Gestational Diabetes Diagnosis

Gestational Diabetes Diagnosis

Gestational diabetes is a form of diabetes that develops during pregnancy. It usually appears between 24 and 28 weeks of gestation and typically resolves after delivery. Early diagnosis is important to protect both mother and baby and to reduce the risk of complications.

Recognising the Risk Factors

Not all women with gestational diabetes show noticeable symptoms. Key risk factors include being overweight, having a family history of diabetes, previous gestational diabetes, having previously given birth to a large baby, and belonging to higher-risk ethnic groups such as South Asian, African Caribbean, or Middle Eastern. Awareness of these factors helps identify women who should be tested early.

Medical Testing

The primary test for gestational diabetes is the Oral Glucose Tolerance Test (OGTT). This is usually performed between 24 and 28 weeks of pregnancy. The test involves fasting overnight, having a blood test, drinking a glucose solution, and then taking further blood tests over the following two hours to measure how the body processes sugar.

Importance of Early Diagnosis

Early detection allows healthcare professionals to provide guidance on diet, exercise, and monitoring, helping to maintain healthy blood sugar levels. Proper management reduces the risk of complications for both mother and baby, including high birth weight, premature delivery, and preeclampsia.

Follow-Up and Ongoing Care

Women diagnosed with gestational diabetes are often monitored closely throughout the remainder of their pregnancy. After delivery, blood glucose levels are rechecked to ensure the condition has resolved. Women who have had gestational diabetes are at higher risk of developing type 2 diabetes later in life, so ongoing lifestyle management and periodic screening are recommended.
