About
Establish a cohort study to describe the characteristics of gastric emptying in patients with type 1 diabetes, and adjust the timing of insulin injection during meals to improve blood glucose fluctuations according to the speed of gastric emptying.
Full description
T1DM that met the inclusion criteria was tested with baseline blood routine, biochemical and complication screening, and FGM monitoring for 14 days (patient blindness) on the basis of the original regimen (insulin pump or basic insulin combined with fast-acting insulin before three meals); A stable diet should be maintained before and during the study.
T1DM that met the inclusion criteria was tested with baseline blood routine, biochemical and complication screening, and FGM monitoring for 14 days (patient blindness) on the basis of the original regimen (insulin pump or basic insulin combined with fast-acting insulin before three meals); A stable diet should be maintained before and during the study.
On the 7th day of FGM monitoring, 13C-GEBT examination was performed on an empty stomach;
Starting from day 8, patients were divided into groups according to the comparison of gastric emptying T50 with pre-experimental healthy people. Group A, patients with rapid gastric emptying, adjusted the time of fast-acting insulin injection to 15 minutes before meals; Group B, patients with slow gastric emptying, adjusted the time of fast-acting insulin injection to 15 minutes after eating.
FGM monitoring was completed on the 14th day and the study was concluded. 2. On the 7th day of FGM monitoring, 13C-GEBT examination was performed on an empty stomach;
