| Re: results of 2 hour GTT
The OGTT is used to diagnose type 2 diabetes or the milder form of it, pre-diabetes. Normal fasting blood glucose is 70-90, and 100-125 indicates pre-diabetes. With your FBG of 98, you are getting close but you aren't quite there yet. And the OGTT result suggests reactive hypoglycemia. At the 2 hour mark, <140 is considered normal, 140-200 indicates pre-diabetes, and >200 is type 2 diabetes. Your blood glucose dropped to 54 after 2 hours, suggesting that your beta cells over-reacted to a blood glucose spike by producing too much insulin (which made your blood glucose drop).
T2 diabetes often starts this way, but many people who have reactive hypoglycemia never become T2 diabetics. You also could be in the very early stages of type 1 diabetes onset. As you have a family history of type 1 diabetes, you may want to rule this out by having the antibody tests done.
