Gestational diabetes is a common pregnancy complication that causes high blood sugar. The glucose that is released into your bloodstream after digesting food is normally controlled by insulin. During pregnancy, however, your growing placenta produces high levels of hormones that can impair the function of insulin.
If left untreated, gestational diabetes can be harmful to you and can affect the growth and development of your baby. However, by making appropriate diet and lifestyle changes and, in some cases, taking medication, gestational diabetes can usually be successfully managed.
Risk factors for gestational diabetes include:
Because gestational diabetes often does not cause any symptoms, your physician will give you a routine gestational diabetes test sometime between your 24th and 28th week of pregnancy. This screening can take place at your obstetrician’s office or at any UPMC laboratory.
You will be asked to drink a very sweet glucose beverage. An hour later, your blood will be drawn and tested to determine your blood sugar level. If your blood sugar is higher than it should be, your physician will order a follow-up test.
The follow-up screening requires that you fast overnight. In the morning, your blood will be drawn to establish your fasting blood sugar level. You will be asked to drink an even sweeter glucose beverage. Your blood will be tested every hour for three hours. If two of the three tests show a high blood sugar level, you will be diagnosed with gestational diabetes.
Most women are able to control their gestational diabetes by following a careful diet, exercising regularly and making other lifestyle changes. You will need to monitor your blood sugar every day and, in some cases, you may need to receive insulin injections.
If you are diagnosed with gestational diabetes, you will also be referred to a UPMC diabetes educator and dietitian, who will help you learn how to manage your condition and have a healthy pregnancy.
Your physician may also conduct regular ultrasounds and non-stress tests to check the health of your baby. Some women with gestational diabetes can have very large babies or babies who are born with a low blood sugar level. Your physician will work with your pediatrician to ensure that your baby receives appropriate screening and care after birth.
In most cases, gestational diabetes goes away after your baby is born. However, you will have an increased risk of developing diabetes later in life. It is very important that you receive follow-up care from your primary care physician within the first year after delivering your baby.
If you’ve been diagnosed with gestational diabetes, one of the easiest ways to manage your condition is to change your diet. A healthy diet and moderate exercise can help ensure that you have a healthy pregnancy.
Your physician may refer you to a UPMC nutritionist to help you learn how to regulate and stabilize your blood sugar.
