What happened
WHO announced that a guideline development group will meet from 20 to 24 October 2026 to review evidence on screening, diagnosing and classifying hyperglycaemia in pregnancy, including gestational diabetes and pre-existing diabetes first recognized during pregnancy.
Why it matters
WHO says one in six live births is affected by hyperglycaemia in pregnancy. Diagnostic thresholds and classification shape who is identified, treated and followed after birth, so global guidance must work across high-resource and lower-resource settings.
What to watch
Final recommendations, conflict-of-interest handling, feasibility in lower-resource settings, postpartum follow-up pathways and the balance between underdiagnosis and overdiagnosis.
