The Impact of Telemedicine during the COVID-19 Pandemic on Diabetes Management and Pregnancy Outcomes in Women with Gestational Diabetes Mellitus (GDM)

<b>Background/Objectives</b>: Gestational diabetes mellitus (GDM) can lead to various complications for both the mother and the child. Many factors influence the onset of the disease including GDM in a previous pregnancy, overweight and obesity, as well as the increasing age of women who become pregnant. The aim of this study was to assess the impact of telemedicine during the COVID-19 pandemic on diabetes management and pregnancy outcomes in women with gestational diabetes mellitus (GDM). <b>Methods:</b> A retrospective analysis was conducted. We compared two groups of GDM women from the pandemic and pre-pandemic periods in terms of pregnancy course and obstetric outcomes. <b>Results:</b> It was observed that women with GDM in the pandemic group were significantly more often overweight and significantly less often obese before pregnancy than women in the pre-pandemic group. GDM was diagnosed significantly earlier but in later pregnancies in the pandemic group than in the pre-pandemic group. The course of pregnancy in both groups was similar and the percentage of pregnancies with the delivery of neonates > 4000 g did not differ significantly. The number of caesarean sections and spontaneous deliveries was also similar in both periods. No differences were found in anthropometric parameters in newborns and neonatal and maternal complications. <b>Conclusions:</b> The occurrence of the COVID-19 pandemic and the necessity of employing telemedicine tools in the medical care of women with GDM did not significantly impact diabetes management and the pregnancy outcomes achieved.
