Excellent news

Artificial pancreas systems are a few steps closer. That is absolutely amazing news.

A test run of an "artificial pancreas" that monitors blood sugar and delivers both insulin and regulatory hormone called glucagon helped patients achieve near-normal blood sugar levels for more than 24 hours, U.S. researchers said on Wednesday.

The system -- made up of a glucose monitor, two pumps and a laptop -- is designed to better mimic the body's natural mechanism of controlling both high and low blood sugar.

In previous tests of artificial pancreas systems that deliver only insulin, some patients have developed dangerously low blood sugar, known as hypoglycemia.

Adding small doses of glucagon, a hormone released by the pancreas to raise blood sugar levels, helped overcome this, according to the study published in the journal Science Translational Medicine.
