Do I Have Gestational Diabetes?

Once you are suspected to have gestational diabetes, you will be subjected to an oral glucose tolerance test to determine whether or not you really have gestational diabetes. For most women who are going to undergo this test, this can be nerve-racking as they do not know what to expect. Hence, it is very important to educate yourself regarding the glucose tolerance test so that you know the preparation, the procedure, and the normal values for the test results. This will also prevent you from subjecting yourself to undue stress that might adversely affect your baby.

What is the one hour glucose tolerance test?

The oral glucose tolerance test, also known as the one-hour glucose challenge test, is administered between weeks 24 and 28 of your pregnancy. This test will initially determine whether or not you are at risk for developing gestational diabetes. The results of this test are not conclusive, for a high value is still subject to a confirmatory test, the three-hour glucose tolerance test. A high value in this test means that you indeed have gestational diabetes.

How do I prepare for the one hour glucose tolerance test?

For the one-hour glucose tolerance test, there is no preparation required. You can take it right there and then since no fasting is needed. However, if you are going to undergo the three-hour glucose tolerance test, you need to fast for 10 to 14 hours before the test. You should also refrain from drinking or eating anything during the three-hour duration of the test.

What happens in the one hour glucose tolerance test?

one hour glucose tolerance testIn the one-hour oral glucose tolerance test, you will be asked to drink a sugary beverage that contains 50 grams of glucose. After finishing the drink, your doctor will wait for one hour before testing your blood glucose levels. During this one hour, you cannot eat or drink anything. After one hour, your doctor will extract a blood sample from you and compare your values with that of the normal range. If your blood sugar level is less than 130 mg/dl, this means that you do not have gestational diabetes and you will not be subjected to any more tests. However, once the value exceeds 130 mg/dl, you might have gestational diabetes, but the doctor needs to make sure first. Hence, you will be subjected to the three-hour glucose tolerance test. This means that the results of the one-hour glucose tolerance test only determine the possibility of having gestational diabetes, but they do not establish the fact that you really have gestational diabetes.

Once you are subjected to the three-hour glucose tolerance test, your doctor will first draw a blood sample after your 14-hour fasting. Next, you will be asked to drink a sugary liquid containing 100 grams of glucose, then have your blood samples taken one, two, and three hours after finishing the drink. This means that your blood sample will be taken for a total of four times. The normal values for this test should be 95 mg/dl for your fasting blood sugar, 180 mg/dl after one hour, 155 mg/dl for two hours, and 140 mg/dl for three hours. Any two values exceeding this range confirm your condition of gestational diabetes.

It goes without saying that women who have gestational diabetes (GDM) should control their blood sugar levels. Just like other types of diabetes, the main problem in GDM is that the spiking blood glucose levels might cause problems for the pregnant mom. In order to keep the sugar under control, there are certain measures that every mom-to-be should know, especially the ones who are suffering from GDM. One of these measures is knowing how to take glucose levels in the blood, and this can be accomplished in a number of ways.  With gestational diabetes, you may have to do a blood sugar test up to 4 times per day.

Taking Blood Sugar Levels For Gestational Diabetes

There are several ways to determine the blood sugar levels of an individual. One of the most common is fasting blood sugar, more popularly known as FBS. This test is used to diagnose a person with in the diabetes or even pre-diabetes stage.  Eight hours of fasting is needed prior to this test to yield accurate results.

Another way of measuring glucose is through RBS or random blood sugar testing. As the name implies, this test is taken regardless of the last time you ate. This may be taken several times throughout the day, and is very useful for comparing values. Usually, healthy people do not have wide variations when it comes to blood sugar levels throughout the day, so those with noticeable fluctuations might be indicative of a problem. However, this is not a specific test for diagnosing diabetes.

The most common way of diagnosing GDM is through the oral glucose tolerance test or OGTT. In here, the woman is asked to drink a glass of a glucose-containing liquid. Afterwards, her blood sample will be taken to determine whether she has GDM or not. Once the woman is diagnosed with GDM, she might be asked to monitor her glucose levels throughout pregnancy through a glucometer and glucose strip, which should be taken at least two hours after meals.

Recommended Glucose Levels

In every glucose test, there is a corresponding glucose level that is deemed to be normal. Anything over that can strengthen the proof or even diagnose a pregnant woman with GDM. For example, in FBS, a glucose level of more than or equal to 95 mg/dl is already considered to be diabetic. This level can already be detrimental to the health of both the mother and the baby. If the glucose levels are tested one hour post-prandial or after eating, a value of more than or equal to 130 mg/dl is indicative of a glucose absorption problem. Two hours after eating, a pregnant woman should have less than 120 mg/dl in order to be considered healthy.

However, it is important to remember that a very low glucose level of less than 60 mg/dl is indicative of hypoglycemia, and can cause hunger, dizziness, confusion, and weakness.

Keeping a Food Log

If you are diagnosed with GDM, it is essential to keep a food log so that you know which foods increase your blood sugar levels, and which ones only do so minimally. Aside from that, you should also take note of your portion size, especially for foods high in sugar and carbohydrates.

Even getting a great book on meal planning will help.  Be sure to consult your nutritionist regarding a diet plan to keep your glucose levels in check.

That being said, it is essential to include a variety of foods in your meal plan: vegetables; fruits; milk and milk products; meat, poultry, and fish; and bread, rice, and pasta.

The last food group is full of carbohydrates, and these are the ones that are broken down into glucose and used by the body. Nevertheless, this does not mean that you should avoid eating carbohydrates altogether, since that is not an option. Carbohydrates are still needed by the body, as they are the main sources of energy for the body. What you can do is to moderate your intake of carbohydrates; that is, only consume not more than three servings for each of the main meals. It is also important to choose foods that are broken down into glucose slowly, since this helps avoid spikes in a woman’s blood glucose level. Examples of these foods are whole grain breads and plain yogurts. You can also opt to combine carbohydrates with protein-rich foods so as to balance your diet.

However, it is not wise to completely obliterate sugar-rich foods in one’s diet, since sugar is also another source of energy for the body. One way to incorporate sweets into your diet is to eat a slightly lower amount of carbohydrates in a specific meal, and then allow yourself a little bit of sugar in return. You can also add sweets into your meal if the food you are eating has a low glycemic index, meaning glucose is broken down slowly. Remember, you cannot indulge in sweets, but you can have a little bit of it in your diet.
