Supplementation with Lactobacillus probiotics after Roux-en-Y gastric bypass increases weight loss and reduces bacterial overgrowth compared to placebo.

If you have had Roux-en-Y gastric bypass, taking Lactobacillus probiotics may help you lose more weight and reduce bacterial overgrowth compared to not taking them. This is a specific benefit for surgical patients, not necessarily for the general population. Discuss probiotic supplementation with your surgeon.

Our group showed that, in post-RYGB patients, supplementation with lactobacillus probiotics (phylum Firmicutes) led to greater weight loss and less bacterial overgrowth (as measured by the hydrogen breath test) than in RYGB patients given placebo.
