Objective:

To evaluate the effect of a 6-month probiotics supplementation on quality of life, bowel habits, excess weight loss, and changes in stool composition and fecal Calprotectin in severely obese patients undergoing various types of bariatric surgeries, including laparoscopic SG, RYGB, and others.

Key Findings:
  • Probiotic supplementation improved bowel health and quality of life in post-bariatric surgery patients, with statistically significant results.
  • Significant changes in stool composition and fecal Calprotectin levels were observed.
  • Weight loss outcomes were positively influenced by probiotic use.
Interpretation:

Probiotics may serve as a beneficial adjunct therapy for improving gastrointestinal health and quality of life in patients post-bariatric surgery.

Limitations:
  • Study limited to a specific population and surgical procedures, which may affect generalizability.
  • Short follow-up duration of 6 months may not capture long-term effects, potentially limiting the understanding of probiotics' efficacy.
Conclusion:

Probiotics can enhance bowel function and quality of life in severely obese patients following bariatric surgery, suggesting their potential role in postoperative care and warranting further investigation.
