Pregestational diabetes requires strict glycemic control during pregnancy.Continuous glucose monitoring (CGM) devices measure interstitial glucose levelswithout the need for capillary puncture. Four pregnant women with pregestationaltype 2 diabetes mellitus were studied with the aid of CGM during 2 weeks of theirgestation. They had weekly nutritional sessions and medical controls with anendocrinologist. The average glucose level ranged from 82 to 171 mg/dL. The CGMallowed early changes in the treatment of one patient with hypoglycemia. All patientsstated that the GCM helped them in their food selection. In conclusion, the GCMhelped in carbohydrate recognition and treatment readjustment. The CGM was wellaccepted for use.

Appropriate glycemic control during pregnancy prevents maternal-fetal complications. Continuous Glucose Monitoring (CGM) devices measure interstitial glucose levels, allowing patients and providers observe glucose values in real time. There are clear benefits of this tool, but lack of clinical experience in Peru. Three pregnant women with gestational diabetes were managed with the help of the CGM, along with nutritional education sessions and medical check-ups with an endocrinologist. All pregnant women had adequate glycemic control with the use of CGM. Two of them required insulin treatment and nutritional counseling, while the other only required nutritional management. The CGM was well received by the patients because it helped in the recognition and counting of carbohydrates, as well as in the adjustment of the treatment.
