Understanding Gestational Diabetes Mellitus

Recent research conducted across seven antenatal clinics involving over 3,000 women reveals that early Gestational Diabetes Mellitus (GDM) affects approximately one in five pregnant women. This condition is crucial for expectant mothers to understand.

What is Gestational Diabetes Mellitus?

Gestational Diabetes Mellitus (GDM) is defined as glucose intolerance that is first identified during pregnancy, generally diagnosed between 24 and 28 weeks of gestation. It occurs when hormonal changes from the placenta hinder the body's ability to utilize or produce insulin effectively.

Causes of GDM

The underlying cause of GDM is the hormones produced by the placenta, which can interfere with insulin action. This phenomenon is known as the contra-insulin effect, typically starting around the 20th to 24th week of pregnancy. The placenta plays a vital role in nourishing the developing fetus by supplying essential nutrients and water.

Symptoms of Gestational Diabetes

Often, GDM does not present noticeable symptoms. However, some women may experience:

  • Excessive thirst
  • Frequent urination
  • Fatigue
  • Nausea

Risk Factors for Developing GDM

Several risk factors can increase the likelihood of developing GDM, including:

  • Being overweight or obese
  • Age over 45
  • Family history of diabetes or GDM in previous pregnancies
  • Having polycystic ovary syndrome (PCOS)

Treatment and Management of GDM

Managing gestational diabetes often involves a combination of lifestyle modifications and medication. A balanced diet, regular physical activity, and monitoring blood glucose levels are key components in controlling GDM effectively.
