What does glucose excursion mean in this context within?

Postprandial by the way means after a meal.

Background: Postprandial plasma glucose (PPG) excursion is a significant determinant of overall metabolic control as well as an increased risk for diabetic complications. Older persons with type 2 diabetes mellitus (DM2) are more likely to have moderate cognitive deficits and neurophysiologic and structural changes in brain tissue. Considering that poor metabolic control is considered a deranging factor for tissue/organ damage in diabetics, the authors hypothesized that PPG excursion is associated with a decline in cognitive functioning and that a tighter control of PPG may prevent cognitive decline.
1st answerer that didn't help at all…I just want a CLEAR definition of what it means, I've already looked on google and can't find the meaning.

    postprandial glucose excursions (PPGEs) is the change in glucose concentration after a meal and the incremental glucose area

    the incremental glucose area is the area under the glucose curve that is above the premeal (or pre– oral glucose tolerance test [OGTT]) value

    So I believe it is the rate of removal of glucose from the blood, and it is similiar to the idea of the glycemic index.
