A CGM system tracks glucose levels every few minutes, 24/7through a tiny sensor inserted under your skin, either on your abdomen or arm using an automatic inserter. The sensor measures your interstitial glucose level, which is the glucose found in the fluid between the cell. CGM therapy can be used with or without an insulin pump.*

Insulin pump is a battery-operated device which contains a reservoir of quick-acting insulin that delivers both basal (background) and quick-acting insulin doses.
