Continuous Glucose Monitors or CGMs are one of our favorite methods for screening for Gestational Diabetes in pregnancy. So, what is a CGM? It is a wearable medical device that tracks blood sugar (glucose) levels in real time 24/7, providing data on trends & current levels through a small sensor inserted under the skin. It is a great way for us to look at your diet & how it is impacting your body during pregnancy. Of course, there is always a time & place for glucose testing at the lab, but for many, having access to CGMs is an appropriate alternative.
Gestational Diabetes can impact anyone, yes, even our healthiest parents. There are definitely risk factors that can up your likelihood of developing Gestational Diabetes in pregnancy, but even someone with no risk factors can develop it. Some of the risk factors include; a family history of diabetes, being over 25yo, obesity, history or current eating disorders, PCOS, & some races & ethnicities.
Gestational diabetes can, in most cases, be treated through diet and lifestyle changes. Occasionally a medication is needed to help control it, but in 70-85% of cases, diet/lifestyle will do the trick! Sometimes the idea that diet can help with Gestational Diabetes makes people think that it is similar to type two diabetes. But unlike type two diabetes, Gestational Diabetes isn’t caused by lifestyle, it is actually primarily caused by pregnancy hormones from the placenta that cause insulin resistance.
The good news is that by changing your lifestyle & diet & controlling your glucose levels, you are preventing complications in birth and postpartum, but also preventing your kiddo from developing diabetes later in life!
Our clients who treat their Gestational Diabetes report feeling grateful that they are learning to better take care of their body. As well as enjoying the CGM & what it is teaching them about how the food they are eating is interacting & impacting their bodies in real time. If we choose to listen & learn, the habits we learn in pregnancy might just be habits that change the outcome for the rest of our lives. Though screening is sometimes stigmatized, we love the reminder knowledge is power!
