What this trial studies

This project investigates the effectiveness of probiotics in improving gut microbiota and alleviating symptoms of functional constipation in adults aged 18 to 81. The study focuses on patients who experience difficulty in defecation and reduced bowel movement frequency, which significantly impacts their quality of life. Participants will be randomly assigned to receive either the probiotic treatment or a placebo, allowing for a comparison of outcomes. The study aims to provide insights into a potential non-pharmacological treatment option for this common condition.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 81 who meet the diagnostic criteria for functional constipation as per the Rome IV guidelines.

Not a fit: Patients with refractory constipation or those whose constipation is caused by neurological, metabolic, or obstructive diseases will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new, effective option for managing functional constipation without the need for laxatives.

How similar studies have performed: Previous studies have shown promising results with probiotics for gastrointestinal issues, suggesting potential success for this approach.
