In this blog, we’ll break down everything you need to know about the glucose test during pregnancy, why it’s important, and what to expect.
What is a Glucose Test?
A glucose test, also known as a glucose screening test or oral glucose tolerance test (OGTT), measures how your body processes sugar (glucose) during pregnancy. This test checks for gestational diabetes, a condition that can develop in pregnant women when their bodies don’t produce enough insulin to manage blood sugar levels effectively.
Gestational diabetes is common and can occur in any pregnancy, even if you’ve never had diabetes before. Detecting and managing it early is key to preventing complications for both the mother and baby.
Why is the Glucose Test Important?
The glucose test is important because gestational diabetes can affect both you and your baby. If untreated, it could result in:
- Excessive birth weight: Babies born to mothers with high blood sugar can grow larger than average, which may complicate delivery.
- Preterm birth: High glucose levels can increase the chances of preterm labor and delivery.
- Low blood sugar in newborns: Babies may experience hypoglycemia (low blood sugar) after birth.
- Type 2 Diabetes Risk: Women who have gestational diabetes are more likely to get Type 2 diabetes in the future.
By detecting gestational diabetes early through the glucose test, healthcare providers can recommend diet changes, exercise, or medication to keep your blood sugar levels in check.
When is the Glucose Test Done?
Usually, the glucose test is conducted between weeks 24 and 28 of pregnancy. However, if you’re at a higher risk of developing gestational diabetes—such as having a family history of diabetes, being overweight, or having a previous pregnancy with gestational diabetes—your doctor may recommend testing earlier in pregnancy.
