What this trial studies

This double-blind, randomized control trial aims to evaluate the effectiveness of a daily multi-strain symbiotic supplement on gut health in patients who have undergone weight loss surgery. Participants will provide stool samples before and three months after taking the supplement to assess changes in gut bacteria. Additionally, they will complete surveys regarding their bowel habits and gastrointestinal symptoms. The study addresses the gap in research regarding the impact of symbiotics on gut health following surgical alterations to the digestive system.

Who should consider this trial

Good fit: Ideal candidates are individuals who are at least 12 months post-malabsorptive weight loss surgery.

Not a fit: Patients who have undergone LapBand or intra-gastric balloon procedures may not benefit from this study due to the lack of significant surgical alteration to the gut.

Why it matters

Potential benefit: If successful, this study could improve gut health and reduce gastrointestinal distress in post-bariatric surgery patients.

How similar studies have performed: While there is limited research specifically on symbiotics in post-bariatric surgery patients, similar studies on probiotics and prebiotics have shown potential benefits in gut health.
