ಗ್ಲೂಕೋಸ್ ಟಾಲರೆನ್ಸ್ ಟೆಸ್ಟ್ (OGTT)

What is the difference between the DIPSI test and the standard OGTT?

The DIPSI (Diabetes in Pregnancy Study group India) method is a simplified, non-fasting single-point test: you arrive without fasting, drink 75g of glucose in water, and give one blood sample at 2 hours. A result ≥ 140 mg/dL diagnoses GDM. It is practical for busy antenatal clinics. The WHO/IADPSG OGTT requires overnight fasting and three blood samples (fasting, 1-hour, 2-hour). Both are valid — your doctor will choose based on your clinic's protocol.

Do I need to fast before the glucose test?

It depends on which method your clinic uses. For the DIPSI method: no fasting required. For the WHO OGTT: yes — you must fast for 8–10 hours (usually overnight) before the test. Ask your doctor or the laboratory specifically which test they are using and whether to fast.

My GDM test was positive. What happens now?

A positive OGTT means GDM is diagnosed. You will be referred to a dietitian or given a medical nutrition therapy (MNT) plan — the cornerstone of GDM management. Blood sugar monitoring at home (fasting and post-meal) is started. If diet alone does not achieve target blood sugars within 1–2 weeks, medication (usually metformin or insulin) is added. GDM requires more frequent antenatal visits, fetal growth scans, and careful delivery planning.

Does gestational diabetes mean I will have diabetes forever?

GDM usually resolves after delivery — blood sugar typically returns to normal within 6 weeks postpartum. However, it is a strong warning signal: women with GDM have a 50% lifetime risk of developing Type 2 diabetes. A fasting blood sugar or HbA1c is recommended at 6 weeks postpartum to confirm resolution, and annual screening thereafter. Lifestyle changes (healthy weight, regular exercise, reduced refined carbohydrates) significantly reduce the conversion to T2DM.

Does one abnormal value mean I have GDM?

Yes. According to the current DIPSI and International guidelines, even a single value meeting or exceeding the threshold is enough to diagnose Gestational Diabetes. Early diagnosis is key to a healthy outcome.

Is insulin safe during pregnancy?

Yes. Insulin is the safest medication for controlling blood sugar in pregnancy. It does not cross the placenta and has been used safely in pregnant women for decades. If your doctor recommends insulin, it means your blood sugars need tighter control than diet and oral medications can achieve. Starting insulin is not a sign of failure — it is the right treatment to protect your baby.
