Glucose tolerance test - why am I getting it so late?

browneyedchik · Mar 23rd, 2012, 06:43 AM

The only reason I'd be invited to the hospital for a Glucose tolerance test is if they susptected Gestational Diabetes. I am 14 + 1 weeks? Why not call me in sooner rather than later (27 weeks)? Isn't that leaving it a bit late to find out if you're diabetic?

My test in my last pregnancy was at 27 weeks as well. I was only tested at 17 weeks because I had already had it once.

If gestational diabetes develops, it normally starts after 20 to 24 weeks of pregnancy.

^ wss. Diabetes doesn't usually develop until the 20th or so week of pregnancy. They usually do the test around 28 weeks.

the one hour glucose screening is done at 26-28wks. if you fail that then you do the gtt.

According to my OB, a lot of the issues with GD are related to growth of the placenta. He said it was "essentially anti-insulin" so as the palcenta grows, your body has more trouble combating the sugars with your own insulin production, for people who wind up with GD.

Some doctors might test you early if you are considered high risk for GD. The risk factors include weight, age, family history of diabetes, recent or redcurrant miscarriages, and something else I can never remember. I had my first GTT at 11 weeks due to risk factors, but I passed.

I was tested again at 27 weeks, during the normal time period that all pregnant women should be tested which is 26 to 28 weeks as mentioned previously.

They're doing the 2 hour fasting one at 26-28 weeks for me where you go to the hospital for a blood test having not eaten anything for 12 hours. After the test they give you a bottle of lucozade or gatorade and make you hang around for 2 hours before performing another test.

If you fail, then you're called in for monitoring and frequent blood test to check up on your progress and baby's growth.

We are only given the test if we're considered high risk due to previous pregnancies or if it runs in the family.

I found out from my midwife that the reason they called me in for a test is because I had stated that both my parents had type 2 diabetes. With pervious pregnancies, the GTT was never offered to me because my parents had not developed diabetes type 2 (apparently it's not uncommon for people to develop it after their 60s). Dispite the fact that my parents were perfectly healthy before their 60's I am still classed as having a slightly higher risk of developing GD, if that makes sense.

Really glad you passed. Fingers crossed, I will too. Does it run in your family history?
