What happens if GCT is high in pregnancy?

A high GCT in pregnancy suggests possible gestational diabetes and requires a diagnostic oral glucose tolerance test and closer obstetric care. Management may include diet, exercise, blood-glucose monitoring and sometimes metformin or insulin. Untreated hyperglycaemia increases risks of large birth weight, preeclampsia, cesarean delivery and neonatal hypoglycaemia or jaundice, and raises long-term diabetes risk for mother and child.

How does GD affect my baby?

Gestational diabetes can make your baby grow larger than average (macrosomia), increasing risks of birth injuries and cesarean delivery. It also raises chances of preterm birth, neonatal low blood sugar, breathing difficulties, and, if uncontrolled, stillbirth. Long-term, exposed children have higher odds of obesity and type 2 diabetes. Good glucose control and medical monitoring significantly reduce these risks.

Glucose Challenge Test, GCT-(75gm glucose), in Lucknow

Q: What is the GCT glucose test?

The GCT (glucose challenge test) screens for gestational diabetes, usually at 24–28 weeks. You drink a 50 g glucose solution (non‑fasting) and have blood taken one hour later to measure glucose. If the result exceeds the screening threshold (commonly about 140 mg/dL or 7.8 mmol/L), a diagnostic oral glucose tolerance test is done to confirm.

Q: What is the 75g oral glucose challenge?

The 75 g oral glucose challenge (OGTT) is a diagnostic test to assess how your body handles sugar. After an overnight fast a baseline blood glucose is measured, you drink a 75 g glucose solution, and blood glucose is rechecked—commonly at 1 and 2 hours. Results help diagnose diabetes or gestational diabetes using established glucose thresholds.

Q: Is 75 grams of glucose normal?

Yes — a 75‑gram oral glucose load is the standard dose used in the adult oral glucose tolerance test (OGTT) to diagnose prediabetes and diabetes, not a recommended dietary amount. For adults, fasting plasma glucose <100 mg/dL is normal; 2‑hour post‑load <140 mg/dL is normal, 140–199 mg/dL indicates impaired glucose tolerance, and ≥200 mg/dL indicates diabetes. Discuss results with your clinician.
