The Effect of Glycemic Index on Post-prandial Glycemia (Breakfast vs. Lunch) in Patients With Type 1 Diabetes: Quantification With Continuous Glucose Monitoring
In Brief
A clinical study evaluating Dexcom Seven® Plus Continuous Glucose Monitoring sensor for Type 1 Diabetes Mellitus. Completed, enrolled 7 participants across 1 site.
Detailed Summary
Background: Post-prandial hyperglycemia is common in people with type 1 diabetes. Objective: The aim was to determine the impact of low vs high glycemic index (GI) on post-prandial glycemia for breakfast vs lunch and to quantify these effects with continuous glucose monitoring. Design: Seven adult subjects with type 1 diabetes participated in two experiments, each consisting of two meals each. In one experiment, both meals had a low GI; in the other, high GI. Meals were given 195 minutes apart and were matched for carbohydrate, protein, and fat content. Each subject received his usual pre-prandial insulin dosage, followed by a continuous subcutaneous basal insulin infusion for the remainder of the experiment. Arterialized venous glucose was analyzed every 15 minutes and sensor glucose was recorded every 5 minutes.
