In this study , we compared a marker of microvascular function , the permeability surface area for glucose ( PSglu ) , and forearm glucose uptake after an OGTT in obese women with impaired glucose metabolism and healthy lean nondiabetic women , with the aim to characterize whether decreased permeability surface area for glucose or decreased glucose uptake may contribute to postprandial hyperglycemia in the obese group .
