Limitations
T2D
REMISSION
We acknowledge several limitations of this study. Sample size limitations can have influenced the statistical power to detect changes in T2D remission after surgery. Moreover, we were unable to study the composition of the diet followed by the participants after surgery, which may affect the results. We have also observed a high interindividual variation in gut microbial composition, which makes the analysis between metabolic variables and microbiome difficult. We are aware of the absence of causality in the findings described in our study. For these reasons, this study should be considered as a hypothesis generator. Further studies should therefore be conducted to better understand the changes after BS, especially in microbiota composition, and its association with metabolic outcomes.
