There's no cure to diabetes, the treatment is a combination of insulin and lifestyle management. However, managing type 1 diabetes can be very tough, it's more than reducing blood glucose all the time, blood glucose can drop to dangerously low levels when a person is asleep.
Several research centers have been working on developing artificial system to simulate a real pancreas. Lately, a University of Virginia team announced the Control-IQ artificial pancreas system performed well in a trial with 168 participants aged 14 and older. This system is of course a device with a computer program and an insulin pump.
In the research, users of the artificial pancreas system significantly increased the amount of time with their blood glucose levels in the target range of 70 to 180 mg/dL by an average of 2.6 hours per day since beginning the trial. Artificial pancreas users also showed improvements in time spent with high and low blood glucose, hemoglobin A1c.
This study in particular demonstrates tight blood sugar control overnight so a person can wake up with a blood sugar level close to normal most mornings.
