What this trial studies

This clinical study investigates the effects of resistant starch on patients suffering from constipation, a common gastrointestinal disorder affecting a significant portion of the adult population. The study aims to explore how resistant starch can enhance gut microbiota and alleviate constipation symptoms without the adverse effects associated with traditional laxatives. Participants will consume resistant starch to assess its impact on their bowel movements and overall gastrointestinal health. The research is grounded in the understanding that diet plays a crucial role in gut health and microbiome composition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults diagnosed with constipation according to the Roman IV criteria.

Not a fit: Patients with a history of colorectal tumors within the past two years will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safe and effective dietary alternative for managing constipation.

How similar studies have performed: Other studies have shown promising results with dietary interventions targeting gut microbiota, suggesting potential success for this approach.
