Understanding Gestational Diabetes Mellitus (GDM)

Gestational Diabetes Mellitus (GDM) is a condition characterized by high blood sugar (glucose) levels that are first diagnosed during pregnancy. It affects how your cells use sugar and can impact both the mother’s health and the baby’s development. Understanding the causes, risks, and management strategies is crucial for a healthy pregnancy outcome.

What Causes Gestational Diabetes?

During pregnancy, the placenta produces hormones that support the baby’s growth. These hormones, such as human placental lactogen (hPL) and others, can also block the action of the mother’s insulin in her body. This is called insulin resistance. As the placenta grows, more of these hormones are produced, and insulin resistance becomes greater. For most women, the pancreas can make enough additional insulin to overcome this resistance, but for some, it cannot, leading to GDM.

Key Risk Factors

Certain factors increase the likelihood of developing GDM. While any pregnant woman can develop it, the risk is higher for those who:

• Are overweight or have obesity (BMI > 30)
• Have a personal history of GDM in a previous pregnancy
• Have a family history of type 2 diabetes
• Are of certain ethnic backgrounds (e.g., African American, Hispanic, Asian American)
• Are older than 25
• Have polycystic ovary syndrome (PCOS)

Symptoms and Screening

GDM often doesn’t have noticeable symptoms, which is why screening is a routine part of prenatal care. If symptoms do occur, they can be mild, such as increased thirst or more frequent urination. Screening is typically performed between 24 and 28 weeks of gestation using a glucose challenge test, followed by an oral glucose tolerance test (OGTT) if the initial screen is positive.

Managing GDM: Diet and Exercise

The primary goal of GDM management is to keep blood sugar levels within a target range. This is often achieved through lifestyle modifications:

1. Dietary Changes: Working with a registered dietitian to create a meal plan that balances carbohydrates, proteins, and fats. The focus is on complex carbohydrates and distributing intake throughout the day to prevent blood sugar spikes.
2. Physical Activity: Engaging in regular, moderate exercise, such as walking or swimming, for at least 30 minutes on most days of the week. Exercise helps the body use insulin more effectively.

Monitoring Blood Sugar Levels

Women with GDM are typically required to monitor their blood glucose levels multiple times a day using a home glucose meter. This usually involves checking fasting levels in the morning and then 1-2 hours after each meal. These readings help the healthcare team determine if the current management plan is effective or if medication, such as insulin, is needed.

Life After Gestational Diabetes

For most women, blood sugar levels return to normal soon after delivery. However, having GDM increases the risk of developing type 2 diabetes later in life. It’s recommended to have a follow-up glucose test 6 to 12 weeks postpartum and then every 1 to 3 years to monitor for diabetes.
