Diabetes in Pregnancy
Gestational diabetes refers to diabetes that is diagnosed during pregnancy. Gestational diabetes occurs in about 15 percent of all pregnancies in India usually in the second half of the pregnancy. It almost always goes away as soon as your baby is born. However, if gestational diabetes is not treated during your pregnancy, you may experience some complications.
Causes
Pregnancy hormones cause the body to be resistant to the action of insulin, a hormone made by your pancreas that helps your body use the fuels supplied by food.
The carbohydrates you eat provide your body with a fuel called glucose, the sugar in the blood that nourishes your brain, heart, tissues and muscles. Glucose also is an important fuel for your developing baby. When gestational diabetes occurs, insulin fails to effectively move glucose into the cells that need it. As a result, glucose accumulates in the blood, causing blood sugar levels rise.
Diagnosis
Gestational diabetes is diagnosed with a blood test. Your blood glucose level is measured after you drink a 25….. If your blood sugar is too high, you have gestational diabetes. Sometimes one test is all that is needed to make a definitive diagnosis. More often, an initial screening test is given and, if needed, a longer evaluation is performed.
Gestational diabetes usually does not occur until later in pregnancy, when the placenta is producing more of the hormones that interfere with the mother's insulin. Screening for gestational diabetes usually takes place between weeks 24 to 28. However, women at high risk are usually screened during the first trimester.
Risk Factors
There are a number of risk factors associated with gestational diabetes, including:
Gestational Diabetes and Your Baby
Gestational diabetes can impact your developing baby in a couple of ways:
Avoiding Complications
Remember that the complications of gestational diabetes can be prevented by keeping your blood sugar under control during your pregnancy. The goal of treatment is to keep your blood sugar in the normal range. Most women with well-controlled blood sugar deliver healthy babies without any complications.
Treatment
Diet
The first step in treating gestational diabetes is to modify your diet to help keep your blood sugar level in the normal range. You should meet with a registered dietitian to develop a customized eating plan to help you manage your blood sugar. You may also wish to read Dietary Recommendations for Gestational Diabetes.
The main principles for diet include:
Blood Sugar Monitoring
The only way to know that your gestational diabetes is being properly controlled is to check your blood sugar frequently. You will be instructed on the use of a home blood sugar monitor. Check your fasting blood sugar first thing in the morning, before you have had anything to eat or drink. Also check your blood sugar 2 hour after starting to eat your three main meals: breakfast, lunch and dinner. Check with your doctor for target blood sugar levels.
Other Treatments
The majority of women with gestational diabetes will be able to control their blood sugar simply by modifying their diet. You will need to follow the diet guidelines until your baby is born. After delivery, most women are able to resume their normal eating habits. Gestational diabetes does not interfere with your ability to breastfeed your baby.
For about 30 percent of the women who develop gestational diabetes, following a diet is not enough to control their blood sugar. For these women, insulin therapy is usually initiated. Using insulin is safe during pregnancy. Women who take insulin still need to continue with the prescribed diet and monitor their blood sugar levels.
After Delivery
After your baby is born, your blood sugar will be checked to make sure it is normal. Fortunately, gestational diabetes almost always goes away after your baby is born. If your blood sugar does not return to normal, it may mean that you had diabetes before you became pregnant.
The most important thing to remember is to check your blood sugar before you become pregnant again. Women who had gestational diabetes have an increased risk of developing type 2 diabetes. Women who had diabetes before they become pregnant have an increased risk of pregnancy complications. Elevated maternal blood sugar during the first 12 weeks of pregnancy, when the major organ systems are developing, increases risks to the fetus. Women with diabetes can help improve their chances of having a healthy baby by normalizing their blood sugar before becoming pregnant.
