Post-partum plasma C-peptide and ghrelin concentrations are predictive of type 2 diabetes in women with previous gestational diabetes mellitus

Abstract

Background: Women with previous gestational diabetes mellitus (pGDM) are at increased risk of developing type 2 diabetes later in life. The aim of this study was to determine if circulating levels of metabolic hormones 12 weeks following a GDM pregnancy are associated with an increased risk of type 2 diabetes 8-10 years later. Methods: Fasting plasma concentrations of glucose, insulin, C-peptide, ghrelin, GIP, GLP-1, glucagon, leptin, PAI-1, resistin and visfatin were measured in 98 normal glucose tolerant women, 12 weeks following an index GDM pregnancy. Women were assessed every 2 years for up to 10 years for development of overt type 2 diabetes. Results: After a median follow-up period of..
