Blood glucose monitoring is an important strategy for managing gestational diabetes, but there is uncertainty about which methods are best, according to a Cochrane review of 11 trials involving nearly 1,300 individuals. Based on low- or very low-quality evidence, there were no clear differences for:

• Pre-eclampsia or hypertension, cesarean section, or induction of labor in women receiving care via telemedicine vs standard care.
• Their babies being born large-for-gestational age, developing a serious morbidity, or having hypoglycemia.
• Pre-eclampsia or cesarean section in women who self-monitored glucose levels vs those who received periodic glucose monitoring.
• Their babies dying, being born large-for-gestational age, or developing hypoglycemia.
• Pre-eclampsia, cesarean section, or perineal trauma in women who underwent postprandial vs preprandial glucose monitoring.

Babies born to women who had postprandial glucose monitoring were less likely to be born large-for-gestational age.
