Gestational diabetes is a form of diabetes that may arise during pregnancy in women who do not already have diabetes. It affects 2% to 10% of pregnancies annually in the United States. Effectively managing gestational diabetes is crucial to ensure a healthy pregnancy and the well-being of both the mother and the baby.
What causes Gestational diabetes
Gestational diabetes occurs when the body doesn't produce enough insulin during pregnancy. Insulin, a hormone produced by the pancreas, facilitates the entry of blood sugar into cells for energy utilization.
Throughout pregnancy, hormonal changes and weight gain lead to decreased insulin effectiveness, known as insulin resistance. This resistance elevates the body's demand for insulin. While insulin resistance is typical in late pregnancy for all women, some may experience it even before conception, resulting in an increased predisposition to gestational diabetes.
Symptoms
Gestational diabetes often does not present noticeable signs or symptoms. However, increased thirst and more frequent urination may occur in some cases.
Complications
When gestational diabetes isn't carefully managed, it can lead to elevated blood sugar levels, posing risks for both you and your baby. These complications include an increased likelihood of requiring a cesarean section (C-section) for delivery.
Complications affecting your baby
If you have gestational diabetes, your baby may be at a higher risk of experiencing:
Excessive birth weight: Elevated blood sugar levels can lead to the growth of a larger-than-average baby, increasing the likelihood of difficulties during delivery, such as getting stuck in the birth canal or requiring a C-section birth.
Early (preterm) birth: High blood sugar levels may elevate the risk of premature labor and delivery or prompt early delivery due to the baby's large size.
Serious breathing difficulties: Babies born prematurely may face respiratory distress syndrome, which can make breathing challenging.
Low blood sugar (hypoglycemia): Some babies may experience low blood sugar shortly after birth, with severe cases potentially leading to seizures. Prompt feeding or intravenous glucose solutions can help normalize the baby's blood sugar levels.
Increased risk of obesity and type 2 diabetes later in life: Babies born to mothers with gestational diabetes are more likely to develop obesity and type 2 diabetes in adulthood.
Stillbirth: Untreated gestational diabetes can increase the risk of fetal death either before or shortly after birth.
Complications affecting you
Gestational diabetes may also increase your risk of experiencing:
High blood pressure and preeclampsia: Gestational diabetes raises the chances of developing high blood pressure and preeclampsia, a serious pregnancy complication that endangers both your and your baby's health.
C-section delivery: Women with gestational diabetes are more likely to undergo a C-section for delivery.
Future diabetes: Having gestational diabetes increases the likelihood of experiencing it again in future pregnancies. Additionally, there's a higher risk of developing type 2 diabetes as you age.
Prevention:
While there's no foolproof way to prevent gestational diabetes, adopting healthy habits before pregnancy can significantly reduce your risk. If you've previously had gestational diabetes, these healthy choices can also lower your chances of recurrence in future pregnancies or developing type 2 diabetes later on.
Eat a balanced diet: Prioritize foods rich in fiber, while keeping fat and calorie intake low. Emphasize fruits, vegetables, and whole grains in your meals for both taste and nutrition. Be mindful of portion sizes to maintain control over your food intake.
Stay physically active: Engaging in regular exercise before and during pregnancy can lower the risk of gestational diabetes. Aim for at least 30 minutes of moderate activity most days of the week. Simple activities like brisk walks, cycling, or swimming can make a significant difference. Incorporate short bursts of activity into your daily routine, such as parking farther away when running errands or taking brief walks.
Begin pregnancy at a healthy weight: If you're planning to conceive, shedding excess weight beforehand can contribute to a healthier pregnancy. Focus on establishing sustainable changes to your eating habits, such as increasing your intake of vegetables and fruits.
Manage weight gain appropriately: While gaining some weight during pregnancy is natural and healthy, rapid weight gain can elevate the risk of gestational diabetes. Consult your healthcare provider to determine a suitable weight gain range for you, and aim to stay within those guidelines throughout your pregnancy.
