Gestational Diabetes Mellitus (GDM) is a condition affecting blood sugar levels causing them to be elevated. It occurs in women during pregnancy, most commonly in the second trimester. These patients would have had normal blood sugar levels prior to the pregnancy.
- 12.4% of women in Brisbane are affected by GDM (higher risk in certain ethnicities).
- Women with GDM have a 7 times greater risk of developing type 2 diabetes in later life than women without GDM.
- An approximate 30% risk of a recurrence of their GDM in a subsequent pregnancy and up to 50% risk of developing Type 2 Diabetes within 10-20 years.
- Children born to mothers with GDM are at greater risk of obesity, metabolic syndrome, future GDM and type 2 diabetes than those born to unaffected mothers.
Complications of GDM:
- Large babies or what is referred to as Macrosomia which leads to:
- Increased risk of operative delivery: Caesarean and Instrumental such as forceps or suction vacuum.
- Shoulder dystocia: When the baby’s shoulders fail to deliver after the baby’s head. This is an emergency and can lead to further complications such as fractured baby bones and nerve damage.
- Preeclampsia: A disease occurring in pregnancy that leads to high blood pressure and can affect multiple organs in the mother. If untreated, it can lead to maternal seizures referred to as eclampsia.
- Intrauterine Fetal Demise: If the GDM is poorly controlled, it can lead to fetal death.
At Sunnybank Centre for Women, both Dr Nelson Gonzalez and Dr Joseph Jabbour have a wealth of experience in the management of GDM. The pregnancy will be closely monitored to achieve the best possible outcome.
