Our findings are consistent with a targeted mass spectrometry metabolome undertaken 6–8 weeks postpartum in a cohort of individuals with normoglycaemia but with previous GDM, where lactation intensity was associated with lower triglycerides (and diglycerides) and higher phospholipids [36]; indeed they suggest that downregulation of triglycerides/diglyceride lipogenesis during lactation is directly associated with formation of phospho- and sphingolipids through the CEPT1 gene. This evidence concerns the gene CEPT1 and gestational diabetes.
