The GC test has become routine. Higher-risk mothers, older mothers, and women with a family history of diabetes mellitus are screened earlier, and or more frequently. Most have never had a problem or a history of diabetes. Most studies indicate that getting gestational diabetes is directly related to the changes in hormones during pregnancy that causes this condition.
Gestational diabetes usually shows up in the last trimester, at the end of the pregnancy, although some women develop it at the end of the second trimester. Your baby depends on you for nourishment, in the way of glucose sugar.
Your sugar levels in the blood are regulated by insulin. Pregnancy triggers an anti-insulin mechanism to make sure enough sugar circulates to get to your baby.
Most of the time it works perfectly, except when it does not. This usually happens in the second trimester, to the extent that roughly half the pregnant women have some sugar in their urine at some point in their pregnancies. Most women produce an increase in their insulin levels to compensate. Women who have diabetic tendencies may not be able to produce enough insulin to compensate for the increase in blood sugar or are not able to use their insulin efficiently.
Nutrition plays a big part in your health and even more so during your pregnancy. Going into pregnancy overweight can increase some risk factors, but although pregnancy is not the time to lose weight, you need to watch your diet.
Every bite you put in your mouth can affect both of you, you and your baby, so make it count. Become a label reader. Know the difference between carbohydrates.

Then blood samples will be collected at timed intervals of 1,2, and 3 hours after you drink the glucose. Oral Glucose Tolerance Tests The purpose of the oral glucose tolerance test is to measure the body's ability to use a type of sugar, called glucose.
How To Prepare - 1 hour test Eat a meal low in carbohydrates before this test. Your doctor will give you a sugary drink containing 50 grams of glucose for you to drink. After drinking the glucose, you will need to have your blood drawn 1 hour later to test for your blood glucose levels. If your levels do not come back normal, you will be asked to come back for additional testing. The second step of the test is a 3 hour oral glucose tolerance test.
With this test, you will need to be fasting before going to your doctors office. You will then have your blood drawn again at 1 hour, 2 hours and 3 hours after drinking the glucose. If any of the 4 blood glucose level draws are higher than normal, you may be diagnosed with gestational diabetes. Depending on which strategy your doctor performs in their practice will determine if you will be allowed to eat before your test or not.
It is common to worry about it — it is a test after all. Avoid anything high in sugar and simple carbohydrates. This is because they can send your blood sugar sky rocketing, which when you drink the sugary glucose drink your doctor gave you, it will only go higher.
This may lead to a false positive. Avoid foods commonly high in simple carbohydrates, such as:. Note that the above list is not all inclusive of foods to avoid, nor is it defining of each item. As always, read the nutrition facts labels and ingredients list to help guide you in making a decision.
