Insulin pump therapy

Diabetic patients may be prescribed daily doses of insulin in order to maintain their blood glucose levels. Often patients inject themselves with insulin several times per day.

What is an insulin pump?

An insulin pump is a computerised device which serves as an alternative to multiple daily injections. It is made up of two components:

• A pump with a reservoir that holds insulin. This device is the size of a pack of playing cards and can fit in a pocket or clip on a belt.
• A long, thin tube with a very fine needle (called a cannula) at the end (called an infusion set). The needle is inserted into the skin allowing your body to absorb the insulin gradually.
  

Some insulin pumps use only a patch that is attached directly to your skin. This type does not require any tubing or cannula.

The pump delivers a prescribed amount of insulin throughout the day. The user can increase the doses as needed.

Insulin pump therapy may not be an option for all patients. Be sure and discuss the pros and cons with your consultant.
