Gestational diabetes - Symptom

Alternative Names

Glucose intolerance during pregnancy

Symptoms:

Usually there are no symptoms, or the symptoms are mild and not life threatening to the pregnant woman. Often, the blood glucose level returns to normal after delivery.

Symptoms may include:

Blurred vision
Fatigue
Frequent infections, including those of the bladder, vagina, and skin
Increased thirst
Increased urination
Nausea and vomiting
Weight loss in spite of increased appetite

However, high blood sugar levels in the mother can cause problems in the baby. These problems can include:

Birth injury (trauma) because of the baby's large size
Increased chance of diabetes and obesity
Jaundice
Large size at birth
Low blood sugar (hypoglycemia)

Rarely, the unborn baby dies in the womb late in the pregnancy. Mothers with gestational diabetes have an increased risk for high blood pressure during pregnancy and delivery by c-section.

Signs and tests:

Gestational diabetes may not cause symptoms. All pregnant women should receive an oral glucose tolerance test between the 24th and 28th week of pregnancy to screen for the condition.
