Continuous glucose monitoring (CGM) is gaining recognition as a vital technology for managing diabetes during pregnancy, with growing evidence that it can lead to healthier outcomes for both mothers and newborns. Medical experts emphasize that CGM offers real-time, detailed insights into blood sugar fluctuations, enabling more precise management of gestational diabetes and pre-existing diabetes in pregnant women.
Gestational diabetes mellitus (GDM) is one of the most common endocrine disorders in pregnancy, associated with increased risks such as pregnancy-related hypertension, preeclampsia, miscarriage, macrosomia (large birth weight), and neonatal hypoglycemia. Traditional self-monitoring methods, while helpful, often miss significant fluctuations in blood glucose that can impact pregnancy outcomes.
CGM devices, which continuously track glucose levels throughout the day and night, allow for better detection of dangerous highs and lows. This technology not only helps in maintaining blood glucose within a target range but also provides a crucial metric known as “time in range” (TIR). Studies indicate that a higher TIR during pregnancy is linked to improved gestational outcomes, reducing the likelihood of complications for both mother and child.
Recent research has shown that women who used CGM during pregnancy had better control over their blood sugar levels, resulting in fewer adverse outcomes such as preterm birth and the need for neonatal intensive care. For instance, a multinational randomized trial found that pregnant women with type 1 diabetes who used CGM experienced significantly better health outcomes for themselves and their babies, regardless of whether they managed their diabetes with insulin pumps or injections6.
Experts also highlight that CGM can help predict the development of gestational diabetes earlier in pregnancy by identifying abnormal glucose patterns before traditional diagnostic tests are conducted. Early intervention could be key to preventing complications and improving long-term health for both mother and child.
While CGM technology is more expensive than standard glucose testing, proponents argue that its potential to prevent costly complications could lead to overall healthcare savings in the long run.
“Continuous glucose monitoring can safely and effectively monitor blood glucose changes in patients with gestational hyperglycemia, thereby reducing adverse pregnancy outcomes,” note researchers in a recent review.
