Increased insulin resistance during pregnancy ultimately interferes with glycaemic control. Women will observe increasing insulin requirements to maintain euglycaemia and are likely to experience increasing hypoglycaemic episodes.
Reduced identification of these episodes—so-called ‘hypoglycaemia unawareness’—is common in pregnancy and can be dangerous to the mother.
Hypoglycaemia remains the leading cause of maternal deaths among diabetic women and it is therefore crucial for mothers to increase glucose monitoring and have regular specialist review.
