The short explanation
Yes. Gestational diabetes usually goes away after the birth, but it raises your chance of developing type 2 diabetes later — often years later — and of gestational diabetes in a future pregnancy. That is why a blood sugar test is recommended some weeks after delivery, and then regular checks afterwards, commonly once a year. The follow-up test is one of the easiest things to miss with a new baby, so it is worth asking at discharge or at your postnatal check exactly when and where it will happen.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Which test is used, and when, varies between hospitals: some do a fasting sugar or glucose tolerance test around six to twelve weeks after birth, others an HbA1c a little later. Breastfeeding, regular movement and keeping weight in a healthy range all lower the later risk.
- If you plan another pregnancy, tell your clinician early about the gestational diabetes, because testing is usually done sooner the next time.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you which test is right for you, what your earlier readings mean, or how likely you are to develop diabetes. Those need your pregnancy records and a clinician who can see them.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- When should my first test after delivery be, and which test is it?
- How often should I be tested after that?
- What would you want me to do before another pregnancy?
- Is there anything that lowers my risk that fits with looking after a baby?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
- Get emergency care now (call 112 or 108) for vomiting with extreme thirst, fast breathing, confusion or unusual drowsiness.
- See a clinician within days for strong thirst, passing urine far more often, blurred vision or weight loss you cannot explain.
- Book a routine appointment if your post-delivery test was never done, even if it is now months or years later.
