Staying Screened for Life
Reviewed by CDE Mehandi Sharma · Updated
A normal glucose test at your postpartum visit is genuinely good news. It is not a discharge from further testing.
Because the risk of developing Type 2 diabetes after GDM stays elevated for decades, testing needs to continue at intervals for the rest of your life — not once, and not only if you feel unwell.
In practice this means asking for a fasting glucose or HbA1c periodically, and asking sooner if you notice symptoms: unusual thirst, passing urine frequently, tiredness that rest does not fix, or blurred vision.
There are specific times to test rather than wait. Before trying to conceive again. If you gain significant weight. If you are diagnosed with PCOS or high blood pressure. And if a close relative develops Type 2 diabetes.
The practical obstacle is that nobody else is tracking this. Your obstetric care concludes, your baby has a paediatrician, and your own follow-up quietly has no owner. So you have to own it.
Two concrete things help. Put "gestational diabetes in [year]" into your permanent medical history and mention it to every new doctor you see, for the rest of your life — it changes what they should screen you for. And set a recurring reminder rather than trusting yourself to remember in three years.
Also worth knowing: your risk is largely modifiable, which makes reducing it more than a formality.
