Type 1 and Type 2 Diabetes During Pregnancy

Consult with the maternal-fetal medicine team.

If you have Type 1 or Type 2 diabetes before becoming pregnant (pregestational diabetes), your pregnancy may require additional monitoring and specialized care.

Diabetes mellitus, which includes Type 1 diabetes, Type 2 diabetes and gestational diabetes, can increase the risk of certain complications, but having diabetes does not mean you cannot have a healthy pregnancy and baby. Careful blood sugar management, planning before pregnancy and appropriate prenatal care can help reduce risks.

The Wendy Novak Diabetes Institute Perinatal Program, in collaboration with Norton Children’s Maternal-Fetal Medicine, provides specialized care for people with diabetes before, during and after pregnancy. Your care team can work with your regular OB/GYN and diabetes care providers to develop a plan for managing your health and monitoring your baby throughout pregnancy.

Pregestational diabetes was present before pregnancy or was diagnosed before you became pregnant.

It includes:

  • Type 1 diabetes
  • Type 2 diabetes
  • Other forms of diabetes that were present before pregnancy

Gestational diabetes develops during pregnancy in someone who did not have diabetes before conceiving.

If you have Type 1 or Type 2 diabetes and are considering pregnancy, planning your care before conception is an important part of reducing pregnancy risks.

Diabetes can make a pregnancy more complex because changes in blood glucose can affect both your health and your baby’s development.

Factors that include how well your glucose levels are controlled, how long you have had diabetes and whether you have other health conditions or diabetes-related complications determine your individual risk.

Having diabetes does not mean that pregnancy complications are inevitable.

Norton Children’s Maternal-Fetal Medicine specialists have experience, expertise and training to care for pregnancies affected by Type 1 or Type 2 diabetes.

Good blood glucose management and regular prenatal care can help reduce risks.

Potential Health Concerns for Mom

Pregestational diabetes can increase the risk of:

  • High blood pressure during pregnancy
  • Preeclampsia
  • Cesarean delivery
  • Low blood glucose, particularly when diabetes treatment is intensified during pregnancy
  • Worsening of certain diabetes-related complications

Your healthcare team will monitor your blood pressure, blood glucose and overall health throughout pregnancy.

Potential Health Concerns for Baby

Pregestational diabetes also can increase the risk of complications affecting your baby, including:

  • Certain birth defects
  • Excessive fetal growth
  • Restricted fetal growth
  • Miscarriage
  • Stillbirth
  • Preterm birth
  • Birth injuries associated with excessive fetal growth

The level of risk varies from person to person. Blood glucose control before and during pregnancy is an important part of reducing the risk of complications.

Yes. People with Type 1 or Type 2 diabetes routinely have healthy pregnancies and healthy babies.

Planning ahead gives you and your care team an opportunity to address factors that can affect pregnancy before conception. This may include reviewing your blood glucose control, medications, nutrition and any diabetes-related health conditions.

Once you are pregnant, your care team can monitor your health and your baby’s growth and development closely.

A Norton Children’s Maternal-Fetal Medicine specialist can work alongside your regular OB/GYN rather than replacing your existing pregnancy care.

If you have diabetes and are considering pregnancy, make an appointment with your healthcare provider before trying to conceive.

Your preconception visit may include:

  • Reviewing blood glucose control. Your provider will review your blood glucose history and may check your A1C level or other measures of diabetes control. The goal is to optimize blood glucose before pregnancy, because a baby’s organs begin developing very early in pregnancy.
  • Reviewing medications. You may need to change some medications you are taking before conception. Do not stop taking a diabetes medication on your own. Talk with your diabetes care team about which medications are appropriate before and during pregnancy.
  • Reviewing nutrition and physical activity. Your care team can help you establish an eating and activity plan that supports your health and pregnancy goals.
  • Taking prenatal vitamins and folic acid. Ask your provider which prenatal vitamin and amount of folic acid are appropriate for you. Pregnancy planning should include a discussion of prenatal vitamins and folic acid.
  • Checking for diabetes-related health conditions. Diabetes can affect organs such as the eyes and kidneys. Your care team may recommend checking for diabetes-related complications before pregnancy or early in pregnancy.
  • Developing a glucose-monitoring plan. Your blood sugar level needs may change during pregnancy. Establishing a monitoring plan before conception can help you understand how your treatment may need to change as pregnancy progresses.

Managing diabetes during pregnancy is a team effort. Your care plan may include:

  • Regular monitoring of blood glucose levels
  • Continuous glucose monitoring when appropriate
  • Nutrition counseling
  • Physical activity appropriate for your pregnancy
  • Insulin or other medication as recommended
  • Diabetes education
  • More frequent prenatal monitoring

Blood glucose goals during pregnancy can differ from the goals you had before pregnancy. Your healthcare team will establish individualized targets and explain how often to check your blood glucose.

Do not change or stop diabetes medications without talking with your healthcare team.

Pregnancy can change your insulin needs throughout the first, second and third trimesters. Your treatment plan may need to be adjusted.

Your pregnancy care team may recommend additional monitoring based on your type of diabetes, blood glucose control, overall health and other risk factors.

Monitoring may include:

  • Additional prenatal visits
  • Ultrasound examinations to monitor fetal growth
  • Additional fetal testing later in pregnancy
  • Monitoring for high blood pressure and preeclampsia
  • Fetal echocardiography in certain pregnancies

A fetal echocardiogram is a detailed ultrasound examination of the baby’s heart. Your provider will determine whether you need one based on your individual risk factors.

Your diabetes care does not stop when labor begins.

Your healthcare team may monitor your blood glucose during labor and delivery and adjust medication as needed. Your individual plan will depend on your type of diabetes, treatment and pregnancy.

After delivery, insulin and other medication needs can change quickly. Your diabetes care team will tell you how to adjust your treatment and continue monitoring your blood glucose.

Your newborn may need additional monitoring of blood glucose after birth, particularly if you had diabetes during pregnancy.

Breastfeeding is encouraged for many people with diabetes and can offer health benefits for both parent and baby. Talk with your care team about breastfeeding, nutrition and any medication considerations.

Frequently Asked Questions About Diabetes and Pregnancy Risk

Diabetes can make pregnancy more complex and may require additional monitoring. Your individual level of risk depends on factors such as your type of diabetes, blood glucose control, diabetes-related health conditions and other pregnancy factors.

Yes. Many people with Type 1 or Type 2 diabetes have healthy pregnancies and babies. Planning before pregnancy, managing blood glucose and receiving appropriate prenatal care can help reduce risks.
