WHO is overhauling its guidelines on diabetes in pregnancy

The World Health Organization is updating its 2013 recommendations on diagnosing and classifying high blood sugar (hyperglycemia) during pregnancy — a condition that touches a staggering number of families worldwide. A Guideline Development Group (GDG) is convening October 20–24, 2026 to review the latest evidence and shape the new guidance, which is expected to be released later this year.

The update follows WHO's first-ever comprehensive care recommendations for pregnant women with diabetes, published in November 2025. New research has emerged on how best to screen, diagnose, and classify gestational hyperglycemia — particularly in low- and middle-income countries where undiagnosed pre-existing diabetes is common and resources are limited.

By the Numbers:

• 1 in 6 live births (≈21 million/year) is affected by hyperglycemia during pregnancy
• Associated risks include stillbirth, macrosomia, neonatal hypoglycemia, hypertensive disorders, and birth injury
• Most of the global diabetes burden falls on low- and middle-income countries

Why it matters: Accurate, up-to-date diagnostic criteria are essential for getting the right care to the right patients. Clearer global guidance could meaningfully reduce maternal and newborn complications — especially in under-resourced settings where the stakes are highest.
