Oral Glucose tolerance test

My 5 year old daughter had a OGTT a few weeks ago and I was just curious about the results. We will be going to a endocrinologist soon but in the mean time I was trying to find info on my own. I have indicated low results with a L. Her results are as follows: Fasting 82
30 min 80 L
1 hour 77 L
2 hour 75
2 hr 30 min 61 L
3 hour 60
At the 3 hour mark she started feeling sick to her stomach. I have found some information that indicates that this pattern may be a flat curve but I am not sure whether this is conclusive with hypoglycemia which is what I suspect she is having troubles with.

Thanks in advance, Any information would be appreciated.
