Key Facts: Insulin Pumps at a Glance

What Is an Insulin Pump?

An insulin pump is a small, computerized device that delivers rapid-acting insulin continuously throughout the day and night. Unlike traditional insulin injections, a pump mimics the function of a healthy pancreas by providing a basal rate (continuous background insulin) and bolus doses (mealtime or correction doses). Modern pumps are becoming increasingly sophisticated, integrating with continuous glucose monitors (CGMs) to create automated insulin delivery (AID) systems — also known as closed loop or artificial pancreas systems.

Closed Loop Systems Explained

A closed loop system — often called an artificial pancreas — combines an insulin pump, a CGM sensor, and an algorithm that communicates automatically between the two. The CGM sends glucose readings to the pump every few minutes, and the algorithm adjusts insulin delivery without requiring the user to manually intervene.

There are two main types of closed loop systems:

• Hybrid Closed Loop: The system automates basal insulin but still requires the user to manually bolus for meals. Examples: Omnipod 5, Tandem t:slim X2 with Control-IQ+.
• Full Closed Loop (Advanced Hybrid): The system can also deliver automatic correction boluses in addition to basal adjustments. Example: Medtronic 780G.

Research consistently shows that closed loop systems improve time in range (TIR), reduce hypoglycemia, and lower HbA1c levels compared to traditional pump therapy or MDI. For users considering which CGM to pair with their pump, our Dexcom G7 vs FreeStyle Libre 3: Full Comparison offers detailed insights.

DIY Closed Loop Systems

Beyond commercial options, a growing community of diabetes advocates uses DIY closed loop systems such as Loop, OpenAPS, and AndroidAPS. These open-source algorithms connect compatible pumps (like older Medtronic models or OmniPod DASH) with CGM data through a smartphone or small device. While DIY systems are not FDA-cleared and require significant technical knowledge, they have helped many users achieve excellent glucose control and have even influenced the development of commercial AID systems.

Choosing the Right Insulin Pump: Key Considerations
