Diagnosis
of gestational diabetes Gestational diabetes is a condition that occurs when a pregnant woman has abnormally high blood sugar (glucose) levels during the second and third trimester of pregnancy. It is estimated that around 4-10% of pregnant women may develop this condition. Diagnosis of gestational diabetes can be done with a Glucose Challenge Test (GCT) or a Glucose Tolerance Test (GTT). During the GCT, a glucose solution is consumed and a woman’s blood sugar levels are monitored over time. If the test results are high, a woman will then need to complete the GTT. In the GTT, a woman consumes a two-hour glucose solution and blood samples are taken to measure glucose levels. If the levels exceed a certain threshold, a diagnosis of gestational diabetes is confirmed. Gestational diabetes can be a serious condition for both a pregnant woman and her baby. It increases the risk of preterm birth, pregnancy-induced hypertension, preeclampsia and macrosomia (large for gestational age babies). It is important for pregnant women to be tested for gestational diabetes to ensure that the pregnancy is monitored and managed effectively. Early diagnosis and treatment is key to ensure a healthy pregnancy.
