How to Test for Diabetes in Pregnancy

You'll need to take a special blood test called the Oral Glucose Tolerance Test. Here's how it works:
  1. You fast (don't eat) overnight.
  2. Go to the diagnostic lab, and they will check your fasting blood sugar level.
  3. You drink a sweet liquid containing 75 grams of glucose.
  4. Two hours later, they check your blood sugar again.

Facts about Pregnancy Diabetes:

The child born to a mother with GDM is at a high risk for glucose intolerance, diabetes and becoming obese in future.
The baby may be born with breathing disorders and low blood sugar (hypoglycemia).
The most common problem associated with gestational diabetes is macrosomia, in which, baby is born weighing more than 4 kg.
Giving birth to a heavier baby may be a problem at the time of delivery, and hence, cesarean delivery maybe required.
Congenital malformation is one of the reasons why babies die when born to women with gestational diabetes.
If you have a family history of type 2 diabetes, you have a higher chance of developing gestational diabetes.
As it was mentioned, having gestational diabetes increases your risk of developing type 2 diabetes later in life, hence maintaining a healthy lifestyle after pregnancy can help reduce this risk.


Diet Tips for Gestational (Pregnancy) Diabetes:

It is important for a woman with Gestational (Pregnancy) Diabetes to follow a healthy diet  plan and keep her blood sugar (glucose) level under control.
  • Include fat and protein in moderate amounts. Some of the protein rich foods include meat, fish, dry beans, eggs, and nuts.
  • Taking whole fruits is a healthier choice than drinking juice.
  • Your carbohydrate intake must account for less than half of the calories you take. Eat sugar-free sweets.
  • Cut down on hamburgers and cheese that are rich in saturated fats.
  • Spaced-out, balanced meals help regulate blood sugar levels.
  • Pay attention to carbohydrate content in your daily diet and choose whole grains over refined options.
  • Drinking plenty of water helps your body function optimally and can also help reduce cravings for sugary drinks.
Don't hesitate to reach out to your doctor, a registered dietitian, or a diabetes educator for guidance and support throughout your pregnancy.
