Gestational Diabetes OGTT Results

Determining the Normal Gestational Diabetes OGTT Results

gestational diabetes OGTT resultsIn order to get diagnosed for gestational diabetes, one has to undergo the oral glucose tolerance test or OGTT. The gestational diabetes OGTT results will determine whether you have gestational diabetes or not and what you can do to manage it. Keep in mind that OGTT is a confirmatory screening test for gestational diabetes, meaning higher than normal OGTT results already mean that you are suffering from gestational diabetes. Before you undergo this, you will first be asked to do the one-hour glucose challenge test between 24 and 28 weeks of gestation to see if you have a predisposition to develop gestational diabetes. Those who are seen to be at high risk for gestational diabetes go for the OGTT.

Preparation and Procedure for OGTT

Prior to determining the OGTT results, you have to prepare yourself for the test first. Your doctor will ask you to eat at least 150 grams of carbohydrates for three days before you are asked to fast for the test. This will ensure the validity of the gestational diabetes OGTT results. Fasting starts 8 to 14 hours before the test; all you will be allowed are small sips of water. It is best to schedule the OGTT first thing in the morning so that the hours that you sleep at night will be counted as fasting periods. Regardless of the gestational diabetes OGTT results, you might feel weak and lightheaded after the test because of energy depletion, so you should avoid driving afterwards. Instead, plan to have someone drive you home after the test.

Once you arrive at the laboratory, a blood sample will be extracted to determine your fasting gestational diabetes OGTT results. After that, you will be asked to drink and finish a glucose solution. For three hours after drinking it, blood samples will be extracted to determine your gestational diabetes OGTT results.

Gestational Diabetes OGTT Results

Your gestational diabetes OGTT results will be the key in diagnosing the condition. Basically, you will be treated as a gestational diabetic if two out of four of your gestational diabetes OGTT results are abnormally higher than normal. The normal gestational diabetes OGTT results are a fasting blood sugar of 95 mg/dl or lower, one-hour postprandial blood sugar of 180 mg/dl or lower, two-hour postprandial blood sugar of 155 mg/dl or lower, and three-hour postprandial blood sugar of 140 mg/dl or lower. Some considerations may be made depending on the health care provider, but in general, a value of 200 mg/dl in any of the gestational diabetes OGTT results is already indicative of gestational diabetes.

Once your gestational diabetes OGTT results are deemed abnormally high, you doctor might suggest some lifestyle changes, such as dietary and activity changes. You will be asked to cut back on foods that have a high glycemic index, and to engage in regular exercises that are safe for pregnancy. You might also be given insulin medications if your gestational diabetes OGTT results remain high and uncontrollable. Monitoring of blood sugar levels throughout pregnancy is essential to prevent gestational diabetes from worsening.
