Insulin Pumps

The issue

An insulin pump is a medical device used by people with diabetes. It's an alternative to multiple daily injections of insulin using a syringe or pen.

Insulin pumps are becoming increasingly popular. However, they are complex devices. It's important to know how to use the pump properly to avoid problems or address them if they occur. If you do not know how to use your pump properly to maintain your blood sugar levels, or if there are problems, you are at risk of serious side effects from uncontrolled diabetes.

How insulin pumps work

Insulin pumps are worn externally and deliver a continuous amount of fast-acting insulin 24 hours a day.

There are three main components to insulin pump therapy:

The main steps to using the pump include placing the insulin-filled reservoir inside the pump, and inserting the cannula under your skin using a needle. The cannula is held in place with an adhesive (sticky) patch for 24 to 72 hours, after which time it should be replaced. A tube connects the cannula to the reservoir in the pump and delivers a set amount of insulin into your body.

Two types of insulin doses are delivered to your body by the pump:

The pump can be worn in many places on your body. It can be attached to your waistband, pocket, bra, armband, or underwear. When you sleep, you can lay it next to you on your bed or nightstand. You can disconnect the pump for activities such as swimming or showering. Insulin pumps that are not waterproof should not be exposed to water. 

It's important to make sure that your insulin pump and related components suit your body type and lifestyle. Talk to your doctor for help and advice in choosing an insulin pump, developing an insulin treatment plan and selecting the dose that's right for you.

Side effects

Side effects can happen for a number of reasons, including improper diabetes management, improper use of the insulin pump or its related components, or pump failure. It's important to be aware when you might be having a side effect and know what to do if it happens. Some serious complications of uncontrolled diabetes include:

Talk to your health care provider ahead of time so you know what to do if you have a side effect. Report all side effects to your health care provider. If you or someone you know have side effects like weakness, fainting or loss of consciousness, get medical help immediately!

Complaints involving device problems should also be reported to Health Canada.

Reduce your risk

Insulin pump therapy is not for everyone. You should have a proven history of good diabetes management. As well, you need to be willing to undergo training on an ongoing basis to learn how to use insulin pump therapy to properly manage your diabetes. If you are thinking about using insulin pump therapy, talk to your health care provider about its benefits and risks. Ask about other treatment options to find out which option is best for you and your lifestyle.

Tips for using insulin pump therapy

If used properly, insulin pumps and their related components are reliable and safe. But as with any technology, problems can sometimes occur. It's important to be aware of potential problems and what to do if they arise, to maintain blood sugar levels and avoid side effects.

Tips for proper insulin pump therapy include:

It is very important to monitor your blood sugar regularly and be aware of any signs that there may be a problem, so you can take action before a side effect occurs. Talk to your health care provider about steps to maintain blood sugar levels in case of device problems.

If you have a technical problem with your pump, contact the manufacturer. Manufacturers must provide manuals and training to clearly explain how to use insulin pumps. They must also tell you what to do if you have a side effect or if the device fails.

You should also report technical problems to Health Canada's Health Products and Food Branch Inspectorate.
