Distinct Metabolomic Profile Because of Gestational Diabetes and its Treatment Mode in Women with Overweight and Obesity

Abstract

<h3>Objective</h3><p>Whether the presence of gestational diabetes (GDM) and its treatment mode influence the serum metabolic profile in women with overweight or obesity was studied.</p><h3>Methods</h3><p>The serum metabolic profiles of 352 women with overweight or obesity participating in a mother‐infant clinical study were analyzed with a targeted NMR approach (at 35.1 median gestational weeks). GDM was diagnosed with a 2‐hour 75‐g oral glucose tolerance test.</p><h3>Results</h3><p>The metabolomic profile of the women with GDM (<i>n</i> = 100) deviated from that of women without GDM (<i>n</i> = 252). Differences were seen in 70 lipid variables, particularly higher concentrations of very low‐density lipoprotein particles and serum triglycerides were related to GDM. Furthermore, levels of branched‐chain amino acids and glycoprotein acetylation, a marker of low‐grade inflammation, were higher in women with GDM. Compared with women with GDM treated with diet only, the women treated with medication (<i>n</i> = 19) had higher concentrations of severalizes of VLDL particles and their components, leucine, and isoleucine, as well as glycoprotein acetylation.</p><h3>Conclusions</h3><p>A clearly distinct metabolic profile was detected in GDM, which deviated even more if the patient was receiving medical treatment. This suggests a need for more intense follow‐up and therapy for women with GDM during pregnancy and postpartum to reduce their long‐term adverse health risks.</p>
