The one hour result is way too high and is indicative of diabetes.
You should tell a pediatric endocrinologist these results. I beleive that your daughter has diabetes. Maybe not so severe yet (it can progress over time). She should be following a lower carb diet and being closely monitored.
Let us know how you and she go.
I decided to do my own Glucose Tolerance Test at home. The day I gave it to her, her FBG was 75.
Then I gave her the sugar water.
At 1 hour her BG was about 200
But by 2 hours it was down to 100.
I felt better about that. I still watch her though. I think I will still take her to a pediatric endo.
Am I worng or are the BG for the tolerance test good?
Sounds like early diabetes to me. The high fasting numbers are a concern.
A1C of 5.7 is also high, though 'within range'. Truely normal A1C should be 4.1 - 4.6.
Truely normal sugars (post meal) should be less than 120 at all times - and actually should be approaching back to the fasting level, which should normally be in the 80s.
I would recommend continue to monitor closely and consider a lower carb diet, particularly avoiding sweet and sugary foods, and limiting starchy foods.
Do follow this closely with her pediatrician.
