[Pregnancy complicated by type I, type II and gestational diabetes: experiences from the diabetic-obstetric center of Białystock].

The aim of the study was the analysis of pregnancy outcome, newborn status, metabolic control and obstetric failure in 365 pregnant diabetic patients treated in Białystok Diabetic-Obstetric Center. Abortions occurred in 1.64% of pregnancies, intrauterine deaths--in 1.1%, and newborns deaths--in 2.47% cases. Macrosomia was observed in 14.8% of children (from 12% in type 1--up to 25% in gestational diabetes class G2). Congenital malformations were seen in 16 newborns of type 1 diabetic women (9.6%), 2 newborns of type 2 diabetics (22.2%), 6 children of mothers with gestational diabetes class G1 (4.2%) and 4 (8.3%)--class G2. The discussion underlines the role of a long duration of the disease as a key factor increasing the risk of complications and the importance of a good metabolic control before and shortly after conception.
