Overview

  • Develops during pregnancy and usually goes away after birth
  • Caused by hormonal changes affecting insulin function
  • Often has no noticeable symptoms
  • Can be managed with diet, monitoring, and sometimes medication
  • Increases the risk of developing Type 2 Diabetes later in life

What is Gestational Diabetes?

Gestational Diabetes occurs when blood glucose levels become elevated during pregnancy. Hormonal changes can make it harder for the body to use insulin effectively.

This condition is temporary for most people, but it requires careful management to support the health of both parent and baby.

How is it diagnosed?

Gestational Diabetes is usually diagnosed between 24 and 28 weeks of pregnancy.

Risk Factors to Watch For

You may be at higher risk if you:

Are above a healthy weight
Have a family history of diabetes
Have had gestational diabetes in a previous pregnancy
Are over the age of 30
Have previously had a large baby (over 4kg)
Have polycystic ovary syndrome (PCOS)

Signs and Symptoms

In some cases, symptoms may include:

Increased thirst
Frequent urination
Fatigue

Why is Management Important?

Managing gestational diabetes helps reduce risks such as:

  • High birth weight
  • Premature birth
  • Birth complications
  • Low blood glucose in the baby after birth

Good management supports a healthy pregnancy and delivery.

Managing Gestational Diabetes

Management focuses on keeping blood glucose levels within a healthy range.

Key areas include:

  • Healthy eating (guided by a dietitian if needed)
  • Regular physical activity (as advised by your care team)
  • Blood glucose monitoring
  • Medication or insulin (if required)

Your healthcare team will guide you through this process.

After Pregnancy

Gestational diabetes usually resolves after birth, but follow-up care is important.

Important next steps:

  • Blood glucose testing after delivery
  • Regular diabetes screening
  • Maintaining a healthy lifestyle

There is an increased risk of developing Type 2 Diabetes later in life.

Next Steps

If you’ve been diagnosed or are at risk, early support and guidance can help you manage your health and your baby’s wellbeing.
