The lows are pretty classic reactive hypoglycemia. A person who is insulin resistant but not yet insulin deficient will have a delayed response to the glucose load, causing the body to push out more insulin, eventually resulting in a hard crash, especially when there's no protein or fat to buffer the simple carbs, like in a gtt. The solution is a low glycemic diet with protein and fat accompanying carbs. It's a fairly common part of pre-diabetes.
