Doctors recommend that pregnant women be screened for gestational diabetes during the 24th to the 28th weeks of pregnancy, when the disease is most likely to occur. In some cases, Type 1 diabetes or Type 2 diabetes is revealed during pregnancy, which makes it hard to definitely differentiate from gestational diabetes.

Occasionally there will be symptoms of high blood sugar, such as increased thirst, increased need to urinate and increased hunger, although these are common later on in pregnancy anyway.Low blood sugar symptoms, on the other hand, include sweating, shaking, headaches, seizures, dizziness, confusion, blurred vision and personality change, as well as blurred vision, nausea and vomiting.

Usually, all women are screened for gestational diabetes between 24 and 28 weeks’ gestation, using a glucose tolerance test. This testing should be done during the first trimester and then again during the second and third trimesters for women having greater risk factors, even if the first test is negative.
