Interdisciplinary team work and recommendations of diabetologist and obstetrician is the condition of success of antenatal care and consequently perinatal outcome in pregnancy complicated by diabetes. Careful insight into the metabolic, haemodynamic and vascular disturbances is the basic of contemporary surveillance in diabetic pregnancy. The authors emphasise that a diabetic pregnant woman must not only pay attention to adequate nutrition and balanced exercise, but also be aware of and cope with characteristic, momentary swings in glycemia in order to overcome them by appropriate insulin therapy. Continuous supervision for several other complications associated with diabetic pregnancy, viz. hypertension, retinopathy, thyroid dysfunction, nephropathy and the threat of in utero foetal death is justified. Briefly, rigorous measures to sustain normoglycemia and normal blood pressure, examination of the retina, thyroid and renal functions as well as foetal status evaluation are paramount in appropriate management of major common diabetic complications in pregnancy.
