Gestational DiabetesWhat is gestational diabetes?Gestational diabetes is a type of diabetes that happens during pregnancy. Unlike type 1 diabetes, gestational diabetes is not caused by having too little insulin. Instead a hormone made by your placenta keeps your body from using the insulin as it should. This is called insulin resistance. Blood sugar (glucose) then builds up in your blood instead of being absorbed by the cells in your body. The symptoms of gestational diabetes often go away after delivery. But sometimes they don't. Or you may have a greater risk of developing type 2 diabetes later. What causes gestational diabetes?Healthcare providers don't know what causes gestational diabetes. But they do know what happens. The placenta gives your growing baby nutrients and water. The placenta also makes several hormones to keep the pregnancy healthy. These hormones include:
These hormones can affect how your body uses insulin (contra-insulin effect). This often begins about 20 to 24 weeks into your pregnancy and could lead to gestational diabetes. During pregnancy, more fat is stored in your body, you take in more calories, and you may get less exercise. All of these things can make your blood sugar (glucose) levels higher than normal and possibly lead to gestational diabetes. As the placenta grows, it makes more of the hormones. The risk for insulin resistance becomes greater. Normally your pancreas is able to make more insulin to overcome insulin resistance. But if it can't make enough to overcome the effects of the placenta’s hormones, you can develop gestational diabetes. Who is at risk for gestational diabetes?Any woman can develop gestational diabetes during pregnancy. But you may be more likely to get it if you:
What are the symptoms of gestational diabetes?Gestational diabetes doesn't cause any symptoms. That’s why it’s important to get tested for it if you are at high risk. If your blood sugar levels are very high, you may have these symptoms:
How is gestational diabetes diagnosed?You should be tested for gestational diabetes in your 24th to 28th week of pregnancy. The American Diabetes Association also advises that you be tested for type 2 diabetes if you have risk factors for this condition. This testing should be done at your first prenatal visit. Screening is done by these tests:
If you are diagnosed with gestational diabetes, you should get tested for diabetes 4 to 12 weeks after your baby is born. You should also get this screening at least every 3 years for the rest of your life. What is the treatment for gestational diabetes?You and your healthcare provider will figure out the best treatment for you based on:
Treatment for gestational diabetes focuses on keeping your blood sugar levels in the normal range. Treatment may include:
What are possible complications of gestational diabetes?Gestational diabetes usually doesn't cause birth defects. But it can affect your baby in other ways if your blood sugar levels are not under control. Below are the 2 major health problems that can develop. MacrosomiaMacrosomia means a baby who is much larger than normal. This happens if the mother’s blood has too much blood sugar in it. The fetus’ pancreas senses this high level of blood sugar and makes more insulin. The fetus then changes the extra blood sugar into fat. This extra fat means a larger baby. A larger than normal baby can be difficult to deliver. The baby may have trauma or nerve damage, or need to be delivered by cesarean section. HypoglycemiaHypoglycemia is low blood sugar. This can happen to the baby just after he or she is born if the mother’s blood sugar levels are too high. The high levels in the mother cause the fetus to make more insulin. Once the baby is born, he or she no longer has the high blood sugar levels from the mother. This causes the baby’s blood sugar levels to fall very low. Your blood sugar levels will be watched very closely during labor. Your healthcare provider may give you insulin to keep your blood sugar in a normal range. This will prevent your baby's blood sugar from dropping greatly after delivery. Babies born to mothers with gestational diabetes may also have low levels of calcium or magnesium in their blood. These complications can be prevented. The key to prevention is careful control of your blood sugar levels just as soon as the diagnosis of diabetes is made. Key points about gestational diabetes
Next stepsTips to help you get the most from a visit to your healthcare provider:
Does gestational diabetes during pregnancy affect baby?If untreated, gestational diabetes can cause problems for your baby, such as premature birth and stillbirth. Gestational diabetes usually goes away after the baby's born; but if you have it, you're more likely to develop diabetes later in life.
Is gestational diabetes considered high risk pregnancy?Women who develop diabetes during pregnancy, known as gestational diabetes mellitus (GDM), may need high-risk pregnancy care due to complications that can arise during pregnancy and childbirth. Women with GDM have an increased risk of preeclampsia, a condition that leads to pregnancy-induced high blood pressure.
Can you carry a baby full term with gestational diabetes?You should be able to. Having gestational diabetes (GD) doesn't necessarily mean that you can't have your baby vaginally. You've got a better chance of having a birth without any interventions, such as induction or caesarean section, if you can keep your blood sugar levels stable during pregnancy.
