Highlights
Among parous women in the Hispanic Community Health Study/Study of Latinos, a history of gestational diabetes mellitus was associated years later with a distinct gut microbial profile, including enrichment of potentially proinflammatory taxa and depletion of short-chain fatty acid-producing species.
Fifteen serum metabolites tracked consistently with both prior gestational diabetes and the gestational diabetes-related microbiome; nine of these metabolites were also associated with glycaemic traits and incident type 2 diabetes.
