Description
Why It’s Done:
This test is commonly recommended:
• To diagnose gestational diabetes, especially between the 24th and 28th week of pregnancy.
• To evaluate glucose metabolism in pregnant women who are at higher risk of developing diabetes (e.g., those with obesity, family history of diabetes, or previous GDM).
• To prevent pregnancy-related complications, such as high birth weight, premature delivery, or preeclampsia.
• To protect long-term health of both mother and baby by identifying and managing abnormal blood sugar early.
This 75-gram OGTT follows the WHO and IADPSG guidelines for gestational diabetes screening.
Preparation:
Proper preparation helps ensure accurate results:
1. Fasting Required:
o You must fast for 8–10 hours before the test.
o Water is allowed during fasting.
2. Healthy Diet:
o Eat a balanced diet including carbohydrates for at least 3 days prior to the test unless advised otherwise.
3. Medication:
o Inform your healthcare provider about all medications you are taking. Some may interfere with blood sugar results.
4. Avoid Strenuous Activity:
o Do not exercise heavily before the test, as it may affect glucose metabolism.
5. Time Needed:
o The test takes around 2.5 to 3 hours, so plan accordingly and bring reading material or other comfort items
