Gut microbiome in gestational diabetes: a cross-sectional study of mothers and offspring 5 years postpartum.

These results suggest that there may be no discernible microbiome basis to GDM susceptibility in high-risk women, whereas microbiome differences between the offspring could be of greater biological significance. The heterogeneous nature of the disease could be obscuring potential differences between women. A longer time-series study, with carefully defined subject subgroups, may be an appropriate course of future investigation into GDM and the microbiome.
