Question: Glucose Tolerance Test - pre-diabetic or diabetic?

 guest51 - Thu Dec 18, 2008 1:24 am

I'm a 53 year old woman who just had a 3 hour glucose tolerance test, here are my results:
Fasting - 106
1 hour - 210
2 hour - 230
3 hour - 167
I'm not sure if these results mean I'm a pre-diabetic or diabetic. Thank you for your help in advance.

User avatar Hi,
I'm afraid that does look like it could be a mild case of diabetes. Your fasting glucose is normal but your 1 and 2 hour tests are >200 and your 3 hour test is >140. Please note that this may need confirmation and needs to be correlated with your symptoms. Also note that sometimes they vary from lab to lab and that the meaning of your test depends on many other factors. What did your doctor say?

Please keep us updated.

Thank you so much for your quick reply, I haven't seen my doctor yet, my appointment isn't until next month but got my labs results from her nurse. I will post again after talking with her, thanks again.

Well, it turns out I do have diabetes, my insulin levels were over 300. Since starting finger sticks, my glucose numbers have been pretty good, fasting average is about 108 non fasting average is about 125. These glucose numbers look pretty normal from everything I've read, why do I have these normal glucose numbers and such high insulin numbers??

User avatar Hello,

Thank you for the update. I am not a diabetologist/endocrinologist but this does look like insulin resistance. This can be the pattern in Type II (maturity onset diabetes).

However, I will refer this post to our Endocrinology Team and hopefully someone will give us a better assessment of your results.

Best regards,

User avatar Hi guest51,
I am from the endocrinology team on this site. I am really sorry that there was a delay in this reply.

Your tests indicate that you have a form of diabetes that is common in adults, who have developed a resistance to the action of 'insulin', the glucose utilizing hormone.
Such results would mean that the pancreas (the gland that pours insulin into blood) may get 'exhausted' in a couple of years, and you might need medication.
It will be kind of you to provide us with your weight and height, so that we can calculate the BMI (Body Mass Index). This will help us in further discussing the case with my colleagues.
I'll also advise you to exercise regularly and keep a check on your cholesterol levels.
Dr. N. Haider
