Daily Summary
GDM Outcomes & Risk Information
🤰
Maternal Outcomes
- • Pre-eclampsia risk: 2–4× increased
- • Caesarean section: ~40–60% vs 25–30% general
- • Postpartum T2DM risk: 50–70% within 10 years
- • Recurrent GDM next pregnancy: 30–84%
- • Cardiovascular disease risk elevated long-term
- • Postpartum depression association reported
👶
Neonatal Outcomes
- • Macrosomia (>4kg): 15–45%
- • Neonatal hypoglycaemia: 5–15%
- • Birth injury / shoulder dystocia risk elevated
- • Respiratory distress syndrome risk
- • NICU admission: 2–5× more likely
- • Child obesity & T2DM risk increased
🏃♀️
Lifestyle Interventions
- • MNT (Medical Nutrition Therapy): ~80% achieve targets
- • 30 min moderate exercise 5×/week
- • Low GI diet reduces glucose excursions
- • Metformin: effective 2nd-line option
- • Insulin if glucose targets not met
- • Postpartum screening at 6–12 weeks essential
📅
Screening Timeline
- • First trimester: Screen high-risk women at booking
- • 24–28 weeks: Universal OGTT screening
- • 28–32 weeks: Re-screen if initially negative + high risk
- • Postpartum 6–12 weeks: 75g 2hr OGTT
- • Annually thereafter: FBG or HbA1c

Diagnostic Criteria Summary
| Org | Fasting | 1hr | 2hr |
|---|---|---|---|
| IADPSG | ≥5.1 | ≥10.0 | ≥8.5 |
| WHO 2013 | ≥5.1 | — | ≥8.5 |
| ADA (CC) | ≥5.3 | ≥10.0 | ≥8.6 |
| NDDG | ≥5.8 | ≥10.6 | ≥9.2 |
All values in mmol/L. 1 positive value sufficient for IADPSG; 2 required for CC/NDDG.
