In September, the Food and Drug Administration approved the first artificial pancreas - a major step forward for those affected by Type 1 diabetes.

The development is exciting news for those who have stressed for years about constantly drawing blood to calculate glucose levels.

The artificial pancreas is about the size of a smartphone, and users will wear it like they would an insulin pump.

While the device does a lot, users will still need to do a finger prick twice a day, and a daily estimation of what they're eating.

"Patients will still need to enter into the device what they're eating to some degree. The difference is, if they make an error the system will correct it," says Carol J. Levy, medical director at Mount Sinai Brooklyn.
