Gestational Diabetes: What to Expect & How to Manage It

by Ella

Gestational diabetes is a type of diabetes that occurs during pregnancy. It affects approximately 7% of pregnancies, making it a common condition that requires careful management. While it can be worrisome for expectant mothers, understanding what to expect and how to effectively manage gestational diabetes can help ensure a healthy pregnancy and delivery. In this article, we will explore the causes, symptoms, diagnosis, potential risks, and strategies for managing gestational diabetes.


1. What is Gestational Diabetes?

Gestational diabetes is a form of diabetes that develops during pregnancy. It occurs when the body becomes less efficient at using insulin, resulting in high blood sugar levels. This condition typically develops around the 24th to 28th week of pregnancy and, in most cases, resolves after childbirth. However, women diagnosed with gestational diabetes are at a higher risk of developing type 2 diabetes later in life.


2. Causes and Risk Factors

The exact cause of gestational diabetes remains unclear, but hormonal changes during pregnancy play a significant role. As the placenta grows, it produces hormones that can impair the action of insulin, leading to insulin resistance. Certain risk factors increase the likelihood of developing gestational diabetes, including obesity, a family history of diabetes, polycystic ovary syndrome (PCOS), and previous gestational diabetes.


3. Symptoms and Diagnosis

Gestational diabetes often does not present noticeable symptoms. However, some women may experience increased thirst, frequent urination, fatigue, and blurred vision. Routine screening for gestational diabetes is typically conducted between the 24th and 28th weeks of pregnancy. The oral glucose tolerance test (OGTT) is commonly used to diagnose the condition.


4. Potential Risks and Complications

Gestational diabetes, if left unmanaged, can lead to various complications for both the mother and the baby. It increases the risk of pre-eclampsia, high blood pressure, and future type 2 diabetes for the mother. For the baby, it raises the chances of macrosomia (large birth weight), low blood sugar after birth, respiratory distress syndrome, and an increased risk of developing obesity and type 2 diabetes later in life.

5. Managing Gestational Diabetes

The good news is that gestational diabetes can be managed effectively through lifestyle modifications and, in some cases, medication. A well-balanced diet, regular physical activity, monitoring blood sugar levels, and maintaining a healthy weight are fundamental components of managing gestational diabetes. Medical professionals may also prescribe insulin injections or oral medications to help control blood sugar levels.

6. Diet and Nutrition

A registered dietitian can work with pregnant women diagnosed with gestational diabetes to create personalized meal plans that promote stable blood sugar levels. The emphasis is on consuming a balanced diet consisting of whole grains, lean proteins, healthy fats, and a variety of fruits and vegetables. Portion control and careful carbohydrate management are key aspects of managing gestational diabetes through diet.

7. Physical Activity and Exercise

Regular physical activity can aid in managing blood sugar levels and promoting overall health during pregnancy. Engaging in low-impact exercises such as walking, swimming, and prenatal yoga can provide numerous benefits. However, it is essential to consult with a healthcare provider before starting an exercise regimen to ensure safety and suitability for individual circumstances.

8. Blood Sugar Monitoring

Frequent blood sugar monitoring is crucial in managing gestational diabetes. This involves regularly checking blood sugar levels at home using a glucometer. Keeping a record of blood sugar readings helps identify patterns and determine the effectiveness of dietary changes, exercise, and any prescribed medications.

9. Regular Prenatal Care

Regular prenatal care is essential for monitoring the progress of both mother and baby throughout pregnancy. Healthcare providers will closely monitor blood sugar levels, conduct necessary tests, and provide guidance on managing gestational diabetes. Open communication with healthcare professionals ensures timely adjustments to treatment plans, if required.


Gestational diabetes, though challenging, can be effectively managed with proper care, lifestyle modifications, and medical support. By understanding the causes, symptoms, potential risks, and strategies for managing gestational diabetes, expectant mothers can take proactive steps to ensure a healthy pregnancy and pave the way for a smooth delivery. Seeking support from healthcare professionals, following a well-balanced diet, engaging in regular physical activity, and diligently monitoring blood sugar levels are key components of successful management. With appropriate measures in place, women diagnosed with gestational diabetes can experience positive outcomes.
