What to Eat Before Glucose Test Pregnancy For Accurate Results

3 min read

There are a lot of doctor’s visits and tests you’ll need to have done to ensure that both you and your little one are healthy. One of these tests is the glucose test pregnancy, which is also known as the gestational oral glucose tolerance test (OGTT).


This test would screen you to see if you are at risk of gestational diabetes. It’s taken between your 6th or 8th month of pregnancy if you haven’t been diagnosed with diabetes.


There is no preparation before the test, though your doctor will give you something to drink an hour before the test for your sugar levels to peak.


If you're worried about the results, there are dietary changes to help maintain your blood sugar levels before the test.


What Is Gestational Diabetes?

Gestational diabetes happens when a pregnant woman’s body can’t regulate their glucose levels, resulting in high sugar levels. This happens due to hormones and weight gain from pregnancy.


What to Eat Before Glucose Test Pregnancy

You will need to fast about eight hours before going to your doctor’s office. They will draw blood for testing your fasting glucose level, then you will have the sugary drink (75 grams of glucose). They will then draw your blood one hour after drinking.


When figuring out what to eat during the days before the test, it's best to stick with nutrient-dense foods with complex carbohydrates and fiber. Here are some examples:

  • Whole wheat bread and pasta
  • Brown rice or quinoa
  • Beans and lentils
  • Nuts and/or nut butter
  • Oats
  • Seeds
  • Certain fruits less in sugar
  • Non-starchy vegetables)
  • Meat, poultry, eggs, and fish
  • Soy
  • Oils
  • Cheese 

Besides what to eat, there are also certain foods you have to avoid. You should NOT have simple carbohydrates or food high in sugar. This can have your blood sugar levels spike, leading to a false positive.


Do not have:

  • Sugary breakfast cereals
  • White bread or bagels
  • Chips and crackers
  • Fruit smoothies and yogurts
  • Donuts and/or pastries
  • Muffins, cookies, cakes
  • Ice cream
  • Candies
  • Soda, sweet tea, or sports drinks
  • Juice and flavored coffee 

I recommend that you still follow this list even after the glucose test, as this can manage your blood sugar levels to avoid such conditions.


Besides what to eat, you can also follow these extra tips when taking your glucose test:

  • Schedule the test appointment in the morning to help make fasting easier
  • If you’re thirsty, you’re allowed to take small sips of water
  • Create a meal plan after the test or pack snacks in your bag to avoid feeling ravenous and lightheaded  

What If I’m Still Positive?

Eating these healthy foods won’t guarantee normal levels of blood sugar levels. When your body is already in gestational diabetes, then a change of diet won’t alter the test results.


But don't worry, as this is also common since our hormones can change a lot during pregnancy and there are ways to live with the condition. Don't beat yourself up because of it!


If the diagnosis is confirmed, then you can work with your doctor to help keep a healthier diet and an active lifestyle to manage it.


Furthermore, gestational diabetes usually goes away after childbirth!


Wrapping It Up

Diet is crucial when pregnant, which can help regulate your hormones and maintain optimum health. Lessening food high in carbs and sugar can prevent or manage gestational diabetes, among other benefits.


So start referring to this list on what to eat and avoid to make the proper dietary changes now.
