At this next regular check up appointment, I will be tested for Gestational Diabetes. I've been told some horror stories on the solution to drink! Here's more on what it is:

Glucose Tolerance Test

Gestational diabetes sure ain't sweet — but it is manageable. Here are the details on glucose screening and diagnostic tests.

What it screens for: A one-hour glucose test screens for (but does not diagnose) gestational diabetes mellitus (GDM). If your sugar levels seem high after a one-hour test, you'll have to come back for the three-hour version, which will give you a firm diagnosis. Gestational diabetes can usually be controlled with a special diet and exercise. (In rare cases, women need insulin to regulate their sugars during pregnancy.)

Who it's for: Most practitioners routinely screen all pregnant women for gestational diabetes. Some screen only women at higher risk for the disorder, including those who are obese or have a family history of diabetes.

How it's done: First, you drink a special glucose (aka sugar) mixture (think flat soda). Then you sit and wait (be sure to bring some reading!). Some practitioners may give you the mixture in advance of that particular appointment, so you arrive primed and ready to be pricked (just don't be late!). Exactly one hour later, your blood is drawn and tested for glucose. A high level of glucose at this point doesn't mean you have gestational diabetes; it just means you need the next test. For that tolerance test, you will be asked to fast overnight. Your blood will be drawn in the morning, and then you drink a different glucose mixture. Your blood will be drawn three more times, at one, two, and three hours later. (Triple the fun!)
