Induced hyperglycemia – Gestational diabetes test

WHAT IS GESTATIONAL DIABETES?

It is defined by an increase in blood sugar, most of the time during the second trimester of the pregnancy.

In most cases, gestational diabetes disappears after childbirth. However, in some cases, the mother could develop type 2 diabetes in the following years.

The cause of gestational diabetes is the result of hormonal changes experienced during pregnancy: hormones in the placenta interfere with the action of the pancreas. It cannot secrete enough insulin, which leads to hyperglycemia.

Insulin has the role of allowing glucose to enter and thus nourish our cells. Without insulin, a hormone generally secreted naturally by the pancreas, glucose accumulates in the blood stream and thus causes hyperglycemia.

WHAT ARE THE MAIN RISK FACTORS?

  • Being more than 35 years old
  • Suffering from obesity (BMI over 30)
  • Having had diabetes during a previous pregnancy
  • Being pregnant with twins
  • Having delivered a baby over 4 kg (9 lb) in the past
  • Have a close family member with diabetes
  • Take cortisone medication regularly
  • Suffering from polycystic ovary syndrome (PCOS)
  • Suffering from acanthosis nigricans, a brown discoloration of the skin
  • Having had abnormally high sugar levels in the past
  • Women of Aboriginal, Latin American, Asian, Arab or African origin are also at higher risk of developing diabetes in pregnancy

 

WHAT ARE THE RISKS FOR THE MOTHER?

  • Increase the risk that the mother will give birth by caesarean or have a more difficult vaginal birth, because of the baby’s weight
  • Cause pre-eclampsia (pregnancy hypertension)
  • Cause an excess of amniotic fluid which can cause a premature delivery
  • Increase the risk that the mother will develop type 2 diabetes in the long term

 

WHAT ARE THE RISKS FOR THE CHILD?

  • Have a higher weight than the average (more than 4kg or 9lb)
  • Suffering from an arm injury when passing the shoulders during childbirth, due to its higher weight
  • Hypoglycemia (drop in sugar level)
  • Have jaundice
  • Lack of calcium in the blood
  • Having difficulty breathing

 

It is important to know that diabetes in pregnancy does not increase the risk of birth defects or the risk that your child will be diabetic at birth. It does, however, increase the risk of being obese or having glucose intolerance in early adulthood

HOW TO PREVENT DIABETES DURING PREGNANCY?

Doctors advise:

  • Having a healthy weight that reduces the risk of developing gestational diabetes
  • To have a varied and balanced diet
  • Physical activity (walking, swimming, yoga…)

 

WHAT TO DO IF YOU HAVE GESTATIONAL DIABETES?

Your doctor will refer you to an endocrinologist and / or nutritionist who will assess the best treatment for you. Some mothers will be able to fight pregnancy diabetes with a specific diet and others will also need insulin treatment.

 

 

THE GESTATIONAL DIABETES SCREENING TEST AT THE CLINIQUE OVO

All pregnant women will be prescribed an induced hyperglycemia test by their doctor between the 24th and 28th weeks of pregnancy.

If you are at risk, your doctor will likely order a test sooner, around the 12th week of pregnancy.


This is done on an empty stomach, two or three blood tests depending on what the doctor has prescribed.

  • The first blood test will be taken on an empty stomach when you arrive at the clinic. You will then need to drink a very sweet juice.
  • One hour later, another blood test will be taken.
  • Then, when prescribed, you may have to take a third and final blood test two hours after the first one.

COSTS

The price differs depending on the test prescribed by your doctor:

  • 50g: $ 65.00
  • 75g: $ 90.00
