PLAYING: What’s your blood sugar number?

What’s your blood sugar number?

The key question to ask if you’re being tested for, or monitoring, gestational diabetes.

2 mins to read Jan 4, 2022

Diabetes is a condition where the amount of glucose (a type of sugar) in your blood is too high because your body can’t use it properly. If this happens when you’re pregnant (usually during the second or third trimester), it’s called gestational diabetes. Whether you’re thinking about trying for a baby or are already pregnant, there are things you can do to decrease your chances of getting gestational diabetes or to manage it carefully if you do.

Before you get pregnant:

  • stop smoking
  • eat a healthy diet that includes recommended amounts of fibre, fruit, vegetables, whole grains, lean meat, and dairy food
  • maintain a healthy weight
  • lead an active lifestyle.

When you’re pregnant:

  • continue to follow a healthy, active lifestyle and balanced diet, as above
  • In Canada, most women are tested for gestational diabetes between weeks 24 and 28 of pregnancy in a clinic and using an oral glucose tolerance test.

If you find out you do have gestational diabetes, don’t panic! It can be managed with diet, exercise, and—if needed—medication. Your healthcare providers will come up with a plan that’s tailor-made for you. When your blood glucose is under control, the majority of moms and babies continue to be healthy throughout pregnancy.
