Glucose intolerance during pregnancy
Usually there are no symptoms, or the symptoms are mild and not life threatening to the pregnant woman. Often, the blood sugar (glucose) level returns to normal after delivery.
Symptoms may include:
Gestational diabetes usually starts halfway through the pregnancy. All pregnant women should receive an oral glucose tolerance test between the 24th and 28th week of pregnancy to screen for the condition. Women who have risk factors for gestational diabetes may have this test earlier in the pregnancy.
Once you are diagnosed with gestational diabetes, you can see how well you are doing by testing your glucose level at home. The most common way involves pricking your finger and putting a drop of your blood on a machine that will give you a glucose reading.
