glucose tolerance test not normal

[jimmydfi]

I have been lightheaded for more than 25 weeks all day. My chest gets tight daily also. My dr had me do a glucose tolerance test.

fasting= 81
1 hr= 85
2 hr= 64
3 hr= 55

He said it was not normal, so he had me do a 5 hour test with insulin levels being tested too.

fasting= 86
1 hr= 78
2 hr= 71
3 hr= 66
4 hr= 72
5 hr= 76

Insulin was low to normal through out the test. Two of my doctors say this is all normal. Three doctors including an endocronologist say it is not normal. I see the endocronologist on Dec 12. Do you have any ideas what all this could mean? I have been eating healthy for 6 weeks now. I eat every 2 to 3 hours with no symptoms subsiding. I went from 186 to 165 pounds. I am 27 year old male. Thanks for your help.

Hello -

The endocrinolgist should be your central doctor right now so far as this problem is concerned. The results aren't normal. You would seem to be hypoglygemic, which can happen even in the setting of normal insulin levels, as much depends upon how one's insuling receptors work. (This result is sometimes seen as a pre-diabetic metabolic finding, but often it simply means you're hypoglygemic). You've lost weight the way someone with new-onset diabetes would, but I've also known this to happen in hypoglycemics as well, so it's not completely telling.

You should be followed by an endocrinologist, coordinated with an internist. I'm not sure what five doctors you're seeing now, or what other health issues you may have, but the abnormal GTT would seem to coordinate with your symptoms. Hopefully this can be medically managed fairly simply.

I hope this helps. Best of luck to you, and please follow up with us as needed.
