Gestational diabetes is one of the most common complications of pregnancy. It usually develops during the second half of pregnancy when hormones interfere with the body`s ability to produce insulin. Unlike other forms of diabetes, gestational diabetes usually goes away when the baby is born. However, women who experience gestational diabetes are at an increased risk of developing diabetes in the future.

Most women with gestational diabetes can control their blood sugar levels with diet, although 10% to 15% require insulin injections.

Diet

A pregnant woman with diabetes should follow a special diet designed for her. For women with pre-existing diabetes, dietary modifications will also be required as pregnancy progresses.

How many calories a pregnant woman with diabetes should eat, and the proportion of foods from the various food groups will depend on many factors including height, weight, stage of pregnancy, and the baby`s growth rate. Our doctors and nurses will work to help you plan your diet.

Exercise

Exercise can help control diabetes by prompting the body to use insulin more efficiently. However, you should always consult with our doctors and nurses about starting or continuing your exercise program.

Insulin

Many women with pre-existing diabetes require insulin injections to keep their blood sugar levels under control. Insulin requirements change during pregnancy, generally increasing after 20 to 24 weeks and stabilizing by about 36 weeks.

Most pregnant women with gestational diabetes do not require insulin. However, if blood sugar levels do not stabilize after 2 weeks on a special diet, one or more insulin injections may be needed daily for the remainder of the pregnancy.

Monitoring Blood Glucose and Urine at Home

To measure how effectively your diet, exercise, and insulin (if you require it) are controlling your blood glucose, you will need to monitor your blood glucose levels several times each day. You may also be asked to perform a urine test to measure the levels of ketones in your urine. Moderate to large amounts of ketones in the urine can be a sign of complications that must be promptly treated.
