Two-Hormone 'Pancreas' fights dangerous lows in diabetes

This study tested two versions of an automated insulin delivery system, often called an artificial pancreas, in 15 adults with type 1 diabetes. Researchers wanted to see if a system that automatically gives both insulin and a hormone called glucagon works better at preventing low blood sugar than a system that only gives insulin and suggests eating carbs. Each participant tried both systems during two separate 12-hour hospital stays that included a meal and unannounced exercise.
