How does the insulin pump monitor your blood sugar?

Pump gives insulin: The Insulin pump is an electronic device that delivers Insulin at precise rates and times through a tube under the skin. People using Insulin pumps still test their sugar levels by using a glucose monitor, to figure out whether their Insulin pump rates are correct. Medtronic does make a continuous glucose sensor inserted under the skin, that can be used to transmit sugar data to its Insulin pump.

Continuous Glucose M: An Insulin pump such as the minimed pump has an extra feature to monitor blood glucose or you can get a separate Continuous Glucose Monitors called Dexcom. These are useful for diabetics who have unexplained swings in their blood sugars especially when diabetics have hypoglycemia unawareness (unable to feel low blood sugars).
