Pregnancy and diabetes: Why lifestyle counts
Pregnancy and diabetes: Why lifestyle counts
Pregnancy and diabetes — What you need to know to deliver a healthy baby.
When you have diabetes — either type 1 or type 2 — pregnancy presents unique challenges. Naturally, you're concerned about the effect diabetes might have on your health and your baby's health. There's much you can do to promote a healthy pregnancy, however. Here's what you need to know about pregnancy and diabetes — and delivering a healthy baby.
Pregnancy and diabetes: Your health care team
Your diabetes health care team likely includes an endocrinologist or other diabetes specialist, a diabetes educator and a registered dietitian. As your pregnancy progresses, your health care team can help you manage your blood sugar level and adjust your diabetes treatment plan as needed.
During pregnancy, you might need to consult other specialists, including:
- An obstetrician. Choose an obstetrician who handles high-risk pregnancies and has cared for other pregnant women with diabetes. Your obstetrician will carefully monitor your health and your baby's health throughout the pregnancy.
- An eye specialist. An eye specialist can monitor diabetes-related damage to the small blood vessels in your eyes, which can progress during pregnancy.
- A pediatrician. You might also want to establish a relationship with the doctor who will care for your baby after he or she is born.
The goal: Tight blood sugar control
Controlling your blood sugar level before and during pregnancy is the best way to prevent diabetes complications. Good blood sugar control during pregnancy can:
- Reduce the risk of miscarriage and stillbirth. Good blood sugar control reduces the risk of miscarriage and stillbirth — primary concerns for pregnancy and diabetes.
- Reduce the risk of premature birth. The better your blood sugar control, the less likely you are to go into preterm labor.
- Reduce the risk of birth defects. Good blood sugar control during early pregnancy greatly reduces your baby's risk of birth defects, particularly those affecting the brain, spine and heart.
- Reduce the risk of excess fetal growth. If you have poor blood sugar control, extra glucose can cross the placenta. This triggers your baby's pancreas to make extra insulin, which can cause your baby to grow too large (macrosomia). A large baby makes vaginal delivery difficult and puts the baby at risk of injury during birth.
- Prevent complications for mom. Good blood sugar control reduces the risk of high blood pressure, preeclampsia — which is high blood pressure that begins after 20 weeks of pregnancy — and other potentially serious pregnancy complications.
- Prevent complications for baby. Sometimes babies of mothers who have diabetes develop low blood sugar (hypoglycemia) shortly after birth because their own insulin production is too high. Good blood sugar control can help promote a healthy blood sugar level for your baby, as well as healthy levels of calcium and magnesium in the blood. Good blood sugar control also helps prevent a yellowish discoloration of the skin and eyes (jaundice) after birth.
The action plan
Your diabetes health care team will help you establish your target blood sugar range. Then it's up to you to make healthy lifestyle choices and follow your diabetes treatment plan.
Remember the basics:
- Check your blood sugar level often. Frequent blood sugar monitoring — at least three times a day — can help you prevent low blood sugar and high blood sugar (hyperglycemia). Remember, controlling your blood sugar level is the best way to promote a healthy pregnancy and prevent diabetes complications.
- Take insulin or other medications as directed. Although oral diabetes medications are sometimes used during pregnancy, your health care provider might recommend switching to insulin instead. Some medications — including certain drugs to treat high blood pressure, such as ACE inhibitors — should not be taken during pregnancy.
- Be flexible. You'll need to adjust your insulin dosage depending on your blood sugar level, what you eat, whether you're vomiting and various other factors. Your stage of pregnancy matters, too. During the last three months of pregnancy, for example, hormones made by the placenta to help the baby grow can block the effect of insulin in your body. As a result, you might need more insulin than usual to counteract that resistance.
- Eat healthy. Your diabetes diet probably includes plenty of fruits, vegetables and whole grains. Although you can eat the same foods during pregnancy, your health care provider or registered dietitian might suggest changes to your meal plan to help you avoid problems with low blood sugar or high blood sugar. It's also important to take prenatal vitamins containing folic acid.
- Include physical activity in your daily routine. Get your health care provider's OK to exercise, then choose activities you enjoy. Aim for at least 150 minutes a week of moderate aerobic activity. If you haven't been active for a while, start slowly. Check your blood sugar level before and after any activity, especially if you take insulin. You might need to eat a snack or adjust your insulin pump's basal rate before exercising to help prevent low blood sugar.
- Schedule regular prenatal checkups. Your health care provider might recommend regular ultrasounds or other prenatal screening tests to monitor your baby's growth and development.
Remember, your health care team is there to help you manage your blood sugar level and prevent complications. If you have questions or concerns, don't hesitate to ask for help.
Labor and delivery: What to expect
Your health care team will help you determine the best time and safest way to deliver your baby. Sometimes labor is allowed to begin naturally. In other cases, labor may need to be induced early to reduce the risk of complications.
During labor, your health care team will closely monitor your blood sugar level and adjust your insulin dosage accordingly. If your baby is too large, an induction isn't successful or you develop complications, you might need a C-section.
After delivery, your attention will turn to your baby — but it's still important to take care of yourself. Continue to check your blood sugar level often, especially if you're breast-feeding. Keeping yourself healthy is the best thing you can do for your baby.
