In Singapore, individuals with GDM are first advised to adopt diet modification, and if glycemic control is not on target despite diet control, insulin therapy is the next line of treatment. In all cases, patients need to perform self-monitoring of blood glucose (SMBG) to guide treatment decisions. These strategies aim to reduce the risks maternal and perinatal complications. In addition to that, preventing excessive gestational weight gain (GWG) is another important goal in women with GDM. This is because excessive GWG is not only associated with higher risks of delivering a large for gestational age infant, but is also the strongest risk factor for postpartum weight retention, and an important predictor for future development of Type 2 diabetes. Lifestyle intervention programs have been shown to be effective in reducing GWG in pregnant women.
