"Keeping glucose levels from jumping too high or dipping too low may help to reduce the risk of cardiovascular disease, which has been connected to erratic glucose levels in those with diabetes," said Robert Gabbay, M.D., Ph.D., associate professor of medicine, Penn State College of Medicine, Penn State Milton S. Hershey Medical Center, and co-director, Penn State Diabetes Center. "Our study shows that after a high carbohydrate, high fat meal like the pizza used in this study, spacing out insulin given by an insulin pump in two doses, one of which is over an eight-hour period, may keep glucose levels in a more favorable range than a single dose of insulin or a double dose taken over a shorter period."
This study titled, "Optimal Insulin Pump Dosing and Postprandial Glycemia Following a Pizza Meal Using the Continuous Glucose Monitoring System," was published in the April issue of Diabetes Technology & Therapeutics.
The study was initiated thanks to Susan M. Jones, M.S., C.R.N.P., C.D.E., a nurse practitioner, and Jill L. Quarry, M.S., R.D., L.D.N., C.D.E., a dietitian, both of whom noted problems with their diabetes patients.
"We noticed that it was very difficult for those with diabetes who were using insulin pumps to maintain good glucose values when they ate pizza," Jones said. "Because pizza is a favorite food for so many people and good quality of life is eating what you want every now and again, we suggested a study to see how best to help those with diabetes enjoy this common favorite food while maintaining good glucose levels."
Twenty-six volunteers with type 1 diabetes were selected from the patient population at Penn State Hershey Medic
