Diabetes and Pregnancy Can a “normal” person also become diabetic in pregnancy?
Gestational Diabetes • Definition: Diabetes with onset or first recognition in pregnancy • Pregestational diabetes: Diabetes diagnosed before pregnancy, type I or II • Gestational diabetes : 87% of all diabetes in pregnancy
Who will get gestational diabetes? • It could happen to anybody
Should we screen and when? • YES!!! • Ideal world - between 24-28 weeks gestation • Glucose tolerance test – 75mg • In South Africa?
Selective screening : 10 factors • History of previous gestational diabetes • Certain ethnic groups • Older than 35 years • Weight more than 85 kg • First degree family history of DM • History of typical diabetic symptoms • Previous infant over 4kg • Previous stillbirth • Severe polihydramnios • Repeated glycosuria
What are the effects of diabetes on the pregnancy? • Antepartum: • Congenital abnormalities • Macrosomia • Intrauterine death • Polyhydramnios – preterm labour
What are the effects of diabetes on the pregnancy? • Delivery: • Shoulder dystocia • Erb’s palsy
What are the effects of diabetes on the pregnancy? • Postpartum: • Neonatal hypoglycaemia • Polycythaemia • Hyperbilirubinaemia • Respiratory distress syndrome
Biggest fear? • Unexplained intrauterine death • Fetal hyperglycaemia and hyperinsulinemia • Increased fetal oxygen consumption • Fetal hypoglycaemia and acidosis
Management • Confirm diagnosis • Ophthalmologist • Kidney function – 24 hour protein clearance • Blood pressure • Urine – MCS • First trimester screening and detailed anatomy sonar • TSH • HbA1C • Fetal monitoring
Treatment • Control known diabetic patients optimally before conception • Diet • Insulin – gold standard • Oral hypoglycaemic agents – more studies needed
Delivery : When? • Often preterm • Corticosteroids in hospital • Glucose abnormal up to 5 days • Multidisciplinary decision • Mom vs. fetus
Delivery : How? • The big debate • Caesarean section vs. normal vaginal delivery • All factors into consideration – macrosomal, timing, urgency, maternal choice . . .
Conclusion • We have to screen • Increasing problem world wide • We can improve outcome dramatically
