What Can I Eat if I Have Gestational Diabetes? Food List and More

What is gestational diabetes?

food to manage gestational diabetes

Gestational diabetes is diabetes that only occurs in pregnant women. That means you can't get gestational diabetes unless you’re pregnant. You may develop gestational diabetes for the first time during pregnancy or you might have a mild undiagnosed case of diabetes that gets worse when you’re pregnant.

During pregnancy, the way your body uses insulin changes. Insulin is a hormone that breaks the foods you eat down into glucose, or sugar. You then use that glucose for energy.

You’ll naturally become more resistant to insulin when you’re pregnant to help provide your baby with more glucose. In some women, the process goes wrong and your body either stops responding to insulin or doesn't make enough insulin to give you the glucose you need. When that happens, you’ll have too much sugar in your blood. That causes gestational diabetes.

Complications

What are the complications?

Gestational diabetes can be risky to both you and your baby. The extra glucose in your body can make your baby gain weight. A bigger baby puts you at risk for having a more difficult delivery because:

  • the baby's shoulders can get stuck
  • you can bleed more
  • the baby may have a hard time keeping their blood sugar stable and breathing after birth

Gestational diabetes also increases your risk of high blood pressure during pregnancy.

In most cases, gestational diabetes disappears after your baby is born. But if you had diabetes before pregnancy, you will still have it. Having gestational diabetes does put you at an increased risk of developing diabetes later on in life, too. Both you and your baby will be checked for diabetes after birth.
