To minimize the risk of microvascular and macrovascular complications, it is important to focus on detecting postprandial hyperglycemia, but it is only recommended to measure blood glucose (BG) 60 – 120 minutes after a meal if the preprandial BG is normal and HbA1c is increased. Thus the aim of this study was to investigate whether an alternative measurement interval of 120 – 180 minutes after a meal would outperform the recommended interval. Continuous glucose monitoring data, spot capillary blood glucose and carbohydrate intake times were collected from 23 type 1 Diabetes Mellitus patients. BG levels within 180 minutes after a meal were investigated, and the time the patients spent in postprandial hyperglycemia (BG >10 mmol/L) was converted to percentage for each interval and compared to all meals together, and to breakfast, lunch and dinner, respectively. No significant differences were found between the recommended interval and the alternative interval.
