About 2 to 4 % (and up to 18 % in some populations) of Canadian women will develop diabetes during pregnancy. This is called gestational diabetes. Gestational diabetes is defined as high blood sugar which is first diagnosed during pregnancy.

You have a greater chance of developing gestational diabetes if you:

• Have had diabetes in a previous pregnancy
• Have had a large birth weight baby (over 4.5 kg or 9 lbs)
• Are over 35 years old
• Are overweight or obese
• Are of Aboriginal, Hispanic, South Asian, Asian and African descent
• Have a history of certain health conditions (talk to your health care provider)

Pregnant women are usually tested for gestational diabetes between 24 and 28 weeks gestation. Some of the signs of high blood sugar are feeling thirsty, urinating often, weight loss and feeling tired. Often you will not notice any signs.

High blood sugar can be harmful to you and your baby. If you are diagnosed with diabetes it is important to see a registered dietitian to help you learn how to eat to keep your blood sugar under control. Your health care provider and dietitian can help you to have a healthy pregnancy and give birth to a healthy baby.

Usually your blood sugar will return to normal after you have had the baby. Your health care provider will test your blood sugar to see if it has returned to normal. Women who have had gestational diabetes are more likely to develop type 2 diabetes in the future.

What can you do after pregnancy to stay healthy?

• Breastfeed your baby - it's good for you too
• Stay healthy by eating according to Canada's Food Guide
• Staying active
• Go to your health care provider for regular screening for the development of diabetes
