Gestational Diabetes

Gestational diabetes is a type of diabetes that some women get during pregnancy.

You treat it by making certain eating changes, exercising, checking blood sugar levels, and possibly taking diabetes medicine or insulin shots. With treatment, most women who have gestational diabetes will have healthy babies.

Gestational diabetes usually goes away after the baby is born.

  • Symptoms

    What are the symptoms of gestational diabetes?

    Gestational diabetes may not cause symptoms, so you need to be tested for it.

    Sometimes a pregnant woman has been living with another type of diabetes without knowing it. Common symptoms of high blood sugar include:

    • Feeling very thirsty.
    • Urinating more often than usual.
    • Feeling very hungry.
    • Having blurred vision.

    Most pregnant women urinate more often and feel more hungry. So having these symptoms doesn't always mean that a woman has diabetes. But if you have these symptoms at any time during pregnancy, talk with your doctor so that you can be tested for diabetes.

  • Causes

    What causes gestational diabetes?

    Insulin is a hormone made by the pancreas. Insulin helps your body use and store the sugar from the food you eat. This keeps your blood sugar level in a safe range.

    During pregnancy, the placenta makes several other hormones. Some of these hormones make it hard for insulin to do its job. The mother's body needs to make more insulin to control sugar levels. Gestational diabetes develops when her body can't make enough insulin to keep blood sugar levels in a safe range.

  • Prevention

    What can you do to prevent gestational diabetes?

    In some women, gestational diabetes can't be prevented. But you may lower your risk if you stay at a healthy weight and don't gain too much weight during pregnancy. Regular exercise can also help keep your blood sugar level within a target range. This can help prevent gestational diabetes.

  • Treatment

    How is gestational diabetes treated?

    Controlling your blood sugar is the key to preventing problems during pregnancy and birth. You may be able to control your blood sugar with healthy eating and regular moderate exercise. If you keep up with these healthy habits, they can help prevent gestational diabetes in a future pregnancy. They can also help prevent type 2 diabetes later in life.

    You'll need to check your blood sugar at home to see if it's staying in a target range. If it isn't, you may need to take diabetes medicine or give yourself insulin shots.

    It's also important to have regular medical checkups. At each visit, your doctor will do tests to see how you and your baby are doing.
