Impact of fasting and postprandial glycemia on overall glycemic control in type 2 diabetes Importance of postprandial glycemia to achieve target HbA1c levels.

Objective: HbA1c values reflect overall glycemic exposure over the past 2-3 months and are determined by both fasting (FPG) and postprandial plasma glucose (PPG) levels. Cross-sectional studies suggest that attainment of HbA1c goals requires specific targeting of postprandial hyperglycemia.

Research Design And Methods: We undertook a prospective intervention trial to assess the relative contribution of controlling FPG and PPG for achieving recommended HbA1c goals.
