Reduced adaptation of the pancreatic B cells during pregnancy is the major causal factor for gestational diabetes: Current knowledge and metabolic effects on the offspring

This commentary summarizes current knowledge on the pathophysiology of gestational diabetes, focusing on the role of the endocrine pancreas and the beta-cells, their adaptation in normal pregnancy, and recent insights in the molecular basis for deficient adaptation in diabetes occurring during pregnancy. Additionally, the effects of disturbed maternal glucose metabolism during pregnancy on the glucose metabolism of the offspring are discussed.
