Gestational diabetes, a type of diabetes that develops during pregnancy, affects approximately 2%–10% of all pregnancies in the United States. It usually occurs during the second or third trimester and typically resolves after delivery. However, if left untreated, gestational diabetes can increase the risk of complications for both the mother and the baby.
Signs and Symptoms of Gestational Diabetes
-
Excessive thirst: Feeling thirsty more often than usual can be a sign of gestational diabetes. When your blood sugar levels are high, your body tries to flush out the excess sugar by producing more urine, leading to dehydration and increased thirst.
-
Frequent urination: Producing more urine can lead to frequent trips to the bathroom. High blood sugar levels can cause the kidneys to filter more glucose from the blood, resulting in increased urine production.
-
Increased hunger: Feeling hungry all the time can be another symptom of gestational diabetes. When your body is unable to use glucose effectively, it may send signals to the brain that it needs more food.
-
Tiredness and fatigue: Feeling unusually tired or fatigued can be a sign of high blood sugar levels. When your body is working hard to process glucose, it can lead to exhaustion and fatigue.
-
Blurred vision: High blood sugar levels can cause the lenses in your eyes to swell, leading to blurred vision. This symptom usually resolves after blood sugar levels are controlled.
-
Frequent infections: Women with gestational diabetes may be more susceptible to infections, such as yeast infections or urinary tract infections. High blood sugar can weaken the immune system, making it more difficult for the body to fight off infections.
Risk Factors for Gestational Diabetes
Certain factors can increase a woman’s risk of developing gestational diabetes, including:
-
Overweight or obesity: Women who are overweight or obese before pregnancy are more likely to develop gestational diabetes.
-
Family history of diabetes: Having a family history of diabetes, especially type 2 diabetes, increases the risk of developing gestational diabetes.
-
Advanced maternal age: Women over the age of 35 are at an increased risk of developing gestational diabetes.
-
Prior history of gestational diabetes: Women who have had gestational diabetes in previous pregnancies are more likely to develop it again.
Diagnosis and Treatment of Gestational Diabetes
Gestational diabetes is typically diagnosed through a blood test called a glucose tolerance test. This test measures blood sugar levels after consuming a sugary drink. Treatment for gestational diabetes involves managing blood sugar levels through diet, exercise, and, if necessary, medication. A healthy diet for gestational diabetes includes plenty of fruits, vegetables, whole grains, and lean protein. Regular exercise can help improve insulin sensitivity and lower blood sugar levels. In some cases, insulin injections may be necessary to control blood sugar levels.
Complications of Gestational Diabetes
If left untreated, gestational diabetes can increase the risk of complications for both the mother and the baby. For the mother, gestational diabetes can increase the risk of:
-
Preeclampsia: A condition characterized by high blood pressure and protein in the urine.
-
Cesarean delivery: Women with gestational diabetes are more likely to need a cesarean delivery due to the increased risk of fetal macrosomia (large baby).
-
Future type 2 diabetes: Women who have had gestational diabetes are at an increased risk of developing type 2 diabetes later in life.
For the baby, gestational diabetes can increase the risk of:
-
Macrosomia: A condition in which the baby is born with a high birth weight, which can increase the risk of birth injuries and childhood obesity.
-
Low blood sugar (hypoglycemia): Babies born to mothers with gestational diabetes may have low blood sugar levels at birth.
-
Stillbirth: In severe cases, gestational diabetes can increase the risk of stillbirth.
Prevention of Gestational Diabetes
While it is not always possible to prevent gestational diabetes, there are certain lifestyle changes that can help reduce the risk:
-
Maintain a healthy weight: Women who are overweight or obese before pregnancy should aim to lose weight before conceiving.
-
Eat a healthy diet: A healthy diet rich in fruits, vegetables, whole grains, and lean protein can help prevent gestational diabetes.
-
Get regular exercise: Regular exercise can help improve insulin sensitivity and lower blood sugar levels.
-
Manage blood sugar levels: Women with a family history of diabetes or other risk factors for gestational diabetes should monitor their blood sugar levels throughout pregnancy.
Conclusion
Gestational diabetes is a serious condition that can affect both the mother and the baby. However, it can be managed with a healthy lifestyle and, if necessary, medication. By recognizing the signs and symptoms of gestational diabetes and taking steps to manage blood sugar levels, women can help reduce the risks associated with this condition.
