Benefits

Hover over the boxes below to learn more:

A reduction in hypos and return of hypo awareness

The ability to manage exercise and activity more accurately

Improved control and flexibility

More accurate insulin delivery through built in calculators* and ability to micro-dose insulin

No daily injections

*This includes pre-programmed insulin: carb ratios (ICRs), insulin sensitivity factors (ISF), to help calculate mealtime and correction doses, and “active insulin” feedback to assist in dose calculation.

Challenges include:

• An infusion set change is required every 2–3 days

• Risk of site infection 

• The pump may malfunction and infusion set can block

• Risk of Diabetic Ketoacidosis (DKA) which can occur sooner than with insulin injections

• Must monitor blood glucose 4–6 times daily

• Must have a good knowledge of carbohydrate counting

• The Pump must be worn 24hrs a day, everyday

• The Pump can be disconnected but only for a maximum of 1 hour at a time

• Complications such as lipohypertrophy (lumpy injection sites) can still occur using the pump.
