Gestational diabetes symptoms can be subtle or not show up at all, but watch out for things like feeling extra thirsty, needing to pee more than usual, feeling tired all the time, or having blurry vision. It’s important to get tested because untreated gestational diabetes can affect both you and your baby. Staying on top of it helps keep you both healthy!
Gestational diabetes mellitus (GDM)
Gestational diabetes mellitus, or GDM for short, is one of the most common conditions affecting pregnancy—and it’s on the rise.
GDM happens when your blood sugar levels become high during pregnancy, and you don’t have a history of diabetes. Though it can occur at any stage, it’s most common in the second and third trimester, and usually disappears after your baby is born.
If you’re diagnosed with gestational diabetes mellitus, it means your body is struggling to produce enough insulin—the hormone that helps regulate blood sugar levels.
So, instead of blood sugar (glucose) being moved to your cells where your body needs it for energy, it builds up in your blood, where it can cause complications for both mom and baby, including large birth weight, pre-term birth, and a risk of developing type 2 diabetes in later life.
Symptoms of gestational diabetes
Most pregnant women with GDM don’t experience any noticeable symptoms. However, if you have gestational diabetes symptoms from high blood sugar (hyperglycemia), you might notice some of the following signs:
- Needing to pee more often, especially at night
- Being more thirsty than usual
- Having a dry mouth (dehydration)
- Feeling tired and lacking energy
- Losing weight without trying
- Itchy vagina
- Blurred vision.
Contact your gynecologist if you’re worried that you’re at risk of or that you’re showing symptoms of gestational diabetes.
How to diagnose GDM: Gestational diabetes test
Doctors use blood tests to diagnose GDM. Routine screening usually takes place between 24-28 weeks of pregnancy, though you might be tested earlier if you’re at risk or are showing symptoms of gestational diabetes.
The most common diagnosis method is the oral glucose tolerance test (OGTT), which measures how your body responds to sugar.
