Heart Beat: September 2018

Patients with type 1 diabetes require multiple insulin injections a day. This can make it difficult to keep blood glucose levels within the ideal range. Now theres a smartphone app that can help. The Guardian Connect continuous glucose monitoring system works hand-in-hand with the Sugar:IQ app to analyze how patients glucose levels are responding in real time to food intake, insulin and other variables. Data are sent to the cloud for processing, and the information is returned to the app for viewing on an iPhone. The system helps patients identify foods and habits that cause their glucose to spike, as well as times of the day or week when glucose levels fluctuate. This allows them to adjust their insulin use accordingly. In a pilot study, patients using the system spent 33 minutes more per day in the ideal glucose range and had one less hyperglycemic event per month. When the Sugar:IQ app explained the dangers of hypoglycemia, the number of hypoglycemic events dropped in more than half of app users. The system, which has been approved by the U.S. Food and Drug Administration (FDA), is now being retooled for Android users.
