Posted on Fri, 1 Jul 2016
Question: Hello,
I am 26 weeks pregnant. This weekend on Saturday I had my gulcose tolerance test (3 hours) on which I failed badly. My fasting numbers were: 172, 1 hour: 325 and 2 hour: 318. I know they are bad but my doctor never told me to follow a strict diet of 3 -5 days prior to the test. In my pregnancy I have been craving for a lot of sweet things so kept having them. Iced tea, cold drinks, juice, Icecream; anything sweet you can think of. This is the reason I think that caused such a high levels of sugar in my blood. To confirm that i have Gestation diabetes I want to retake my test on coming thursday and I have been following the required diet before the test. What do u recommend me? Should I re take it. Can the numbers be lower next time? Should I take high carb diet and avoid all the sugary stuff for test? Please suggest, I am extremely worried. Thankyou!

Brief Answer:
Repeat testing is advisable.

Detailed Answer:
Hello dear,

Thanks for trusting me and hcm about your health care.

I have gone through your history and understand your concerns.

As your previous blood sugar were normal and now they are high in my opinion repeat test is advised to rule out gestational diabetes.

With diet control some control of GGT may occur and reading are on lower side.

Take low carbohydrate and low sugar diet.

Get your hbA1C levels done to see three months blood sugar levels.

Hope found useful, feel free to ask more information.

Good luck.
