Gestational Diabetes Mellitus (GDM): Symptoms, Causes, Diagnosis, Treatment, and Prevention

What is Gestational Diabetes Mellitus (GDM)?

Gestational Diabetes Mellitus (GDM) is a type of diabetes that develops during pregnancy. It usually appears in the second or third trimester. GDM happens when your body cannot make enough insulin to control blood sugar levels. As a result, blood sugar rises and can affect both mother and baby. According to the CDC, about 2% to 10% of pregnancies in the United States are affected by gestational diabetes in pregnancy. Early detection and management are important for a healthy pregnancy.

Symptoms of GDM

Often, GDM does not cause clear symptoms. However, some women may notice signs. For example, you might experience:

Increased thirst

Frequent urination

Feeling more tired than usual

Blurry vision

More infections, such as bladder or skin infections

Still, many women have no symptoms at all. Therefore, regular screening during pregnancy is important.

Causes and Risk Factors

Gestational Diabetes Mellitus (GDM) develops when pregnancy hormones make it harder for your body to use insulin. This leads to higher blood sugar. Several risk factors can increase your chances of getting GDM. For instance, you may be at higher risk if you:

Are overweight or obese before pregnancy

Have a family history of diabetes

Are over 25 years old

Had GDM in a previous pregnancy

Have given birth to a baby weighing more than 9 pounds

Belong to certain ethnic groups, such as African American, Hispanic, Native American, or Asian

Even if you have no risk factors, GDM can still develop. So, routine testing is important for all pregnant women.

Diagnosis of GDM

Doctors use a blood test called the glucose challenge test to check for GDM. Usually, this test is done between 24 and 28 weeks of pregnancy. First, you drink a sweet liquid. Then, your blood is tested to see how your body handles sugar. If your blood sugar is high, your doctor may order a second test called the oral glucose tolerance test. This test gives a clearer picture of how your body processes sugar. Early diagnosis helps prevent problems for both mother and baby.

Treatment Options

If you are diagnosed with Gestational Diabetes Mellitus (GDM), treatment focuses on keeping blood sugar levels in a healthy range. Most women can manage GDM with lifestyle changes. However, some may need medicine. Treatment options include:

Eating a balanced diet with healthy foods

Getting regular physical activity, like walking

Checking blood sugar levels as advised by your doctor

Taking insulin or other medicines if needed

Your healthcare team will guide you on the best GDM treatment options for your situation.

Lifestyle Tips and Management

Managing gestational diabetes in pregnancy is important for your health and your baby’s health. Here are some helpful tips:

Eat small, regular meals to keep blood sugar steady

Choose whole grains, lean proteins, and plenty of vegetables

Limit sugary foods and drinks

Stay active with safe exercises, such as walking or swimming

Monitor your blood sugar as recommended

Keep all prenatal appointments

With these steps, you can help control your blood sugar and reduce risks.

Prevention Strategies

While not all cases of GDM can be prevented, some steps may lower your risk. For example, you can:

Maintain a healthy weight before pregnancy

Eat a balanced diet rich in fiber and low in added sugars

Exercise regularly before and during pregnancy

See your doctor for early prenatal care

By following these prevention tips, you may reduce your chances of developing gestational diabetes. Learning how to prevent gestational diabetes can benefit you and your baby.

When to See a Doctor

If you are pregnant and have risk factors for GDM, talk to your doctor early. Also, if you notice symptoms like extreme thirst or frequent urination, let your healthcare provider know. Regular prenatal visits are key. Early testing and treatment can help prevent problems. Remember, your doctor is your best resource for questions about gestational diabetes in pregnancy.
