A friend aged in her early 40’s recently recounted her experience in hospital after having her first child. Like most women, she had gained weight during her pregnancy, placing her pre-delivery weight at around 95 kg. One of the nurses working on the maternity ward came into the room my friend shared with several other mothers and their newborns. The nurse was looking for a woman who had gestational diabetes. My friend explained that the nurse looked around the room and then came straight over to her bed and asked, ‘Are you the woman with gestational diabetes?’ She was not. It was the younger (mid 20s) and physically much smaller woman in the bed across the room.
