The following factors increase the risk of developing gestational diabetes during pregnancy:
Many women who develop gestational diabetes have no known risk factors.
How Is Gestational Diabetes Diagnosed?
High risk women should be screened for gestational diabetes as early as possible during their pregnancies. All other women will be screened between the 24th and 28th week of pregnancy.
To screen for gestational diabetes, you will take a test called the oral glucose tolerance test. This test involves quickly drinking a sweetened liquid, which contains 50g of sugar. The body absorbs this sugar rapidly, causing blood sugar levels to rise within 30-60 minutes. A blood sample will be taken from a vein in your arm 1 hour after drinking the solution. The blood test measures how the sugar solution was metabolized (processed by the body).
A blood sugar level greater than or equal to 140mg/dL is recognized as abnormal. If your results are abnormal based on the oral glucose tolerance test, another test will be given after fasting for several hours.
In women at high risk of developing gestational diabetes, a normal screening test result is followed up with another screening test at 24-28 weeks for confirmation of the diagnosis.
