Summary Background Maternal obesity and gestational weight gain ( GWG ) have a significant impact on the in utero environment, and thus on foetal development and the health of the offspring later in life. Objective The aim of this study was to determine the effect of maternal pre‐existing obesity and maternal GWG on glucose uptake from placentas from male and female offspring. Methods Total glucose uptake was measured in placental explants using radio‐labelled glucose. Results In the female placentas ( n = 36), GWG and glucose uptake were significantly negatively correlated ( r = −0.7, P < 0.0001; n = 36), and customized birthweight centile correlated with placental glucose uptake ( r = 0.36, P = 0.03) but not GWG . In the male placentas ( n = 45), GWG and glucose uptake were not related, and customized birthweight centile correlated with GWG ( r = 0.34, P = 0.02; n = 45), but not placental glucose uptake. Conclusions The female placenta can adapt glucose uptake in the face of excessive GWG . The male placenta showed no evidence of changing glucose uptake in response to maternal GWG .
