Postprandial glucose
Glucose usually checked about two hours after a meal.
Postprandial means after eating. Checking glucose around two hours after a meal shows how your body handled that food: the rise, the peak, and the return toward baseline.
The peak itself often lands nearer one hour after starting the meal; the two-hour value is the standard time point clinicians use. Both are useful: a one-hour reading shows how high the meal took you, and the two-hour reading shows how quickly you came back down.
Pairing a post-meal reading with a note about what you ate is one of the most useful habits for spotting which meals suit you.
