Pregnancy glossary G - Gestation period to Glucose screening test

Gestation period

The period of development of the embryo/fetus from the time of conception until birth.

Gestational age

The age of the embryo/fetus since time of conception. If referring to gestational age versus menstrual age, a full-term pregnancy lasts 266 days, or 38 weeks.

Gestational diabetes

Diabetes is a chronic health condition where the body is unable to produce insulin and properly break down sugar (glucose) in the blood. Symptoms include hunger, thirst, excessive urination, dehydration and weight loss. The treatment of diabetes may require daily insulin injections, proper nutrition and regular exercise. Some women experience the onset of gestational diabetes during pregnancy but with careful management, this usually goes away after delivery.

Glucose screening test

This is a screening test for gestational diabetes and is performed by giving a glucose drink and then measuring the blood sugar level one hour later. If the blood sugar level is found to be greater than 140 milligrams per deciliter, the test is considered abnormal or 'positive'.
