Fecal microbiota transplantation is being studied in the context of metabolic health, beyond its use for recurrent Clostridioides difficile infection. A new proof-of-principle study reveals that supplementing low-fermentable fiber following fecal microbiota transplantation may improve insulin sensitivity in individuals with severe obesity.

The microbiota of infants born by caesarean section resembles that of maternal oral cavity and skin, whereas that of vaginally born infants resembles that of the maternal gut microbiome. A new proof-of-concept study shows that the gut microbiota of C-section-born infants can be restored after delivery via orally administered maternal fecal microbiota transplantation.
