What this trial studies

This clinical trial evaluates the effectiveness of ABKefir, a probiotic, in alleviating symptoms of functional constipation in adults. A total of 165 participants will be randomly assigned to receive either a placebo, a low dose, or a high dose of ABKefir for 8 weeks. The study includes assessments of defecation patterns, anthropometric measurements, and biological samples at the start, mid-point, and end of the trial. The goal is to determine if probiotics can improve bowel function in individuals suffering from functional constipation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 who meet the Rome IV criteria for functional constipation.

Not a fit: Patients with serious underlying health conditions or those on medications that affect bowel function may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new, effective treatment option for adults suffering from functional constipation.

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