigorous methods found lower prevalences (e.g., 4-20%). [Šuran Jelena (2026); evidence level 3]
- Functional constipation is predominantly characterized by impaired colonic propulsion and reduced stool hydration, often associated with delayed transit and diminished postprandial motor responses. [Ribichini Emanuela (2026); evidence level 4]
- Lembo, 2016 Sadeghi et al., 2023 Physiological and transit studies highlight the marked heterogeneity of CC, which may present with normal or delayed colonic transit and with different motor patterns, ranging from reduced propulsive activity to increased segmental tone. [Ribichini Emanuela (2026); evidence level 4]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation

For partially hydrolyzed guar gum constipation randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

## Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
