Definition: Postprandial literally means "after a meal." For people with diabetes, it refers to blood glucose measurements taken 1-2 hours after a meal. This is known as the postprandial blood glucose level and is an important measurement to take because it shows how a meal affects blood glucose. This helps people with diabetes figure out which meals keep their blood glucose levels in good control, and which meals may make blood glucose spike too high.
Examples: Check the postprandial rise in blood glucose levels 1 to 2 hours after eating a meal.
