Gestational diabetes is diabetes first diagnosed during pregnancy. It often has no obvious symptoms, which is why screening during pregnancy is important.
Quick summary
With treatment and follow-up, many people with gestational diabetes have healthy pregnancies. The plan usually includes glucose monitoring, food guidance, physical activity when safe, and sometimes medicine.
Key takeaways
- Screening often happens between 24 and 28 weeks, or earlier if risk is higher.
- Gestational diabetes can affect the parent and baby if glucose is not managed.
- Treatment may include meal planning, activity, glucose checks, insulin, metformin, or other medication when recommended.
- After pregnancy, follow-up matters because future type 2 diabetes risk is higher.
What care usually includes
- Prenatal visits and glucose targets set by the pregnancy care team.
- Nutrition guidance that supports pregnancy, not weight-loss dieting.
- Safe activity if approved by the obstetric clinician.
- Medication when lifestyle steps are not enough.
- Postpartum glucose testing and long-term diabetes prevention planning.
Important caveats
Do not try to lose weight during pregnancy unless your obstetric clinician gives a specific plan. Pregnancy nutrition should support the baby and the pregnant person.
If high blood sugar is found early in pregnancy, clinicians may evaluate whether diabetes was present before pregnancy. Follow-up after delivery helps identify ongoing risk.
Practical takeaway
Gestational diabetes is manageable, but it should not be ignored after delivery. Ask about postpartum testing and future diabetes prevention.

What to ask your care team
