Overview
- Published October 13 in the Journal of Human Nutrition & Dietetics and Neurogastroenterology & Motility, the guideline issues 59 statements developed using GRADE ratings and a Delphi consensus.
- Recommendations highlight psyllium (at least 10 g daily), magnesium oxide (0.5–1.5 g daily), kiwifruit (2–3 daily for at least 4 weeks), rye bread (6–8 slices daily for at least 3 weeks), and high‑mineral water (0.5–1.5 L daily).
- Probiotic supplements show modest benefits that vary by strain, with no single strain endorsed across all outcomes and a suggested trial period of at least four weeks.
- Whole‑diet approaches, including generic high‑fiber diets, lacked sufficient randomized evidence for recommendation, reflecting a major research gap.
- Most statements are based on low or very low certainty evidence, yet some are strong due to favorable benefit‑risk, affordability, and feasibility for adults with chronic idiopathic constipation who may still need clinical evaluation if symptoms persist.
